☁ Usage in cloud :

Comfyui is great for local usage, but I sometimes need more power than what I have...
I have a computer with a 4070 super with 12GB and flux fp8 simple wokflow take about ~40 seconds. With a 4090 in the cloud I can run flux fp16 in ~12 seconds. (There are of course also some workflow that I can't even run locally.)

My referal link for Runpod : https://runpod.io?ref=tkowk7g5 (If you use that i will have a commission, at no extra cost for you.)
If you want to use my nodes and comfyui in the cloud (and can install more stuff), I'm managing an optimized ready-to-use template on runpod : https://runpod.io/console/deploy?template=r32dtr35u1&ref=tkowk7g5
Template name : bjornulf-comfyui-allin-workspace, can be operational in ~3 minutes. (Depending on your pod, setup and download of extra models or whatever not included.)
You need to create and select a network volume before using that, size is up to you, i have 50Gb Storage because i use cloud only for Flux or lora training on a 4090. (~0.7$/hour)
⚠️ When pod is ready, you need to open a terminal in browser (After clicking on connect from your pod) and use this to launch ComfyUI manually : cd /workspace/ComfyUI && python main.py --listen 0.0.0.0 --port 3000 or the alias start_comfy (Much better to control it with a terminal, check logs, etc...)
After that you can just click on the Connect to port 3000 button.
As file manager, you can use the included JupyterLab on port 8888.
If you have any issues with it, please let me know.
It will manage everything in Runpod network storage (/workspace/ComfyUI), so you can stop and start the cloud GPU without losing anything, change GPU or whatever.
Zone : I recommend EU-RO-1, but up to you.
Top-up your Runpod account with minimum 10$ to start.
⚠️ Warning, you will pay by the minute, so not recommended for testing or learning comfyui. Do that locally !!!
Run cloud GPU only when you already have your workflow ready to run.
Advice : take a cheap GPU for testing, downloading models or settings things up.
To download checkpoint or anything else, you need to use the terminal.
For downloading from Huggingface (get token here https://huggingface.co/settings/tokens).
Here is example for everything you need for flux dev :

huggingface-cli login --token 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
huggingface-cli download black-forest-labs/FLUX.1-dev flux1-dev.safetensors --local-dir /workspace/ComfyUI/models/unet
huggingface-cli download comfyanonymous/flux_text_encoders clip_l.safetensors --local-dir /workspace/ComfyUI/models/clip
huggingface-cli download comfyanonymous/flux_text_encoders t5xxl_fp16.safetensors --local-dir /workspace/ComfyUI/models/clip
huggingface-cli download black-forest-labs/FLUX.1-dev ae.safetensors --local-dir /workspace/ComfyUI/models/vae

To use Flux you can just drag and drop in your browser comfyui interface the .json from my github repo : workflows/FLUX_dev_troll.json, direct link : https://github.com/justUmen/ComfyUI-BjornulfNodes/blob/main/workflows/FLUX_dev_troll.json.

For downloading from civitai (get token here https://civitai.com/user/account), just copy/paste the link of checkpoint you want to download and use something like that, with your token in URL :

CIVITAI="8b275fada679ba5812b3da2bf35016f6"
wget --content-disposition -P /workspace/ComfyUI/models/checkpoints "https://civitai.com/api/download/models/272376?type=Model&format=SafeTensor&size=pruned&fp=fp16&token=$CIVITAI"

If you want to download for example the entire output folder, you can just compress it :

cd /workspace/ComfyUI/output && tar -czvf /workspace/output.tar.gz .

Then you can download it from the file manager JupyterLab.

If you have any issues with this template from Runpod, please let me know, I'm here to help. 😊

🏗 Dependencies (nothing to do for my runpod ☁)

Check requirements.txt for the latest dependencies.

🪟🐍 Windows : Install dependencies on windows with embedded python (portable version)

First you need to find this python_embedded python.exe, then you can right click or shift + right click inside the folder in your file manager to open a terminal there.

This is where I have it, with the command you need :
H:\ComfyUI_windows_portable\python_embeded> .\python.exe -m pip install ollama pydub opencv-python ffmpeg-python civitai-py fal_client sounddevice langdetect spacy textblob dill

When you have to install something else, you can retake the same code and install the dependency you want :
.\python.exe -m pip install whateveryouwant

You can then run comfyui.

🐧🐍 Linux : Install dependencies (without venv, not recommended)

Move to the custom_node folder and do : pip install -r requirements.txt

OR

• pip install ollama (you can also install ollama if you want : https://ollama.com/download) - You don't need to really install it if you don't want to use my ollama node. (BUT you need to run pip install ollama)
• pip install pydub (for TTS node)
• pip install opencv-python
• etc...

