Hi all - I've poked through as many threads as I can find regarding Real Displacement textures (rd-textures.com) and the proper setup for them. It seems like there is some conflicting info out there and some pre and post PDR workflow ideas too, which just add to the confusion for me. At this point I can get decent results, but I'm still wondering if I'm getting the best I can out of the textures.
Anyway, here's what I do with each map...maybe somebody who knows more than I do could critique? I'd be very grateful.
Basic settings:
IOR to 1.4 (based on forum posts I've seen)
Reflection Level to 1.0 (PBR workflow, right?)
Color Map > Diffuse slot
AO Map > Sometimes layered on top of Diffuse as a 'Multiply' layer if I want more contrast
Depth Map > Displacement slot (not a modifier, just plugged into the shader)
Roughness Map > Inverted and placed into the Glossiness slot
Bump Map > Bump Map
Normal Map > Ignore if using displacement?
Gloss Map (Low\Hi) > Ignore?
All maps have a gamma of 1.0 except Diffuse.
I also set all maps to a blur of .01, not sure if this is too sharp...comments on that would be great as well.
As for Displacement Height and Real World texture size I just go trial and error...not sure if there is guidance on that as well?
Anyway, sorry for all the questions - just trying to use these properly. Thanks!
Daniel
