Have you tried Vray for Blender? What are your thoughts on using it?
The information on Vray for Blender is scarce at the moment, so I am hoping for a little bit more information on the subject.
I reckon Vray for Blender has proxy support and most of the settings seem familiar to what’s available in Vray 3ds Max or Rhino. However, seeing as how it is a stand-alone integration, does it have a real-time rendering solution in the viewport (like activeshade)?
