For context I'm looking to make an armor replacer I want to make something that's more revealing but tasteful the best I can find is the spicegear collections but I wanna make something a bit more high fantasy, and not just armor and robes that are bikinis.

That being said I've been able to learn a little in bodyslide but I would feel a lot better about learning and using blender as I could use those skills elsewhere. However I'm having the most trouble importing the nif files that I'm working on into blender, and if I try to convert the nif file to an obj with nifscope and try to import it to blender and edit it that way, no body or armor or anything loads into blender so I'm just looking for a good tutorial/video to figure this stuff out.
