Mental Ray no Preview in VIZ

[ivanjay]

Hi all,

 

Very frustrating problem that I cannot figure out. I am using Viz07 with mental ray renderer. I am creating materials in a variety of ways (maps, picking difuse color, etc.) However, some of these manterials are not showing in my camera view in Viz itself. I cannot manipulate map size and see my changes which means every time I change something I need to re-render, and guess at what I need to correct.

 

Any ideas why materials arent previewing?

 

Standard materials work just fine so I am sure it is a setting somewhere.

 

I do have mental ray as the assigned renderer.
