Transparent Material blend / Fog color issue

[begem0t]

I'm probably missing something here, but I can't think of a way to blend 2 brdf materials that have Fog Color.

Blend Material works with base material/coat materials, so materials are not equal and adding transparency mask is not doing what I would like.

The problem seems to be in the way Fog Color works - it cannot be softly blended to transparency even in a normal VrMaterial.

The attached example works because one of the materials is not transparent. How to expand this to transparent materials?

Hello begem0t and sorry for the really late reply. This is a known limitation. You can try using V-Ray ScatterVolume to "fill" the transparent object and play with it's settings, won't be perfect solution but it can work for you. Both meshes shouldn't be overlapping perfectly, otherwise one of the objects won't be rendered. A Peak sop on inside object with really small negative value should fix the problem.
