Actualy it makes assumptions about the lighting scheme used, and it "boosts" the visible reflection of the sun using a texture instead ofthe light's specular in the specular pass. That gets to be less aparent in the Rembrandt specular pass.(That would be easily converted by using the sun position, but we don't have that in the geometry pass :( ) One other issue that needs to be investigated is the changing specular position related to camera direction in Rembrandt (the leads to the ugly black banding in other objects too). It's visible on any object at certain surface to camera angle. -Regards, Emilian ------------------------------------------------------------------------------ For Developers, A Lot Can Happen In A Second.
