Is it best to uninstall all my texture mods before installing this? And then adding them on again afterwards as needed in order to not conflict with the update? Or does it just act like another mod and will overwrite as needed?
It all depends on the Texture Packs that you are using. I would imagine that some mod sorting or other method would be needed. With ESPs, just adjust the load order so the other ESPs load after this. With loose files, Archive Invalidation or some other method. See the mods section of the boards for the best way to handle this.
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.
Are these textures loose or in BSA files?
If machine can't handle the textures - what is the best way to roll back without reinstalling?
What in my current install needs to be backed up other than the current textures BSA?
Need info before I can move on this. thanks
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
