Suggestion: UNBENDALBE JOINTS --- I would like to see a way to give specific joints an "UNBENDABLE" attribute, so that it would effectively allow the user to fuze two or more bones into one "bony structure" with a specific shape and more than one place that muscles can be attached. As an example of how some people might use this, I've seen several YouTube videos in which a person tries to give their creature a "head" which immediately collapses and flops around. LOL! This way they could make a head that at least doesn't collapse. Flopping around is a separate issue. :)
