There is documentation out there if you look through the net. Between all the videos on the Chaos YouTube page, the manuals that exist for the plug-in, and other V-Ray for Max sites, you can get a good handle on this plug-in. I have to admit it took me a good year before I was comfortable with it. So plan on putting some serious time into it. But once you know V-Ray, you can use that if you move on to MAX or Blender, so it pays off. I would recommend it highly.
