Many of my students use Vantage for rendrering final animation and final rendering too, using V-Ray only to setup materials. 3DS Max users can install V-Ray without a license and use only Vantage for rendering. I have several students who would be interested in having the same workflow possibility for Rhinoceros and SketchUp, obviously installing V-Ray but without using the V-Ray Frame Buffer and without a license, using only the Vantage license. At the moment, this is not possible. I am asking if you can give Rhino and SketchUp users the ability to use Vantage connected to a working V-Ray without a license.
material editor and vrayscatter doesn't work in 3dsmax too without vray licence.
In general it should be enought to have vantage licence if you decided to work with gpu renderings on your soft.
2nd option is to sell a bundle: "Vantage solo + Vray Solo" in affordable price, that could work together.
