Roughness

This channel controls the micro-surface information of the material, ranging from smooth to rough (maximum roughness being 1.0). In general, most materials are going to occupy the (.3-0.9) range of the roughness spectrum, with only exceptionally polished/smooth materials occupying a lower range. When using our provided Material Map Channel Packer tool, this channel also stores Specular AA information to make the effect free at runtime.
