(WIP, don't bugs for this in tracker yet please!) - New Panel "Layers" in Material buttons, allows to add unlimited amount of materials on top of each other. - Every Layer is actually just another Material, which gets rendered/shaded (including texture), and then added on top of previous layer with an operation like Mix, Add, Mult, etc. - Layers render fully independent, so bumpmaps are not passed on to next layers. - Per Layer you can set if it influences Diffuse, Specular or Alpha - If a Material returns alpha (like from texture), the alpha value is used for adding the layers too. - New texture "Map To" channel allows to have a texture work on a Layer - Each layer, including basis Material, can be turned on/off individually Notes: - at this moment, the full shading pass happens for each layer, including shadow, AO and raytraced mirror or transparency... - I had to remove old hacks from preview render, which corrected reflected normals for preview texturing. - still needs loadsa testing!
