Hi
Changes to material types inside VRayBlendMtl and VRayBumpMtl does not seem to be recorded when using state sets. For example if the materials inside those were originally VRayMtl, and I then change them to VRayLightMtl, this change is not recorded.
If I have a MultiSub Material that contains VrayMtl, and I change those to VRayLightMtl, then that change IS recorded. This makes me believe something is wrong (or not yet supported) when using VRayBlendMtl and VRayBumpMtl
