Hi....still very new to Octane and can't seem to find a solution. Maybe it's right before my eyes and I don't see it.
I'm trying to make an object have it's own alpha channel. I can use the material ID layer but I never really get a clean selection from that in Photoshop. Close but not real crisp. I'd love to be able to turn all black and only the one I want white. Any way to do that?
Also, how can I completely turn off an object from rendering. I can turn it's opacity to '0' but the shadow still renders and I am unable to select 'through' the '0' opacity object to the object behind. The '0' opacity object seems to still leave behind a 'ghost'.
TIA
