Normal Node - Cycles reviewed by Brecht, with help from Lukas. Note: dot is reversed compared to Blender. In Blender Normals point outside, while in Cycles they point inside. If you use your own custom vector with the Normal Node you will see a difference. If you feed it with object normals it should work just as good. 2011-12-16 18:15:07 +00:00
Cleanup: Fix build warnings from OSL shader compilation There were to copies of stdosl.h one from stock OSL and one in the cycles tree augmented with cycles specific closures. moved the cycles ones to stdcycles.h and copied the stock stdosl.h and accompanying headers from the OSL shader folder. for further details see D6812.
