Hello,
My name is Timothy and it's my first post here, so thank you in advance for your help.
I'm rigging a character( a drummer) but I'm gonna focus on the arm and forearm chain. I'd like to limit the angle rotation of the arm while I don't need lo limit the forearm 's rotation.
Is there a parameter I'm not aware of or do I need some extra line of code?
Arm and forearm are in the same layer and I used puppet pins to create bones and IK rigging.
Thank you

How to limit angle rotation in IK character rigging
Re: How to limit angle rotation in IK character rigging
Hi Timothy,
What you're asking is a difficult thing, the only way to achieve that would be to modifiy the IK expressions created by Duik. But actually, what you want is NOT a two-layer IK.
Maybe you could achieve this following these steps:
- create a one-layer IK on the forearm using a controller on the hand
- create another one-layer IK on the arm, using the same controller
- adjust the "weight" property of the IK of the arm to limit its rotation
(see the user guide for more infos on how to create IKs if you need)
I think this would do the trick

Hi Duduf,
I've just tried your method: it's easy to implement and most important thing it works !
Thank you very much!

Good!
That's the way I rig shoulders, but I never tested this to rig the arm/forearm, glad to know it worked for you!
