PBR Material icon not showing

[medallion_builders]

Hi,

I am using Vray 5.00.02 and cannot find the PBR material icon. What am I missing?

Hi medallion_builders,

The PBR material can no longer be created in V5.
It has been merged with the Generic / VRay Mtl.

The Metalness parameter is located in the Reflections rollout.
There is also a parameter called Surface Control that lets you switch between Glossiness and Roughness for Reflections and Refractions.


There are a couple of reasons that pushed us in that direction:

1. User started requesting more and more parameters to be added to the PBR material (Refractions, Anisotropy, etc.). We realized that we'll have to replicate 90% of the VRay Mtl UI for the PBR which was defeating the purpose. It just made more sense to merge them.
2. There is only one shader in V-Ray Core and keeping one shader in the UI is just easier to maintain.
3. There is no standard PBR set of parameters or workflow. Some PBR workflows require Base Color, Metalness and Roughness maps, others Base Color, Metalness and Smoothness (Glossiness), others Diffuse Color, Specular Color, Roughness, etc. And the new unified shader lets you use any approach you like.

Hope that makes sense,
Konstantin
