# ComfyUI-Krea2-MultiRef (temporary README)

ComfyUI custom nodes for Krea2-style multi-reference image editing.

## Nodes

- **Krea2 Model Patcher** — patches a Flux diffusion model to consume reference latents during sampling.
- **Krea2 Reference Text Encode** — encodes a prompt together with up to 4 reference images through the Krea2 Qwen3-VL text encoder. Connect a VAE to also attach reference latents.
- **Krea2 Reference Encoder (latent only)** — attaches pre-encoded reference latents to conditioning without re-encoding text.
- **Krea2 Diagnostic** — prints diffusion model internals for debugging.

## Quick start

1. Place this folder under `ComfyUI/custom_nodes/`.
2. Restart ComfyUI.
3. In a workflow:
   - Load your Flux model.
   - Add `Krea2 Model Patcher` and connect the model.
   - Add `Krea2 Reference Text Encode`, connect CLIP + VAE + reference images, and write your prompt.
   - Feed the patched model and conditioning into a KSampler as usual.

## Requirements

- ComfyUI with Krea2/Qwen3-VL text encoder support.
- `einops` (usually already installed with ComfyUI).

## Notes

- Reference images are downscaled to a max of 512×512 pixels for the VLM.
- Reference latents are capped at 1024×1024 pixels and snapped to multiples of 16.
- This README is a placeholder and will be expanded.
