I finally found out how to extract the Nif files, and I extracted armor and weapons, thinking that they were the only ones I needed for my mod, but I noticed that robes weren't in there; rather, they were in the clothes section of the meshes. The first time I extracted it worked fine, but for some reason it doesn't work anymore. I followed the exact same procedures, but B.A.E just isn't accepting the files (there's a red cross in circle next to my cursor whenever I try to drag it in.) I tried dragging in Meshes, Meshes > meshes, and even Meshes > meshes > clothing, but it still didn't work. Any help is highly appreciated. edit: I found the error. I already had them extracted and didn't know it. I'm so sorry for the wasted time and confusion if you tried looking this up or anything like that. It's just that for some reason I couldn't see the specific NIF files at first.
