Playing with the KineFX setup.

Using an FBX character import node.

I'd like to pin a joint to an animated external point/geo while running a ragdoll simulation.
Essentially a character with a guide wire the lifts it up/down while passed out.

I see the "external constraints" in the ragdoll constraints node, but it doesn't seem to do anything when I pass external (packed) geometry into it.

Any ideas?

Thanks!
