Willi Posted September 14, 2012 Share Posted September 14, 2012 hi all, here is a preview of my new shader that i am developing. its a physical sky shader based on "preetham´s" paper. at the moment it is only an ambient shader that can be applied on an "environment sphere" for background renderings. it can be controlled by a light or by date, time, longitudes and lattitudes. i hope it can be also implemented for sampling an ambient occlusion environment, so that we also have one more option in the "global ambience" slot...
