sn0w-scripts

A collection of nodes and improvements created mainly for testing loras and general ease

Get Started

Install

1. Install ComfyUi.
2. Clone this repo into custom_nodes:

   cd ComfyUI/custom_nodes
   git clone https://github.com/sn0w12/ComfyUI-Sn0w-Scripts
   

3. Start up ComfyUI.

Important Note

Many of the nodes require these paths to be in your extra_model_paths.yaml (with your real directories of course).

• loras_xl: C:/path/XL
• loras_15: C:/path/1.5

Nodes

Find Resolution

An easy way to select a width and height.

ℹ️ See More Information

• Enable flip if you want to swap the resolutions

Lora Selector

Automatically selects X amount of loras between two numbers.

ℹ️ See More Information

• Loras have to be formatted like the default kohya_ss outputs. (lora_name-000001)
• Select the first lora.
• Select the number of the highest lora you want to test.
• Select the amount of loras you want to test.
• Outputs list of loras like this: <lora:name:strength>
• Add default generation adds an extra "nothing" at the end of the list, used in Lora Tester to generate an image without the lora.

Lora Tester (XL)

Automatically generates X amount of images with provided loras.

ℹ️ See More Information

• I recommend making lora_info and add_default_generation inputs and using the outputs from the Lora Selector.
• Takes normal KSampler input but takes positive and negative inputs as text.
• Outputs a batch of images.

Character Selector

Outputs a character name and prompt.

ℹ️ See More Information

• Loads characters.json and outputs prompt based on it.
• Note: Currently very small list, feel free to add your own to the json file.

Prompt Combine

Combines 4 string to a single string.

ℹ️ See More Information

• Combines 4 strings into one with a seperator, but only adds the seperator of there isnt one already at the end of the string.
• Removes any duplicate words.

Lora Stacker

Outputs a list of loras for Lora Tester.

ℹ️ See More Information

• Basically Lora Selector but manual.
• Specifically for the lora testers.

Load Lora XL/1.5

Normal load lora but from another folder.

ℹ️ See More Information

• Add these to your extra_model_paths.yaml (for example):
• loras_xl: C:/path/XL
• loras_15: C:/path/1.5
• Shows an alphabetically sorted list.

Load Lora Character

Finds and applies the closest matching Lora model to a character based on name similarity.

ℹ️ See More Information

• The process begins by cleaning the input character string for comparison. It then searches a JSON file for a matching character name. If a match is found, it proceeds to select the appropriate folder based on the xl boolean flag.
• To find the closest Lora model, it calculates the Levenshtein distance between the character name (in full and in parts) and the filenames of available Lora models. This ensures a case-insensitive match with the best possible model.
• If no lora is found it just returns the input model and the workflow can continue.
