在做GI渲染的时候，颜色溢出是很常见的问题，本教材以一个简单的室内场景做渲染，讲解在用Vray渲染的时候，如果解决这个问题

Color bleed is a common problem in global illumination (GI) renders, as colors are transferred by means of indirect light reflection. By understanding how light works in the real world, and using 3ds Max and V-Ray to mimic that behavior virtually, you can prevent most color bleed problems. Join Brian Bradley as he demonstrates the causes of—and solutions for—the color bleed that occurs in V-Ray GI renders. Learn how to control color bleed in a physically accurate manner (as you could on a real-world set), and by using GI-specific tools along with other nonphysical controls such as Materials Overrides and the V-Ray Object Properties dialog.
