Elbow type animation with Joints

[Adam Trachtenberg]

You’ve got two IK chains in your setup: one running from the root null to joint2 and another running from joint1 to joint3. So you have one stationary point that’s the root of the first chain, and then you have another stationary point that’s locked in place because it’s stuck to the goal of the second chain. I would not have thought to set it up that way, but it obviously works!

Do you know another way to set it up? I wish there were a way where to move it, I could just rotate the part connected to the arm, and it would then bend the arm depending on its rotation.

Howdy,

Here is a simpler setup.

Seems so obvious when you see it done right. 😉

Howdy,

Hehe, well when you do rigging all the time, you begin to notice the little obvious things. ;o)