🐧🐍 Linux : Install dependencies with python virtual environment (venv)

If you want to use a python virtual environment only for comfyUI, which I recommended, you can do that for example (also pre-install pip) :

sudo apt-get install python3-venv python3-pip
python3 -m venv /the/path/you/want/venv/bjornulf_comfyui

Once you have your environment in this new folder, you can activate it with and install dependencies inside :

source /the/path/you/want/venv/bjornulf_comfyui/bin/activate
cd custom_nodes/Bjornulf_custom_nodes
pip install -r requirements.txt

Then you can start comfyui with this environment (notice that you need to re-activate it each time you want to launch comfyui) :

cd /where/you/installed/ComfyUI && python main.py

📝 Nodes descriptions

1 - 👁 Show (Text, Int, Float)

Description:
The show node will only display text, or a list of several texts. (read only node)
3 types are managed : Green is for STRING type, Orange is for FLOAT type and blue is for INT type. I put colors so I/you don't try to edit them. 🤣

Update 0.61 : You now also have 4 other nodes to display format specific values : INT, FLOAT, STRING and JSON (STRING)
These are convenient because these are automatically recommended on drag and drop.

2 - ✒ Write Text

Description:
Simple node to write text / send text to another node.

Below is a simple example of how to use the write text node with a show node :

3 - ✒🗔🅰️ Advanced Write Text (+ 🎲 random option)

Description:
Advanced Write Text node allows for special syntax to accept random variants, like {hood|helmet} will randomly choose between hood or helmet.
You also have seed and control_after_generate to manage the randomness.
It is also displaying the text in the comfyui console. (Useful for debugging)
Example of console logs :

Raw text: photo of a {green|blue|red|orange|yellow} {cat|rat|house}
Picked text: photo of a green house

You can also create and reuse variables with this syntax : <name>. Usage example :

❗ 0.76 - New syntax available :
Groups, with no duplicate, example : {left|right|middle|group=LMR}+{left|right|middle|group=LMR}+{left|right|middle|group=LMR}
Random based on percentage : {A(80%)|B(15%)|C(5%)}

❗ 0.77 - New syntax available :
2 {apple|orange|banana|static_group=FRUIT}s, one {apple|orange|banana|static_group=FRUIT} on the left, one {apple|orange|banana|static_group=FRUIT} on the right

4 - 🔗 Combine Texts

Description:
Combine multiple text inputs into a single output. (can have separation with : comma, space, new line or nothing.)

5 - 🎲 Random (Texts)

Description:
Generate and display random text from a predefined list. Great for creating random prompts.
You also have control_after_generate to manage the randomness.

6 - ♻ Loop

Description:

⚠️ Warning : DEPRECATED, this node doesn't work anymore.
Latest comfyui version just refuse to output 2 times the same value.

General-purpose loop node, you can connect that in between anything.

It has an optional input, if no input is given, it will loop over the value of the STRING "if_no_input" (take you can edit).
❗ Careful this node accept everything as input and output, so you can use it with texts, integers, images, mask, segs etc... but be consistent with your inputs/outputs.
Do not use this Loop if you can do otherwise.

This is an example together with my node 28, to force a different seed for each iteration :

7 - ♻ Loop Texts

Description:
Cycle through a list of text inputs.

Here is an example of usage with combine texts and flux :

8 - ♻ Loop Integer

Description:
Iterate through a range of integer values, good for steps in ksampler, etc...

❗ Don't forget that you can convert ksampler widgets to input by right-clicking the ksampler node :

Here is an example of usage with ksampler (Notice that with "steps" this node isn't optimized, but good enough for quick testing.) :

9 - ♻ Loop Float

Description:
Loop through a range of floating-point numbers, good for cfg, denoise, etc...

Here is an example with controlnet, trying to make a red cat based on a blue rabbit :

10 - ♻ Loop All Samplers

Description:
Iterate over all available samplers to apply them one by one. Ideal for testing.

Here is an example of looping over all the samplers with the normal scheduler :

11 - ♻ Loop All Schedulers

Description:
Iterate over all available schedulers to apply them one by one. Ideal for testing. (same idea as sampler above, but for schedulers)

12 - ♻ Loop Combos

Description:
Generate a loop from a list of my own custom combinations (scheduler+sampler), or select one combo manually.
Good for testing.

Example of usage to see the differences between different combinations :

13/14 - 📏 + 🖼 Resize and Save Exact name ⚠️💣

Description:
Resize an image to exact dimensions. If height or width is set to 0, it will keep the aspect ratio.

The other node will save the image to the exact path.
⚠️💣 Warning : The image will be overwritten if it already exists.

15 - 💾 Save Text

Description:
Save the given text input to a file. Useful for logging and storing text data.
If the file already exist, it will add the text at the end of the file.
I recommend you to keep saving them in "Bjornulf/Text" (Which is in the Comfyui folder, next to output), this is where the node 116 Load text from folder is looking for text files.

16 - 💾🖼💬 Save image for Bjornulf LobeChat (❗For my custom lobe-chat❗)

Description:
❓ I made that node for my custom lobe-chat to send+receive images from Comfyui API : lobe-chat
It will save the image in the folder output/BJORNULF_LOBECHAT/. The name will start at api_00001.png, then api_00002.png, etc...
It will also create a link to the last generated image at the location output/BJORNULF_API_LAST_IMAGE.png.
This link will be used by my custom lobe-chat to copy the image inside the lobe-chat project.

