Can not convert PBR material into vray material

I find this wood material on food4rhino
ash olive - Olivesche | Food4Rhino

I try convert into vray material in order to render. But it not work.
Need advice



The material in question is not a PBR material - it is normal generic Rhino material.
The actual problem is that the diffuse texture is procedural. In this case Rhino samples the texture at w=0, and we get a 2D (U,V)-space image file to use for rendering. V-Ray ignores the W coordinate of the mapping channel, since the input source is a 2D image (no W data)
