I posted this in another topic where you asked for guidance, but I'll copy/paste it here just in case you miss it: This is most likely an issue related to the compression you're using while saving your files. If you're simply attempting to save a regular texture file (ie. not a specular/normal map), choose these options when the popup menu appears: Texture Type: Color Compression: BC1 4bpp (sRGB, DX10+) Mip Maps: Auto Generate Note that the compression should be the 2nd option down the list. If you need any more modding advices I'd suggest you join this Discord server because I rarely check these forums on the Nexus: https://discord.gg/qe73qtG
