Problem with limits in IK
Hi! I’am working with Joints and Inverse Kinematics (IK).
When I set the limits of a Joint (in the ‘Kinematics’ section), all works fine, as long as the joint it is not the first joint of the IK chain.
Howeber, when I set the limits of the first Joint (‘Joint.0’) of the IK Chain, they are ignored, since the Joint rotates witch complete liberty (ignoring the limits that I set).
What I have to do in order to limit the rotation of the first Joint of a IK Chain when I use Inverse Kinematics (IK)?
(PD: Sorry for my bad english)

moving the IK tag to the second joint in the chain will freeze the first ‘bone’ but that’s an all or nothing thing.
-
the only other thing I can see so far is to add a Constraint tag to the second joint and use it to Surface constrain to a hemisphere.

Thank you Brian, I’m trying some workarounds with Costraints but so far the best I can achieve is not using joints at all, just Null and costraints (Aim, Up)
