Hello,
I am at a loss as to why this is not possible. In the attached screen grab is my simple scene, where I am attempting to make the RC object conform to the terrain surface. However, it will not allow me to pick it. It has something to do with the fact that the terrain uses a VRayDisplacementMod and a VRayDistanceTex. If I disable one or the other, I can pick the surface. What is causing that?
I suppose as a workaround I can duplicate the terrain and hide it, then use the duplicate as the conform surface. But would prefer not to.
