Cryptomattes Question

[timot.mo]

Is it possible to have some geometry show up on the cryptomatte EXR file but not in the actual render itself?

Thanks!

Hi,
you can sett the Kernel to 1 Max Samples, in this way the Beauty render time will be almost zero, and only active Auxiliary/InfoChannel AOVs will be rendered.
You can also avoid to save the Beauty, to save only Cryptomatte AOVs.

ciao,

Thank you, yeah that's what I've been essentially doing. Would be nice if they added to the octane object tag a way to streamline all this so we only have to perform one render.

You idea is not clear, but it's not a thing that you can do by adding some tag or so. Scene data should be send and having a main render or not that will not accelerate anything. Keep going with maxsamples=1 method. Nothing is better.
