Note:
Later today we’ll upload to the ARK Dev Kit the following Maya Source Rigs:
FPV Hatchet
FPV Pistol
FPV Bow
Male TPV
Female TPV
This will make it much, much easier for modders to create new animations for the first person weapons and third person characters (as well as make new meshes that are rigged to those skeletons, if they wish).
We’ll probably add the currently-released dino sources and the rest of the FPV weapons later too, but this is a start at least 
Cheers,
