ComfyUI-Otacoo

ComfyUI custom nodes for loading checkpoints and LoRAs with model image previews in the selector.

Nodes

Checkpoint Loader 🔰

• Loads a checkpoint (MODEL, CLIP, VAE) just like the built-in loader.
• Optional separate VAE: Choose “default” to use the checkpoint’s built-in VAE, or pick another VAE from your models/vae folder.
• Preview grid: Select your model using a grid with preview images.

Unet Loader 🔰

• Loads a UNet model (safetensors) just like the built-in loader.
• Preview grid: Select your model using a grid with preview images.

LoRA Loader 🔰

• Apply any amount of LoRAs in one node, each with its own model strength and toggle.
• Preview grid: Select your model using a grid with preview images.
• Trigger Words: Extracts and outputs each LoRAs trigger words by reading .json or .metadata.json files.

Global Sampler 🔰

• Globally set the sampler and scheduler for all nodes in the workflow.

Preview images

Previews are loaded from ComfyUI’s model folders (same folder as the model file). Place an image next to the model with the same base name:

| Model file | Preview file (any of these) | |------------|----------------------------| | example.safetensors | example.preview.jpg, example.png, etc. |

Names checked (first match wins):
<basename>.preview.png, .preview.jpg, .preview.jpeg, .preview.webp
<basename>.png, .jpg, .jpeg, .webp
