I'm animating a character using Puppet tool and Duik IK rig, everything works quite lovely so far (knock on wood), except that knees and elbows of the character lack sharp corners that humans have.
In fact, because of no knees and elbows, characters' limbs look kind of like sausages.. :-/
I've experimented with starching and adding extra pins but so far haven't found anything that would solve the issue.
Has anyone dealt with this before?
Is there a work-around for adding sharp edges?
I'm afraid this is more inline with the design of your puppet.
You're using bones, yes?
One way around it would be to draw each shape separately (upper arm, forearm, hand) and link them with a controller on the hand. But it's still tricky because you have to draw it such that it has the shape you want when bent, but not when straight. It's been a while since I've created a puppet in that style, but maybe you could subtly animate the shape path along with the controller so that the arm would shape as you like when it moves.
