Magic formula for making true MATTE holdout materials?
Posted: Wed Oct 20, 2021 4:56 pm
Has anyone figured out how to make traditional matte hold outs --"in camera"-- for rendering? In LW native we simply pick the mesh and tell it to be "matte and ignored by alpha" Thus giving us a true "black" cut-out and nothing in the alpha so that it, of course, doesn't show in the RGB as black.
I have tried all manner of things in Octane to achieve this and have not found a way.
UPDATE
Figured it out. Far simpler than I was making it out to be. Most likely how I missed it. Simple use the Shadow Catcher Material NODE. Set it's ENABLE to OFF. Done.