17 - 💾🖼 Save image as tmp_api.png Temporary API ⚠️💣

Description:
Save image for short-term use : ./output/tmp_api.png ⚠️💣

18 - 💾🖼📁 Save image to a chosen folder name

Description:
Save image in a specific folder : my_folder/00001.png, my_folder/00002.png, etc...
Also allow multiple nested folders, like for example : animal/dog/small.

19 - 🦙💬 Ollama Talk

Description:
Use Ollama inside Comfyui. (Require the backend Ollama to be installed and currently running.)
Use by default the model llama3.2:3b and the URL http://0.0.0.0:11434. (For custom configuration, use node 63)

Example of basic usage :

Example of usage with context, notice that with context you can follow up a conversation, "there" is clearly understood as "Bucharest" :

You can also use use_context_file (set to True), this will save the context in a file : ComfyUI/Bjornulf/ollama_context.txt.
This way you can keep using the context without having to connect many nodes connected to each other, just run the same workflow several times.

Example in 3 steps of context file conversation

Step 1 : Notice that for now context is empty, so it will be the first message in ComfyUI/Bjornulf/ollama_context.txt :

Step 2 : Notice that now the number of lines in context file has changed (These are the same as the updated_context):

Step 3 : Notice that the number of lines keep incrementing.

When clicking the reset Button, it will also save the context in : ComfyUI/Bjornulf/ollama_context_001.txt, ComfyUI/Bjornulf/ollama_context_002.txt, etc...

⚠️ If you want to have an "interactive" conversation, you can enable the option waiting_for_prompt.
When set to True, it will create a Resume button, use this to unpause the node and process the prompt.

Example in 3 steps of waiting_for_prompt interactive conversation

Step 1: I run the workflow, notice that Show node is empty, the node is pausing the workflow and is waiting for you to edit the prompt. (Notice that at this moment, it is asking for the capital of France.)

Step 2: I edit the prompt to change France into China, but the node won't process the request until you click on Resume.

Step 3: I click on Resume button, this is when the request is done. Notice that it used China and not France.

Other options :

• You also have control_after_generate to force the node to rerun for every workflow run. (Even if there is no modification of the node or its inputs.)
• You can set max_tokens to reduce the size of the answer, a token is about 3 english characters.
• You can force the answer to be on a single line, can be useful.
• You have the option to keep the mode in VRAM. (If you plan having to generate many times with the same prompt) - Each run will be significantly faster, but not free your VRAM for something else.

⚠️ Warning : Using vram_retention_minutes might be a bit heavy on your VRAM. Think about if you really need it or not. Most of the time, when using vram_retention_minutes, you don't want to have also a generation of image or anything else in the same time.

20 - 📹 Video Ping Pong

Description:
Create a ping-pong effect from a list of images (from a video) by reversing the playback direction when reaching the last frame. Good for an "infinity loop" effect.

21 - 🖼➜📹 Images to Video (FFMPEG Save Video)

Description:
Combine a sequence of images into a video file.

❓ I made this node because it supports transparency with webm format. (Needed for rembg)
Temporary images are stored in the folder ComfyUI/temp_images_imgs2video/ as well as the wav audio file.

22 - 🔲 Remove image Transparency (alpha)

Description:
Remove transparency from an image by filling the alpha channel with a solid color. (black, white or greenscreen)
Of course it takes in an image with transparency, like from rembg nodes.
Necessary for some nodes that don't support transparency.

23 - 🔲 Image to grayscale (black & white)

Description:
Convert an image to grayscale (black & white)

Example : I sometimes use it with Ipadapter to disable color influence.
But you can sometimes also want a black and white image...

24 - 🖼+🖼 Stack two images (Background + Overlay)

Description:
Stack two images into a single image : a background and one (or several) transparent overlay. (allow to have a video there, just send all the frames and recombine them after.)

Update 0.11 : Add option to move vertically and horizontally. (from -50% to 150%)
❗ Warning : For now, background is a static image. (I will allow video there later too.)
⚠️ Warning : If you want to directly load the image with transparency, use my node 🖼 Load Image with Transparency ▢ instead of the Load Image node.

25 - 🟩➜▢ Green Screen to Transparency

Description:
Transform greenscreen into transparency.
Need clean greenscreen ofc. (Can adjust threshold but very basic node.)

26 - 🎲 Random line from input

Description:
Take a random line from an input text. (When using multiple "Write Text" nodes is annoying for example, you can use that and just copy/paste a list from outside.)
You can change fixed/randomize for control_after_generate to have a different text each time you run the workflow. (or not)

27 - ♻ Loop (All Lines from input)

Description:
Iterate over all lines from an input text. (Good for testing multiple lines of text.)

