V-ray Rendering System

ChaosGroup has invented an excellent renderer(a software which renders 3d objects)called V-ray.This plug-in has all the features including global illumination and also caustic effects.It is a good competitor against Brazil Rendering System(developed by SplutterFish) and Mental ray renderer(developed by Mental images).But the best thing about this renderer is that,it is much more cheaper than the two mentioned above.
