yaohaosquall Posted December 3, 2012 Share Posted December 3, 2012 Hi~ I'm trying to build a raytrace shader,and I want to control reflection by a reflection map.however, I don't know how to transform the reflection map just like using a environment light.I thoght maybe I can transform the shading points and normals before feeding them into the trace operator,but, is there any easier way to do that?

slayerk Posted December 4, 2012 Share Posted December 4, 2012 (edited) read help for environment() function. "envobj" option. also search "optional raytrace parameters" in help. Edited December 4, 2012 by slayerk Quote Link to comment Share on other sites More sharing options...
