  • Displacement doesn't work with VrayTriplanarTex?

    I'm trying to make displacement work with VrayTriplanarTex map, but I'm not getting good results. Please see the screenshot below. I'm using the VrayDisplcementMod modifier with 3D mapping mode. Is the triplanar map not supported by GPU when used for displacement? The VrayTriplanarTex page and the GPU supported features page in the help docs doesn't seem to point out any restrictions.

          Thanks, Muhammed_Hamed ! BTW, it seems that the stochastic tiling feature in VrayUVWRandomizer map doesn't work with GPU displacement too. Probably same issue.
