I was wandering how to make reflections, for example on the floor... I googled out that you need a "V ray" for doing that. So I downloaded a demo version of that V ray thing, but I have no idea what that actually is. Is that any kind of render? Can anybody tell me something about it? How to install it? (I have installed it, but my Rhino haven´t changed after that, so I doubt I did it wrong) How do I know whether I already have V ray?

Thank you very very much, and I apologize for being just a beginner and asking questions like that
