Elias Posted September 19, 2013 Share Posted September 19, 2013 Hi gang, I'm trying to assign different diffuse colors on geometry level instead of having a shader per object. But when I change from using baseColor on the mantrasurface to using point color (and no base color) I get very weak speculars. I've looked around in the shader but I can't make sense of this, what am I missing? base_vs_point_color.hipnc Quote Link to comment Share on other sites More sharing options...

Guest tar Posted September 19, 2013 Share Posted September 19, 2013 its not liking my setup for some reason - with 12.5.469 -OsX 10.8.5 Quote Link to comment Share on other sites More sharing options...
Green-Man Posted September 20, 2013 Share Posted September 20, 2013 The reason is the reflMaskColor1 operator inside the Mantra Surface. It has Use Point Color parameter turned on by default. So it tints the reflections by the Cd attribute if this attribute exist. If you turn it off you will have the same reflections in your scene for the first and second frames.
