ComfyUI-ApplyResAdapterUnet

ComfyUI node to apply the ResAdapter Unet patch for SD1.5 models.

See https://github.com/bytedance/res-adapter for explanation and link to download the LoRA and unet patch.

Note: I am not affiliated with ResAdapter. This is an (experimental) personal project. I believe it works correctly, but no guarantees!

Usage

SDXL

For SDXL, you only need the LoRA (as far as I know) so a dedicated node is unnecessary: just load the LoRA as usual. You don't need this repo.

SD 1.5

  • Put the resolution_normalization.safetensors model in models/unet
  • Patch the model with the ApplyResAdapterUnet node, load the resolution_lora.safetensors LoRA normally.

Node example

You can experiment with different unet and LoRA strengths. I haven't tested it extensively, but at resolutions above 1024x1024 using full strength doesn't seem to work well (and in fact may be worse than nothing). It's also possible to combine ResAdapter with other techniques such as Kohya Deep Shrink (AKA PatchModelAddDownScale).