28 - 🔢 Text with random Seed

Description:
❗ This node is used to force to generate a random seed, along with text.
But what does that mean ???
When you use a loop (♻), the loop will use the same seed for each iteration. (That is the point, it will keep the same seed to compare results.)
Even with randomize for control_after_generate, it is still using the same seed for every loop, it will change it only when the workflow is done.
Simple example without using random seed node : (Both images have different prompt, but same seed)

So if you want to force using another seed for each iteration, you can use this node in the middle. For example, if you want to generate a different image every time. (aka : You use loop nodes not to compare or test results but to generate multiple images.)
Use it like that for example : (Both images have different prompt AND different seed)

Here is an example of the similarities that you want to avoid with FLUX with different prompt (hood/helmet) but same seed :

Here is an example of the similarities that you want to avoid with SDXL with different prompt (blue/red) but same seed :

FLUX : Here is an example of 4 images without Random Seed node on the left, and on the right 4 images with Random Seed node :

29 - 🖼 Load Image with Transparency ▢

Description:
Load an image with transparency.
The default Load Image node will not load the transparency.

30 - 🖼✂ Cut image with a mask

Description:
Cut an image from a mask.

31 - 🔊 TTS - Text to Speech (100% local, any voice you want, any language)

Description:
Use my TTS server to generate high quality speech from text, with any voice you want, any language.
Listen to the audio example

❗ Node never tested on windows, only on linux for now. ❗

Use my TTS server to generate speech from text, based on XTTS v2.
❗ Of course to use this comfyui node (frontend) you need to use my TTS server (backend) : https://github.com/justUmen/Bjornulf_XTTS
I made this backend for https://github.com/justUmen/Bjornulf_lobe-chat, but you can use it with comfyui too with this node.
After having Bjornulf_XTTS installed, you NEED to create a link in my Comfyui custom node folder called speakers : ComfyUI/custom_nodes/Bjornulf_custom_nodes/speakers
That link must be a link to the folder where you installed/stored the voice samples you use for my TTS, like default.wav.
If my TTS server is running on port 8020 (You can test in browser with the link http://localhost:8020/tts_stream?language=en&speaker_wav=default&text=Hello) and voice samples are good, you can use this node to generate speech from text.

Details
This node should always be connected to a core node : Preview audio.

My node will generate and save the audio files in the ComfyUI/Bjornulf_TTS/ folder, followed by the language selected, the name of the voice sample, and the text.
Example of audio file from the screenshot above : ComfyUI/Bjornulf_TTS/Chinese/default.wav/你吃了吗.wav
You can notice that you don't NEED to select a chinese voice to speak chinese. Yes it will work, you can record yourself and make yourself speak whatever language you want.
Also, when you select a voice with this format fr/fake_Bjornulf.wav, it will create an extra folder fr of course. : ComfyUI/Bjornulf_TTS/English/fr/fake_Bjornulf.wav/hello_im_me.wav. Easy to see that you are using a french voice sample for an english recording.

control_after_generate as usual, it is used to force the node to rerun for every workflow run. (Even if there is no modification of the node or its inputs.)
overwrite is used to overwrite the audio file if it already exists. (For example if you don't like the generation, just set overwrite to True and run the workflow again, until you have a good result. After you can set it to back to False. (Paraphrasing : without overwrite set to True, It won't generate the audio file again if it already exists in the Bjornulf_TTS folder.)
autoplay is used to play the audio file inside the node when it is executed. (Manual replay or save is done in the preview audio node.)

So... note that if you know you have an audio file ready to play, you can still use my node but you do NOT need my TTS server to be running. My node will just play the audio file if it can find it, won't try to connect th backend TTS server.
Let's say you already use this node to create an audio file saying workflow is done with the Attenborough voice :

As long as you keep exactly the same settings, it will not use my server to play the audio file! You can safely turn the TTS server off, so it won't use your precious VRAM Duh. (TTS server should be using ~3GB of VRAM.)

Also connect_to_workflow is optional, it means that you can make a workflow with ONLY my TTS node to pre-generate the audio files with the sentences you want to use later, example :

If you want to run my TTS nodes along side image generation, i recommend you to use my PAUSE node so you can manually stop the TTS server after my TTS node. When the VRAM is freed, you can the click on the RESUME button to continue the workflow.
If you can afford to run both at the same time, good for you, but Locally I can't run my TTS server and FLUX at the same time, so I use this trick. :

32 - 🧑📝 Character Description Generator

Description:
Generate a character description based on a json file in the folder characters : ComfyUI/custom_nodes/Bjornulf_custom_nodes/characters
Make your own json file with your own characters, and use this node to generate a description.

❗ For now it's very basic node, a lot of things are going to be added and changed !!!
Some details are unusable for some checkpoints, very much a work in progress, the json structure isn't set in stone either.
Some characters are included.

33 - ♻ Loop (All Lines from input 🔗 combine by lines)

Description:
Sometimes you want to loop over several inputs but you also want to separate different lines of your output.
So with this node, you can have the number of inputs and outputs you want. See example for usage.

34 - 🧹 Free VRAM hack

Description:
So this is my attempt at freeing up VRAM after usage, I will try to improve that.

