When duplicating the same mia_material shader network over and over again and applying the different shaders to several objects, some materials start to behave weirdly in the render specially when using Final Gather (Splotches and other weird artifacts on the surface they are applied on). Is that a bug in MentalRay for Maya? Is duplicating the shader networks a bad habit in MentalRay for Maya, should re-create a material from scratch each time?
