I have a test scene and playing around with vray plane. I can't seem to give it geometry in the material editor to create a infinite rough road to the edge of the horizon. I added a vraydisplacementmod and fiddle around with the settings but it does not show any displacement. I added the same parameter to a normal plane that shows it just fine, so my question is can Vrayplane inherit any geometry displacement? I could get it to show some deformation if I make it transparent and add in a noise map.
