Either way how do I do that? How do I change the paths in the nif? Or how do I make a new txst to use new textures?
txset: find miscellaneous / texture sets in object palette, create new, enter new textures in list (1st slot actual texture, 3rd slot normal map), name & save set; click 'model' in your base models tab, enter your txset to the empty slots, rename object, save.
paths in nif: get nifskope, find BSShaderTextureSet / Textures in the tree view, change textures, save new nif; in ck, open any model of your desired type, click 'model', enter your model here, rename & save.
