I have downloaded Nifskope for maya but I have no idea where to extract it and how to use it. can anyone help me? I really wanna start experimenting on mods. and another question: I created a follower using creation kit and made her mage type. I gave her a staff as a weapon and nothing else in her inventory... but ingame she always has a bow and arrow on her back. how do I remove it? thanks to anyone who can help

I'm not sure if there is one already but I hope someone makes a tutorial for making armor mods that would fit CBBE body types. thanks.