For me, on launch ComfyUI is using 180MB of VRAM, after my clean up VRAM node it can go back down to 376MB.
I don't think there is a clean way to do that, so I'm using a hacky way.
So, not perfect but better than being stuck at 6GB of VRAM used if I know I won't be using it again...
Just connect this node with your workflow, it takes anything as input and return it as output. You can therefore put it anywhere you want.
❗ Comfyui is using cache to run faster (like not reloading checkpoints), so only use this free VRAM node when you need it.
❗ For this node to work properly, you need to enable the dev/api mode in ComfyUI. (You can do that in the settings)
It is also running an "empty/dummy" workflow to free up the VRAM, so it might take a few seconds to take effect after the end of the workflow.

35 - ⏸️ Paused. Resume or Stop ?

Description:
Automatically pause the workflow, and rings a bell when it does. (play the audio bell.m4a file provided)

You can then manually resume or stop the workflow by clicking on the node's buttons.
I do that let's say for example if I have a very long upscaling process, I can check if the input is good before continuing. Sometimes I might stop the workflow and restart it with another seed.
You can connect any type of node to the pause node, above is an example with text, but you can send an IMAGE or whatever else, in the node input = output. (Of course you need to send the output to something that has the correct format...)

36 - ⏸️🔍 Paused. Select input, Pick one

Description:
Automatically pause the workflow, and rings a bell when it does. (play the audio bell.m4a file provided)

You can then manually select the input you want to use, and resume the workflow with it.
You can connect this node to anything you want, above is an example with IMAGE. But you can pick whatever you want, in the node input = output.

37 - 🎲🖼 Random Image

Description:
Just take a random image from a list of images.

38 - ♻🖼 Loop (Images)

Description:
Loop over a list of images.

Usage example : You have a list of images, and you want to apply the same process to all of them.
Above is an example of the loop images node sending them to an Ipadapter workflow. (Same seed of course.)

39 - ♻ Loop (✒🗔🅰️ Advanced Write Text)

Description:
If you need a quick loop but you don't want something too complex with a loop node, you can use this combined write text + loop.

It will take the same special syntax as the Advanced write text node {blue|red}, but it will loop over ALL the possibilities instead of taking one at random.
0.40 : You can also use variables <name> in the loop.

40 - 🎲 Random (Model+Clip+Vae) - aka Checkpoint / Model

Description:
Just simply take a trio at random from a load checkpoint node.

Notice that it is using the core Load checkpoint node. It means that all checkpoint will be preloaded in memory.

Details :

• It will take more VRAM, but it will be faster to switch between checkpoints.
• It can't give you the currently loaded checkpoint name's.

Check node number 41 before deciding which one to use.

41 - 🎲 Random Load checkpoint (Model Selector)

Description:
This is another way to select a load checkpoint node randomly.

It will not preload all the checkpoints in memory, so it will be slower to switch between checkpoints.
But you can use more outputs to decide where to store your results. (model_folder is returning the last folder name of the checkpoint.)
I always store my checkpoints in a folder with the type of the model like SD1.5, SDXL, etc... So it's a good way for me to recover that information quickly.

Details :

• Note that compared to node 40, you can't have separate configuration depending of the selected checkpoint. (For example CLIP Set Last Layer node set at -2 for a specific model, or a separate vae or clip.) Aka : All models are going to share the exact same workflow.

Check node number 40 before deciding which one to use.
Node 53 is the loop version of this node.

NOTE : If you want to load a single checkpoint but want to extract its folder name (To use the checkpoint name as a folder name for example, or with if/else node), you can use my node 41 with only one checkpoint. (It will take one at random, so... always the same one.)

42 - ♻ Loop (Model+Clip+Vae) - aka Checkpoint / Model

Description:
Loop over all the trios from several checkpoint node.

43 - 📥🖼📂 Load Images from output folder

Description:
Quickly select all images from a folder inside the output folder. (Not recursively.)

So... As you can see from the screenshot the images are split based on their resolution.
It's also not possible to edit dynamically the number of outputs, so I just picked a number : 4.
The node will separate the images based on their resolution, so with this node you can have 4 different resolutions per folder. (If you have more than that, maybe you should have another folder...)
To avoid error or crash if you have less than 4 resolutions in a folder, the node will just output white tensors. (white square image.)
So this node is a little hacky for now, but i can select my different characters in less than a second.
If you want to know how i personnaly save my images for a specific character, here is part of my workflow (Notice that i personnaly use / for folders because I'm on linux) :

In this example I put "character/" as a string and then combine with "nothing". But it's the same if you do "character" and then combine with "/". (I just like having a / at the end of my folder's name...)

If you are satisfied with this logic, you can then select all these nodes, right click and Convert to Group Node, you can then have your own customized "save character node" :

Here is another example of the same thing but excluding the save folder node :

⚠️ If you really want to regroup all the images in one flow, you can use my node 47 Combine images to put them all together.

44 - 🖼👈 Select an Image, Pick

Description:
Select an image from a list of images.

Useful in combination with my Load images from folder and preview image nodes.

You can also of course make a group node, like this one, which is the same as the screenshot above :

45 - 🔀 If-Else (input / compare_with)

Description:
Complex logic node if/else system.

