No doubt vray is an industry standard for photorealistic rendering in CG world. Till now I had a feeling that Modo users were a little bit forgotten by Chaosgroup's crew. We have a promising signals from core developers of Vray that their flag product for Modo is going to be released sooner that anyone expected with really good support for Modo native features.
This is what I've found on Chaosgroup forum:
"Our integration is quite a bit deeper than what the Octane guys did... we've tried to support as many of the native Modo features as possible, including the shader tree, hair, we have also implemented the V-Ray proxies etc.
The core developer of V-Ray is Vladimir "Vlado" Koylazov. He even posted a screenshot of vray inside of Modo.
