_d = Diffuse map _s = Specular map _g = Gloss map _n = Normal Map _nY+ = Normal Map with y+ _t = Transparency Map _h = Height Map _e = Emissive Map _p = Only on Decal images, this is the preview image of what the decal looks like on a transparent background. _r = Reflection Mask, to be used if your scene has a cube-map, or other reflective objects or properties.
Remember... When something is ‘new and improved!’ which is it? If it’s new, then there has never been anything before it. If it’s an improvement, then there must have been something before it.
