Vray materials in the Modo OpenGL viewport

[jonmoore]

I'm aware that this has been brought up before and that Vray materials should at the very least be showing their diffuse colour in the Modo viewport but in 901 this doesn't seem to be the case as you can see in the test scene below. I wouldn't expect glass and metals to show up seeing as they have no diffuse information but the diffuse info for the laminate tiles and logo is missing too. As it happens this scene uses Modo 901 native PBS shaders for the curtain wall and the smoked glass at the back of the building and that's why those elements are visible in the OpenGL viewport.

I'm testing using the nightly build for Mac from 13/07/15 at the moment.

For the OpenGL viewport, even the diffuse color of the V-Ray materials won't show.
The MODO API doesn't support it. It has never worked.
The only workaround is to have a MODO native material below the V-Ray material, and use it for the viewport.

And by putting the Modo native material below the V-Ray material there are no conflicts or memory issues? I ask the question because V-Ray translates native Modo materials. Is it just a case that the V-Ray material masks out the Modo native one?

If there are no conflicts I can see a positive side to duplicating the scene materials (A/B testing Modo's native renderer to VRay). All the same it's a bit of a workflow killer. Really hope The Foundary open up the SDK for this kind of stuff.

As long as the V-Ray material is on top and has "Blend mode" set to "Normal" and "Opacity" set to 100 %, V-Ray will ignore the MODO material below it (or any material for that matter).
If you have texture layers (image maps for example) with effects set to some of the MODO material effects (for example "Specular amount"), those will get exported to the V-Ray scene, but won't be used during the actual rendering,
and since V-Ray loads the textures as they are needed, it shouldn't be a problem.
