EDIT It may not be as complicated as dealing with an Archive Invalidation. I would test it then check with the mod authors if the other textures you want are not showing up and they can tell you what to do.
It is ESPs that pull from BSA's that are included in the mod.
Just uncheck the ESPs and the textures will not be used.
Nothing needs to be done to your current install, other than any mods that you may already have that handle Textures, see my above comment on that
So a ESP that references a BSA DOES override the loose files in the custom made "textures" folders created/used by mods like Vurts/Skyrim 2K HD and others? Im so confused...i thought loose files ALWAYS had predence over BSA's xD!! My head hurts lol
