Use stable diffusion via comfyUI inside Nuke. Tutorials and proper documentation will follow.

Use

I'm providing 3 basic workflows templates as examples. Workflows must have a "translation.py" to work inside nuke (check Workflows folder)

1. Open Nuke

2. Press Tab and create comfyUI_Nuke toolset

3. Setup the settings tab with your server address and disk folder:

   Default server: http://127.0.0.1:8188 Directory: /wherever/you/installed/ComfyUI/

4. Save the toolset with your defaults.

Errors

Error	Causes
[Errno 61] Connection Refused	ComfyUI is not running or wrong network address
[Http Error 400 or 40X] Bad Request	The workflow .json file has something incompatible on it. Usually your system has a checkpoint that has another name, ".safetensors" instead of ".ckpt" for example. ComfyUI terminal will tell you which parameter is wrong. Drag the workflow from the "ComfyUINuke/Workflows" folder into ComfyUI, fix the issue and save the workflow file overwriting the problematic one. Do not forget to always save the files with "Save (API format) " (ConfyUI > Settings > Enable Dev mode Options)
RuntimeError: /users/youruser/.nuke/comfyUINuke/toolSets/comfyUI_Nuke.nk is for nuke15.0v1; this is nuke14.1v4	Open and Save comfyUI_Nuke.nk in whatever Nuke version you use
