Trying to create a simple bone rig with two siblings and this wonderful piece of software crashes every time I try to add a second sibling. Disappointing. I used to love Flash.
I'm trying to recreate an existing armature but the software keeps dying whenenver I try to add the outline for the forearm as a sibling to the filled forearm. Since the software seems to incapable of processing that action. Can I simply define a new 'root' bone somehow.
