I think I didn't understand half of it, sorry. I looked at CourserF , I've seen all that you mentioned, but have no idea how is this supposed to fix my problem. How do I know which slot applies for each texture? Regarding Materials, if I select another material, for example the BGSM of the Jacket, then the Leggings are changing the texture, it is applying the Jaket texture. I would assume that I need to create a material file for the Leggings ? Save it somewhere then somehow assign the Leggings mesh from Nifskope to that Leggings BGSM.
