Anyways i have tried multiple ways of getting custom textures to work. None of them work. Does anyone have all of them working?
Now, i have one strange oddity. A minority of my textures are working. Roads, rocks, terrain and containers. I don't know why architecture, dungeons, People etc don't work. I had them all working years ago.
Just use Nexus Mod Manager for the whole archive invalidation thing. I did, and it works. Just download NMM (you don't actually have to use it to install mods), and check the archive invalidation option. If it's already checked, deactivate it, close NMM, open NMM again and reactivate it
