After rendering with the help of SolidRocks i loose all materials aasignments. (the arrows are gone). It's not a solution for me to use "Import all scene materials" because while importing 3ds max splits instance bitmaps (which were assigned to separate materials, instance in single materials imports with no change) - so instead of 1 map i got several with same name. How to solve this problem? (with SolidRocks or core 3ds max solution)