If the input given is equal to the compare_with given in the widget, it will forward send_if_true, otherwise it will forward send_if_false. (If no send_if_false it will return None.)
You can forward anything, below is an example of forwarding a different size of latent space depending if it's SDXL or not.

Here is an example of the node with all outputs displayed with Show text nodes :

send_if_false is optional, if not connected, it will be replaced by None.

If-Else are chainables, just connect output to send_if_false.
⚠️ Always simply test input with compare_with, and connect the desired value to send_if_true. ⚠️
Here a simple example with 2 If-Else nodes (choose between 3 different resolutions).
❗ Notice that the same write text node is connected to both If-Else nodes input :

Let's take a similar example but let's use my Write loop text node to display all 3 types once :

If you understood the previous examples, here is a complete example that will create 3 images, landscape, portrait and square :

Workflow is hidden for simplicity, but is very basic, just connect latent to Ksampler, nothing special.)
You can also connect the same advanced loop write text node with my save folder node to save the images (landscape/portrait/square) in separate folders, but you do you...

46 - 🖼🔍 Image Details

Description:
Display the details of an image. (width, height, has_transparency, orientation, type)
RGBA is considered as having transparency, RGB is not.
orientation can be landscape, portrait or square.

47 - 🖼🔗 Combine Images

Description:
Combine multiple images (A single image or a list of images.)
If you want to merge several images into a single image, check node 60 or 61.

There are two types of logic to "combine images". With "all_in_one" enabled, it will combine all the images into one tensor.
Otherwise it will send the images one by one. (check examples below) :

This is an example of the "all_in_one" option disabled (Note that there are 2 images, these are NOT side by side, they are combined in a list.) :

But for example, if you want to use my node select an image, pick, you need to enable all_in_one and the images must all have the same resolution.

You can notice that there is no visible difference when you use all_in_one with preview image node. (this is why I added the show text node, note that show text will make it blue, because it's an image/tensor.)

When you use combine image node, you can actually also send many images at once, it will combine them all.
Here is an example with Load images from folder node, Image details node and Combine images node. (Of course it can't have all_in_one set to True in this situation because the images have different resolutions) :

Here another simple example taking a few selected images from a folder and combining them (For later processing for example) :

48 - 🔀🎲 Text scrambler (🧑 Character)

Description:
Take text as input and scramble (randomize) the text by using the file scrambler/character_scrambler.json in the comfyui custom nodes folder.

49 - 📹👁 Video Preview

Description:
This node takes a video path as input and displays the video.

50 - 🖼➜📹 Images to Video path (tmp video)

Description:
This node will take a list of images and convert them to a temporary video file.
❗ Update 0.50 : You can now send audio to the video. (audio_path OR audio TYPE)

51 - 📹➜🖼 Video Path to Images

Description:
This node will take a video path as input and convert it to a list of images.

In the above example, I also take half of the frames by setting frame_interval to 2.
Note that i had 16 frames, on the top right preview you can see 8 images.

52 - 🔊📹 Audio Video Sync

Description:

This node is an overengineered node that will try to synchronize the duration of an audio file with a video file.
❗ Video ideally needs to be a loop, check my ping pong video node if needed. The main goal of this synchronization is to have a clean transition between the end and the beginning of the video. (same frame)
You can then chain up several video and they will transition smoothly.

Some details, this node will :

• If video slightly too long : add silence to the audio file.
• If video way too long : will slow down the video up to 0.50x the speed + add silence to the audio. (now editable)
• If audio slightly too long : will speed up video up to 1.5x the speed. (now editable)
• If video way too long : will speed up video up to 1.5x the speed + add silence to the audio.

It is good like for example with MuseTalk https://github.com/chaojie/ComfyUI-MuseTalk

Here is an example of the Audio Video Sync node, notice that it is also convenient to recover the frames per second of the video, and send that to other nodes. (Spaghettis..., deal with it. 😎 If you don't understand it, you can test it.) :

❗ Update 0.50 : audio_duration is now optional, if not connected it will take it from the audio.
❗ Update 0.50 : You can now send the video with a list of images OR a video_path, same for audio : AUDIO or audio_path.

New v0.50 layout, same logic :

53 - ♻ Loop Load checkpoint (Model Selector)

Description:
This is the loop version of node 41. (check there for similar details)
It will loop over all the selected checkpoints.

❗ The big difference with 41 is that checkpoints are preloaded in memory. You can run them all faster all at once.
It is a good way to test multiple checkpoints quickly.

54 - ♻ Loop Lora Selector

Description:
Loop over all the selected Loras.

Above is an example with Pony and several styles of Lora.

Below is another example, here with flux, to test if your Lora training was undertrained, overtrained or just right :

55 - 🎲 Random Lora Selector

Description:
Just take a single Lora at random from a list of Loras.

56 - ♻📑📝 Loop Sequential (Integer)

Description:
This loop works like a normal loop, BUT it is sequential : It will run only once for each workflow run !!!
The first time it will output the first integer, the second time the second integer, etc...
When the last is reached, the node will STOP the workflow, preventing anything else to run after it.
Under the hood it is using a single file counter_integer.txt in the ComfyUI/Bjornulf folder.
❗ Do not use more than one node like this one in a workflow, because they will share the same counter_integer.txt file. (unexpected behaviour.) Update 0.57: Now also contains the next counter in the reset button.

