Vray Plane and Geometry Displacement

[onesee]

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.

Its a bit early in the morning for me, but here is my logic: The vray plane is supposed to be infinately big in all directions. When you add displacement in your scene, usually the render takes quite a while to calculate the new geometry. If you added a displacement on your vray plane, the render would basically take forever since it calculates the displacement on a plane that goes on forever. Also the vray plane does not have any segments. This could be the reason it does not work, but i dont know for sure.

"VRayDisplacementMod has no effect on VRayPlane objects, VRayProxy objects or VRayFur objects."

Thanks for confirming it Ismael. This is also true in material editor, a shame that vrayplane doesn't seem to take on any z depth property.
