It would be usefull to have multiple Texture Stages for a better workflow with shader on level blocks. This texture stages could used in Shaders with entSkin1 ... entSkin4. On this way you don't need multiple materials as example for a detailmap shader or a parallax shader. Or is it possible right now with some tricks like importing FBX levels or convert mdl to level geometry?
This is planned. It won't work through assigning several textures, but through texture names that add two additional textures to a surface texture, f.i. for normal maps or displacement maps.
Ok, thats great for most shaders. But then it doesn't support different scalation on the texture stages or is this only possible with shader code? Different scalation is needed as example for shaders like detail maps.
