Err, that's weird. I have RX series card and experienced the same purple tint. After I turned off Env Mapping, everything looked as it should.
Edit: I was curious about this, since I'm an AMD user myself. Sorry that didn't work for you. Best of luck in figuring out the root of this problem.
Edit2: I tried one more thing, which leads me to believe it is actually a missing texture. I copied Env Map texture from the mod COCO Lace Body, called pvc_e.dds, and pasted it in the folder of magnolia's burlesque outfit. I opened the BGEM file, in Effects where the main texture for the stocking is, I put pvc_e.dds as Envmap Mask Texture. Environment Mapping in General settings I left on. The stockings looked normal in the game.
No, it's not a missing texture, as only those with AMD cards have the issue. The only reason that might work is that you are swapping that pvc_e.dds for the Magnolia one. That doesn't mean the Magnolia texture is missing. You can also see the effect on this mod https://www.nexusmod...tab=description it all works great, except for the laser sights are purple. Again, the texture is not missing in any way shape or form, just something about the way it is rendered doesn't work on an AMD.
