Like the title said, null textures to weapon mod meshes keep reverting after I close the GECK and reopening it. Trying to give weapon mods to the Marine assault rifle from TSC Vegas using meshes from Mothership Crew Weapons Addon. There was a mesh with just a silencer and a mesh with a scope, silencer, and foregrip. Tried to apply null textures to the latter mesh to give it a plain scoped version, using the full mesh, minus the foregrip, as the full modded mesh. Pictures to show what I mean: http://imgur.com/a/kXxAx Any idea what's going on? I mean, I'm fixing things by deleting them in NifSkope but just curious why it's happening.
