Map Button Overrides the environment settings with the specified map. By specifying an environment map, you override the environment map for the scene as a whole. Both reflection and refraction use the scene-wide environment map unless you use this option to specify another map. With this control, you can use different environment maps on a per-object basis, or provide an environment to specified objects when the scene as a whole has none. Raytraced Reflection and Refraction Antialiaser group Controls in this group let you override the global antialiasing settings for raytraced maps and materials. They are unavailable if antialiasing is turned off globally. To turn on antialiasing globally, choose Rendering > Raytracer Settings to open the Raytracer Global Parameters rollout on page 6221. On When on, uses antialiasing. Default=unavailable unless global antialiasing is turned on; on if global antialiasing is turned on. Drop-down list Chooses which antialiasing settings to use. There are three options: ■ Use Global Antialiasing Settings (The default.) Uses the global antialiasing settings. Click ... to open the Raytracer Global Parameters rollout on page 6221. ■ Fast Adaptive Antialiaser Uses the Fast Adaptive antialiaser, regardless of the global setting. Click ... to open the Fast Adaptive Antialiaser dialog on page 5522. ■ Multiresolution Adaptive Antialiaser Uses the Multiresolution Adaptive antialiaser, regardless of the global setting. Click ... to open the Multiresolution Adaptive Antialiaser dialog on page 5524. When you change settings for an antialiaser locally, you don't affect the global settings for that antialiaser.
