I really like blender 4 & 5 sculpting and would like to use to make new body replacer, or just to modify existing bodies. I have no idea how to use niftools. Import is fine but export never work. It constantly throws error if I even change export option. The nodes are broken too on nifskope.

What working intermediary method so I could edit using the new blender and use dusty blender for export? Export as obj first to import on old blender? obj make the mesh blocky.

Or even better if I someone would like tell me how to do with niftools. Please don't ask me to use 2.49b instead.