57 - ♻📑 Loop Sequential (input Lines)

Description:
This loop works like a normal loop, BUT it is sequential : It will run only once for each workflow run !!!
The first time it will output the first line, the second time the second line, etc...
You also have control of the line with +1 / -1 buttons.
When the last is reached, the node will STOP the workflow, preventing anything else to run after it.
Under the hood it is using the file counter_lines.txt in the ComfyUI/Bjornulf folder.

Here is an example of usage with my TTS node : when I have a list of sentences to process, if i don't like a version, I can just click on the -1 button, tick "overwrite" on TTS node and it will generate the same sentence again, repeat until good.
❗ Do not use more than one node like this one in a workflow, because they will share the same counter_lines.txt file. (unexpected behaviour.)

Update 0.57: Now also contains the next counter in the reset button.
If you want to be able to predict the next line, you can use node 68, to Add line numbers.

81 - 🔥📝🖼 Image Text Generator 🖼📝🔥

Description:
Main node to generate content, doesn't really do much by itself, just camera angle and multicharacter action. (For example : ... eat picnic, view from above.)
BUT, you can connect others Text Generator Nodes to it.

⚠️ Warning for "Text Generator" : This node is JUST writing text, text is then interpreted by a checkpoint (SD1.5, SDXL, Flux...) to generate an image.
Some models are very bad at doing some things, so DON'T EXPECT for everything you do to work properly all the time with every checkpoints or loras. (This node was made with FLUX in mind.)

Below is a Tutorial on how to use all my Text Generator nodes. I did that small tutorial in 8 steps:

Step 1 : You use the main Text Generator node, it will write general details about the image (here camera_angle and shot_type) - For now I just combine the text to a simple "write text" that will send swamp monster :

Step 2 : Add a specific style to your image :

Step 3 : Add scene/background to your image :

Step 4 : Add a character to the scene using a character node, instead of the Write text Node.
I will remove the "swamp monster" from the "write text node" and use my Character Node instead, I will use it to create an agressive dragon with lighting powers :

Step 5 : Character nodes (Male/Female and creatures) can contain more than one character. (But they will share the same characteristics)
Below I removed the dragon and I created 2 "Character male" fighting by using the multi_char_action from the main node. (You can set it to CUSTOM and write your own action too.)

Step 5 : Let's try to add a location for the character, I want to put it on the left of the image. Here is a failure with the SDXL model I have been using all along :

Step 6 : Switch to FLUX to test the location_on_image feature (which is working) :

Step 7 : Switch to API black Forest Lab with FLUX Ultra, using my API custom node 109.
If you want several characters with different characteristics (like location_on_image or whatever), you can chain several Character Nodes together by connecting them to each other.
You can see below that I asked for 2 tiny dragons on the left and a zombie on the right.

Step 8 : And to end this tutorial, I will disable the Zombie, I will add an outfit (here a floral armor), I will also add a pose node for the character and also connect this pose node to an object node. (They will together make the character hold a book and put his hand on chin)

Below is an example with a grid of 6 images, it will split them into 6 separate images (3 rows X 3 columns) :

Why do I need that ? Sometimes I have several characters in a single image/video.
When I want to apply lip sync to a character, I need to split them into separate images/videos where4 the character is located, create the lip sync, and then reassemble them with node 147.
Or just to save VRAM, by processing only the part of the image that I need.

147 - 🖼📹🔨 Reassemble Image/Video Grid

Description:

Reassemble an image/video that was grid split with node 146.
Will need to take the same grid size as input.

You can apply changes to a specific element of the grid, and then reassemble them.

You can select each part individually.
But there is also a "special" part, the MODIFIED one.
This part is selected with the MODIFIED_part and the MODIFIED_part_index (part number, if index set to 2, it will use part_2).

Below is an example where I modify part_2 and reassmbling it. (Without using part_2 output but selectionning it using 2 as MODIFIED_part_index) :
You can also work directly with part_2, but twith this setup you can quickly switch in between parts without changing the node layout.

Below is an example where I show you that you can also influence different parts "manually". (Here, I just send part_1 to replace part 7,8,9.)

For reassembling videos it might get tricky.
For example if you used the node 52 - 🔊📹 Audio Video Sync, the modified part might be shorter/longer, change FPS etc...
You can try to re-synchronize them all if the duration was modified.
In this situation you need to use the reference_video_part_index to select the reference video part. (Probably the same as the MODIFIED_part_index.)

148 - 💾🔊 Save Audio (tmp_api.wav/mp3) ⚠️💣

Description:

Temporary save for an audio file, mp3 or wav.
Useful if you want to synchronize data in between API calls from several Comfyui instances. (Used in the background by my API nodes, like node 157 🔮⚡ Execute Workflow, to exchange audio files. - raw/processed -)

You can send audio_path (This will create file tmp_api.mp3) :

Or an AUDIO type (This will create file tmp_api.wav) :

Note that if you are sending an AUDIO type, this node will save it as a wav file. (Even if your selection is an mp3 file.)

