ZB 3.1 and Cinema 4D VRay Displacement?

ZBrush Usage Questions
#1

Has anyone had any luck with Displacement transferred from ZB to Vray 4 C4D?

I’m not getting much joy. I am getting displacements but it is messed up along the edges.

#2

Off hand, are you using any texture filtering such as mip-mapping or texture antialiasing? Have you tried offsetting the map slightly in the horizontal and/or vertical direction?

#3

Yes I do. I haven’t used DE3 for the disp map as I have no idea what to use.

ZB Settings:

Texture - GUV Tiles
Displacement


  • Adaptive On
  • DPRes 4096
  • Mode On
  • Intensity 0
  • Mid 50
  • Flipped Vertically with “Max” selected in the Alpha palette.
C4D VRay Settings:

Basic VRay material
UVW Mapping
Displacement


  • Sampling MIP
  • Blur offset/scale 0%
  • Amount 6cm
  • Shift (I’ve tried alsort here from -6 to 6)
  • Keep Continuity - tried it on and off
Thanks for the reply and I hope you can help.

#4

Do not use MIP mapping or texture antialiasing. Those features cause information to be pulled in from outside the UV regions, which is very apparent with a displacement map.

#5

Ok thanks.

I tried it without MIP mapping and it was the same, I don’t know where to disable texture AA within Vray though so I couldn’t try it without AA.

Do all my other settings look ok for use with Vray?
