First public beta of DUGco AlphaGenSAM, a Nuke OFX plug-in that brings LTX-2.5 Alpha-Gen into Nuke through a Comfy backend.

  • Pick the object you want a matte of: type it, or Ctrl+click it in the viewer (SAM 3.1).
  • The LTX clean-plate IC-LoRA isolates it from everything else in the shot.
  • LTX-2.5 Alpha-Gen generates a clean alpha of just that object.
  • Run it on Comfy Cloud with your Comfy API key (no big GPU needed), or on your own local ComfyUI.
  • One node = one matte. Branch several nodes off one plate for several mattes.

Install (Windows): unzip, close Nuke, run install.bat, restart Nuke. Then open example/dugco_alphagensam_example.nk and set your Comfy API key from the node's Set API Key button. See the README for the Comfy Local model list.

Windows only for now. This is a beta, so please report issues.
