Inference

Inference: applies a .ocat model from a Train node to every frame (tiled, cached).

raw .md

Inference: applies a .ocat model from a Train node to every frame (tiled, cached). tile_size and overlap set the tiles (they blend over the overlap); mix blends the result with the input. Export writes TorchScript (Nuke CatFileCreator makes a .cat from it) or ONNX (Flame, Nuke 16+).

Nuke equivalent

No Nuke class. In a .nk file this node is written as an Oink node that Nuke will not recognise.

Train

Train (Nuke CopyCat / BigCat): connect before (Source) and after (Target) frames, list the frames, press Train.

ComfyUI

Run a ComfyUI workflow on this node's input (float EXR round trip).
