Hi,
it seems the distance texture is not affected by displacement (through VRayDisplacementMod). I’m not 100% sure, but wasn’t that working before?
Since the VRayDisplacementMod subdivision is done after the VRayDistanceTex evaluation, so V-Ray historically doesn’t support it.
Try using 3ds Max’s Turbo Smooth and Displacement modifiers instead of VRayDisplacementMod.
(VRayDistanceTex evaluates the viewport mesh.)
Oh alright, thx. I somehow had in memory that it would calculate the distance during rendertime, so after the displacement. Bummer…