149 - 💾📹 Save Video (tmp_api.mp4/mkv/webm) ⚠️💣

Description:

Temporary save for a video file, mp4, mkv or webm.
Useful if you want to synchronize data in between API calls from several Comfyui instances. (Used in the background by my API nodes, like node 157 🔮⚡ Execute Workflow, to exchange video files. - raw/processed -)

150 - 🎨📜 Style Selector (🎲 or ♻ or ♻📑) + Civitai urn

Description:

A new Universal node for selecting styles.
Also contains some informations for Civitai urn. (Need test and better "database" of good/fast models, i recommended you to send the urns you like manually.)

Here is an example of usage with CivitAI API node :

Here is a slightly more complex example using model urns :

NOTE : CivitAI can be particularly slow !! So you can use the option DO_NOT_WAIT instead with an optional "links_file".
It will create a file with the links to recover the generated images later with the node 151.
So you can make as many requests as you want, and come back another time to recover the images with this txt file.

Note that you can also send the LIST directly with all the values.

If you do that you can later recover the values like text and use the "autosave" option of node 151.
It will take the style and make a folder for it. Example from the image above : ./ComfyUI/output/civitai_autosave/Cinematic_photography/
It is very useful if you use node 150 as a LOOP, you can recover the images later and organise them automatically in separate folders according to the selected style.

151 - 📥🕑🤖 Load CivitAI Links

Description:

This node must be used after using the node 150 + DO_NOT_WAIT + links_file.
When saving DO_NOT_WAIT and the "links_file" from the node 150, it will create a txt file in "ComfyUI/Bjornulf/civitai_links/", you can load them with this node.

Below are the images recovered from the file "11_mars.txt":

If you used from node 150 the LIST_from_style_selector you can later recover the values and use the "autosave" option of node 151.
It will take the style and make a folder for it. Example from the image above : ./ComfyUI/output/civitai_autosave/Cinematic_photography/
It is very useful if you use node 150 as a LOOP, you can recover the images later and organise them automatically in separate folders according to the selected style.

152 - [Coming soon] 💾 Save Tensors (tmp_api.pt) ⚠️💣

Description:

This is BETA, it will save a tensor in a file.
The goal is to optimize the VRAM usage by saving tensors in files.

153 - [Coming soon] 📥 Load Tensor (tmp_api.pt)

Description:

This is BETA, it will load a tensor.
The goal is to optimize the VRAM usage by saving tensors in files.

154 - 🔮 Remote VAE Decoder

Description:

Simple node to decode a VAE model from a remote machine.

The VAE decode node doesn't have to be on the same machine, so if you have a remote machine and want to save the VRAM, you can use that.
The remote machine need to have my custom nodes too.

155 - [Coming soon] 🔮 Remote VAE Decoder (Tiled)

Description:

Same as 154 but with tiled version.

156 - [Coming soon] 📥🔮 Load from Base64

Description:

This is BETA, it is used to recovered some values between Comfyui instances.

157 - [Coming soon] 🔮⚡ Remote Execute Workflow

Description:

This is the start of a complex new environment and this is in BETA.
The goal of this node is to run a workflow on another Comfyui instance and recover what was generated.
For now it supports image/sound/video.

It can do anything that a normal workflow can do.
Create an image, create a video, upscale an image, etc...

I will share custom JSON and a lot more cool stuff for my Kofi supporters. (https://ko-fi.com/bjornulf)
Keep in touch for more informations... Wip...

Basically use run heavy duty workflows on another machine, and recover the results.
Below is an example of a lipsync workflow that I run on another Comfyui instance. (For now local network only, but will run on runpod too.)
I use that on my laptop (192.168.1.23), that recovers the results from my "ai dedicated" desktop machine (192.168.1..100) :

158 - [Coming soon] 📥🔮📝 Text Manager Api (Execute Workflow)

Description:

This is BETA.
This node need to be used to create functional workflows to run with node 157.
It is communicating with node 157 from another Comfyui instance.

159 - [Coming soon] 🔥📝📹 Video Text Generator 📹📝🔥

Description:

This is BETA.
This is the start of a new node that will generate a video prompt.
It's goal is to be like the "Text Generator" node, but for videos.

160 - 🦙👁 Ollama Vision Prompt Selector

Description:
New layout prompt selector for Ollama Vision.
Ollama vision is now divided in 2 separate nodes.

161 - [Coming soon] 🔧🧑 Fix Face

Description:

This is BETA.
First node of a new collection of "Fix Images" nodes.
Quickly fix, control and edit faces. (and more)

Here is a zoom of that :

You can also give specific text and custom denoise for each faces :

You can also select a specific face, if set at 0 it will do all the faces, but below I set it to 1 :

This node can also fix the whole person, but i will likely make another separate node for that later :

You can preview the nodes effects very well with my Preview Image node, You can clearly see here the white box that is the detected "person" :

In the future I will make a system to "inject" a specific reusable character, probably connected to loras or suchs.
