Added a Roughness option to the Metallic Carpaint Clearcoat section for imitating clearcoat spray paint high-gloss satin and matte finishes in OpenGL, CPU raytracing, and GPU raytracing. Now, you can control the roughness, thickness, and density of the clearcoat for most materials, such as Plastic, Brushed Metal, Metallic Carpaint, and Carbon (2D/3D).
