If you don't tick 33 your pipboy is invisible. So you wouldn't be able to see your map, inventory, etc. That's an interesting find... are your hands still visible, or the whole arm disappears? http://i.imgur.com/xediHeE.jpg That's Maxson's Battlecoat equipped with these slots ticked http://i.imgur.com/iMtE2Qx.jpg It also makes the armor completely invisible. So you're completely naked. I'm currently working on another custom mesh and for whatever reason it's invisible (albeit the pipboy actually shows up lol) unless I tick 41, 42, and 43
