Available Nodes

LoRA Loader (by Index)

Loads a LoRA by its numerical index in your sorted loras folder.

Inputs

• model: The base model to apply the LoRA to
• index: The numerical index of the LoRA in your alphabetically sorted loras folder
• lora_list: A dropdown showing all available LoRAs (the selection is visual only, the index determines which one is loaded)
• strength_model: The strength to apply to the model part of the LoRA
• strength_clip: The strength to apply to the CLIP part of the LoRA
• clip (optional): The CLIP model to apply LoRA to (if applicable)

Outputs

• MODEL: The model with the LoRA applied
• CLIP: The modified CLIP model (if provided)

LoRAname (by Index)

Returns a LoRA filename selected by index from a list of user-defined LoRA names. This can be connected directly to a standard "Load LoRA" node.

Inputs

• index: The numerical index to select from the LoRA names list
• LoRAnames: Multiline text input with one LoRA filename per line

Outputs

• lora_name: The selected LoRA filename, compatible with the standard "Load LoRA" node

Trigger Words (by Index)

Returns a text string selected by index from a list of user-defined trigger words or phrases.

Inputs

• index: The numerical index to select from the trigger words list
• triggers: Multiline text input with one trigger word or phrase per line

Outputs

• STRING: The selected trigger word or phrase

Example Workflows

Basic Index Selection

1. Load a base model with a checkpoint loader
2. Connect the model to the "LoRA Loader (by Index)" node
3. Set the index to select a specific LoRA (e.g., 0 for the first LoRA alphabetically)
4. Adjust strength_model and strength_clip as needed
5. Use the output model for your image generation

Dynamic LoRA Selection

1. Create a "LoRAname (by Index)" node
2. Enter your desired LoRA filenames in the multiline text field
3. Connect its output to a standard "Load LoRA" node's lora_name input
4. Change the index to dynamically select different LoRAs
5. Connect your model and adjust strength as needed

Using Trigger Words

1. Create a "Trigger Words (by Index)" node
2. Enter your trigger words/phrases in the multiline text field
3. Connect its output to a text input in your workflow
4. Change the index to dynamically select different trigger words
