I'm using the Controllable version of this skeleton in my mod for max compatibility with other mods and because it has a ton of places to mount things on the character.

If you open the 'For Modders' folder's Skeleton .nif from this mod in Nifskope, there's a Bip01 R Hp1 NiNode (Block #1101). I'd like to mount a mesh here for a custom item classified as a clothing piece in my game. My world model is just the static version of my model, if you drop it, it floats. Not exactly sure why.
I've attached my static model nifskope data (static.png) and my clothing(biped model) nifskope data. BSXFlags is 2 on both of them.
In my esp it's marked as a "Tail" under Biped Object in CS. I'm not sure what this should be set to since my Srn is set to a custom node for a modded skeleton. I'd prefer to keep this in nifskope as much as possible, because while the learning curve is steep, it's a walk in the park to add custom content in the game once you get it down. When I equip the item in the game, regardless of what I have equipped, it doesn't show up.
Thanks for your time if you decide to chime in.
