Link rigged object to another rigged object? help...

HI Guys,

I got a question about how to link two separate rigged objects.

i.e. Let say have a hydraulic arm. The arm mesh is rigged and got some animation, now I wanna add new rigged fbx (hydraulics) to the arm mesh like we do with static meshes > add component. I dont see this option for rigged meshes. How can I do that?

basically, linking two separate rigged meshes together…so they always follow each other and are positioned well.

My other question is: I also dont see the option to create collision for such a object… how can I create a collision (custom/auto) for rigged objects?

Thank you
