Maybe this helps:

If the images are just white check the file path used if it's correct, starting with the addon name/subfolder/filename.dds
If the files do not show at all the format is wrong (yes they use mip maps afaik) or the texture cache is old.
Reformat the textrues like described above at the link -> forum link
https://www.esoui.com/forums/showthr...highlight=.dds
And / Or try to logout and reset the texture cache file live/shader_cache.cooked and after login the textures get new created/cached.
Please keep in mind that creating any offending or unethic textures and releasing it to the public is nothing we should do.
I'm not saying you will do that, it's just a reminder in general.
