How can I get rid of invisible textures? I mean if I made a solid cub touching the wall of substructed ones I get some invisible faces at this solid cub. These faces have some textures. How can I replace this texes with another one? I use richrig.utx pack for example, but I use only 4 texes from this. And I want put these 4 texes to MyLevel package, so ppls needn't DL Richrig.utx. But I cant replace those invisible textures (they are still from Richrig.utx) and if ppls doesn't have this pack my map won't launch on their machines. Sorry for my english, methink it's really suñk!!!
