This is a graphical issue. If you copied all the things you should've copied, it should be okay. Though you should check the load order in module.ini, since it requires a particular order to correctly display separated resource BRF's. If the texture and material BRF's are constructed separately, they should be loaded with higher priority, thus should be textures>materials and everything else in module.ini. If this solution fails, try to change "load resources on demand" option in the launcher.
