Hello!
I would like to ask if someone can help me out with some rigging basics. Especially how to put bones onto already created nulls (I exported .cmd script from PFTrack) to houdini and wonder how to attach Bones to those NULLS.
I've been trying to do so for hours and cannot solve it.
Tried to make shelf tool bones and rename my nulls, tweaking CHOPs network but nothing.

If someone can explain, post link to video, or repair my .hiplc file, it would be awesome!

Thanks for any reply!

(I have stripped it so there is only one finger animation - 4 nulls)
