Using VRay Global Illumination GI (Realistic Lighting)By Aziz | 3D Studio Max | Intermediate
This short tutorial on how to use VRay's Global Illumination feature will show you one method for creating realistic looking lighting for a scene. VRay is a very powerful external render engine for Max made by Chaos Group. VRay has many features including the ability to to physically accurate full global illumination, advanced material shaders and enhancements for speeding up rendering time. You can check the Chaos Group website to learn more about the various VRay features.
This is an intermediate level tutorial and it will not explore any modelling techniques, you will have to create a simple scene with a few objects laying around to follow this tutorial.
