Krea 2 Character Forge

* Please read the description carefully before asking any questions *

Part One : Base

This is a Krea 2 workflow featuring a custom node I made to inject character traits directly into the prompt and generate a clean, detailed character base image.

Using these custom nodes is basically like creating a character in an RPG video game , you can define, mix, and customize different character traits to build the character you want.

The generated image can then be used as a reference for the Character Sheet / Dataset Generator, the second part of the process. It takes the character you create here and generates a diverse set of images designed for character LoRA training.

I intentionally kept the two workflows separate instead of combining everything into one huge spaghetti workflow. This keeps each workflow focused and gives you the flexibility to use any other reference image with the Character Sheet Generator rather than being limited to characters created with this workflow.

How to Install the custom node :

1. In your ComfyUI installation, go to: ComfyUI/custom_nodes/

2. Create a new folder called: character_trait_selectors

3. Download and Extract the custom node attached file inside that folder as: __init__.py

final path should be:

ComfyUI/custom_nodes/character_trait_selectors/__init__.py

4. Restart ComfyUI.

5. The nodes will appear under the "character_sheet/selectors" category

Loras :

I’ve also included a Stack LoRA Loader with suggested LoRAs, recommended strength ranges, and links to help improve character quality and identity.

However, if you want to use LoRAs to customize specific traits, it’s better to disable/bypass the related custom node input to avoid conflicting with the LoRA.

• Breast Size Slider

• Skinny/Fat Slider

• Waist Slider

• Weight Slider

• Age Slider

• Ass and Thighs Slider

• Skin Detail Slider

• Skin Tone Slider

For the best results, I recommend using trained Krea 2 checkpoints rather than the base Krea 2 Turbo model.

Part Two : Character Sheet Generator

This is the second half of the process. The Character Sheet Generator takes a character reference image and uses a set of pre-built prompts and custom nodes to generate a diverse batch of images featuring the same character across different poses, angles, conditions, and compositions.

The goal is to create a high-quality, consistent dataset for training character LoRAs, while keeping the character’s identity and appearance as consistent as possible across the generated images.

After testing the Krea 2 version extensively, I found that Krea 2 is unfortunately quite hit or miss when it comes to preserving the reference character. Based on my previous experience working with Flux Kontext, I decided to take it a step further and rebuild the same workflow using Flux Kontext. The difference was immediately noticeable, with Flux Kontext producing significantly better character consistency in my testing.

Because of this, I have also included a Flux Kontext version of the Character Sheet Generator, and I strongly recommend using it over the Krea 2 version. That said, feel free to test both workflows yourself and see which one works better for your particular character and use case.

If you are new to Flux Kontext, don't worry. The workflow includes links to the required Flux Kontext base model, CLIPs, and VAE, along with tutorials to help you get everything set up.

The workflow is designed to work with any character reference image, whether it was created using Part One or sourced from somewhere else.
