New Render Channel - Bump
Posted: Wed Jan 05, 2011 4:04 pm
The roughness and Fresnel channels don't seem to have much use in post processing, but may have some validity when it comes to checking those particular aspects of an overall scene.
I'd like to see something similar in the form of a Bump channel.
Basically it would be a clay render (all material textures/colors are substituted with a neutral gray tone, opacity and transmittance would stay in tact and emitters would be unaffected). The only difference would be that the bump and displacement would remain intact. I think this would be a nice 'check' as sometimes bump can look okay in a small preview but in an overall scene turns out to not be quite right.
Presumably, by overlapping a Reflection channel, you could also get the bump and reflections without the texture maps which may also be handy.
