[Tutorials] Lynda Mental Ray Control Color Bleed in 3ds Max

Color bleed is a common problem in illumination renders, where colors are transferred by reflections from indirect light. By understanding how light works in the real world, and using 3ds Max and mental ray to mimic that behavior virtually, you can prevent most color bleed problems. Join Brian Bradley as he explores GI-specific tools such as Final Gather (FG) and photon-based controls, and nonphysical controls such as the rayswitch map and object properties. These tips are invaluable for lighting and rendering specialists who control or eliminate excessive color bleed in the most fast and efficient manner possible.
Topics include:
Controlling reflectance
Understanding how geometry setup affects color bleed
Choosing color placement carefully
Using the FG Diffuse Bounce control and Photon Energy setting
Controlling color bleed via object property controls
Using the rayswitch map
