Hi
First, your version of V-Ray is somewhat old-ish. I recommend you update to the latest 4.20 for free. (this won’t fix your problem here, but contains a lot of fixes and features)
The Bricks Simple 05 is one of those materials that will display black. Its diffuse texture is a V-Ray procedural tiles texture, not an image file.
Rhino does not understand V-Ray procedurals and V-Ray does not understand Rhino procedurals either.
So basically there is nothing to display. The black color you see is the color of the diffuse slot, that is “bellow” the texture. You can change the color as you like, it is not used by V-Ray since there is a texture atop, so your material does not show black in the viewport
Alternatively you can bind a “viewport texture” - a bricks image of your choice, or any other image file. The viewport texture binding is used specifically for this kind of situations
V-Ray will still render the material as it is set, the binding is just for viewport display
We’re working on auto-bake solution for procedural textures that will use V-Ray itself to generate visually correct image from the diffuse slot, and use that image as viewport representation.
This will be available in the near future
