Please add Energy Conservation on Refractive materials.

More than those 3 automatic previewing options possible (Face Skipping, Refined Clustering, Vertex Clustering ). being able to create one's own simple preview (for furniture, any objects... event buildings)

such as any cosmos proxy asset.

Corona had released a Fabric Material in Corona 14, its really neat and it will be very helpful to have it in V-Ray too. Please consider to integrate in next update.

A dedicated Tiles generator like Bercon Tiles/Corona Tiles but built for V-Ray, Compatibility with BerconGradient or dedicated gradient map to create more complex tiles

Pretty sure you can do much better work than MAX and Corona.Features from MAX Color Correction + LUT and Curves from Corona Color Correct + Correction per Color channels

In Chaos Cosmos, the materials section displays Chaos Scans materials at the top of the list. For users who do not have a Chaos Scans subscription, this is inconvenient, because those materials cannot be used. Since I am not currently subscribed t...

The blurry reflections and refractions in the material editor (both compact and Slate) can be very noisy, especially when viewing an enlarged shader ball. The increased noise makes it difficult to evaluate small noise bumps and overall shader qual...

vray does not allow to send render to cloud when a production rendering is already active. I think this can change with new version.

those .vrscene can be purchased at Maxtree for example. Simple but very crucial workflow point. Without this possibility (of scattering), Rhino users (like me) need to dowload fbx versions instead, and set all texture maps and setting propoerly fo...
