Hmm, not really. This is essentially the same as the second set of joints in my original scene file. The end of the joint chain is able to drift away from the goal. And the elbow doesn't move.

Here's the simple test scene from my screenshots. overextended mechanical joint.c4d

Hello! Longtime user but first time poster. I'm having trouble coming up with a solution to this type of mechanical arm. As you can see the hinge is not aligned with the two ends, making it technically hyperextended. I need the two ends to remain perfectly fixed at their goals without drifting off because their driven by other moving objects that they're connected to. As pictured, a normal IK chain with the joints at the physical pivots wont work because it'll bend backwards. I've tried a few different workarounds similar to the one pictures but with no real success. My rigging skills are intermediate. Has anyone else had to solve this type of geometric puzzle? I've searched everywhere if others have had this issue but this is a very unconventional type of hinge. Thanks!
