What is comfyui-krea2-reference?

ComfyUI-Krea2-Reference is a custom add-on node for ComfyUI, a visual tool for building AI image generation workflows. It works with an image model called Krea 2, and it lets you feed in reference pictures so the model can copy a character's look from one image and a painting style from another, then combine them, similar to telling an AI "draw the character from picture one, in the art style of picture two." Normal image editing tools often just paste or blend reference images together, which can look collaged and unnatural. This node instead feeds the reference images into the model as part of its internal understanding of the prompt, the same way it was originally trained to read images, so the result looks like a single coherently generated picture rather than a copy-paste job. Paired with a companion add-on called a reference LoRA, a small file that adjusts the model's behavior, the tool follows your written scene description more closely instead of just recreating the reference images. The main node lets you supply a text prompt along with up to four reference images, labeling each one as either a character reference or a style reference directly in your prompt text. You can control how much visual detail each reference contributes, crop a reference to a specific area, and remove backgrounds automatically. A second node loads the reference LoRA file and lets you tune how strongly it influences the results, with a recommended default setting described as producing the most reliable character likeness. The README notes some current limitations: using a reference sheet with multiple views of the same character can accidentally produce multiple views in the output, and combining both a character reference and a style reference in one prompt only works partially for now. A future version is described as in progress to address these. To install it, you clone the repository into ComfyUI's custom nodes folder, then download the required model files and the reference LoRA separately.
