How to remove unused textures and materials I have a lot of materials and textures in my scene that I don't use, but idk how to delete them. Could someone help me and tell me how to do that? 'Cause it eats up a lot of memory and crashes (._. ) Every time I import an object it creates a few copies of the same material\texture, for some reason...
If you go to the outliner and set the mode to "blend file" you can control the contents of the blend file. (And remove textures, materials etc if they are not in use at the moment)

For the issue of multiplication when importing I would really go through the import settings and make sure that you aren't importing materials/textures, and then just recreate the shading in blender after import.
