For those unaware of Petruz's work, they make the blendshapes and props for their models as a separate FBX. The result being that you end up having props and clothes with their own separate armatures that makes porting into an avatar a pain.

Because the armatures are the same, I'm trying to put all the clothes/props with the rigged model into a single FBX that can move along with the model. The blendshapes issue was solved by transferring them from the Blend file to the FBX version thank the lord.

Bonus if anyone help explaining how to combine these props so they don't clutter the FBX.
