Getting custom animations to work in third person

[TheRizzler1]

I've completed the first person custom animations for my weapon and am in the middle of trying to get some vanilla animations to work (the double barrelled shotgun) purely for testing and making sure the weapon loads these animations, but no animations seem to load at all

 

 

Here's what my additive subgraph looks like so far. (one / two) The first person one works fine.

 

It seems this has something to do with third person animations;

Generating metadata - I'm not exactly sure what needs to be done here (I can't make sense of the instructions). I'm almost completely done, it's just the third person animations, so I'd greatly appreciate someone explaining how to do this to me!
