Question

Arm Bending Error

While I create arm position with Dragger, there is happening a bending error. I've tried Arm Ik on/off and auto bend on/off but still the same error. Can you help me with that? I added a video attachment.

Sorry for the late reply. I am a developer of Arm IK (now called Limb IK).

In your screen capture, I see that Elbow Strength is set to 0. This makes Arm IK do nothing for the elbow bends. Can you try setting it to 100% and see if you get predictable bend directions?

Sometimes you just have to play around with moving the sticks further way from the handles. Usually when the elbow 'pops' you can fix it by shifting the elbow handle closer to the body (or further away from the body).

 

Sometimes you have to modify your original artwork and rigging. Did you create the puppet in the 'A' position? Sometimes if your puppet isn't created in the 'A' position, it can cause arm issues. Particularly when blending between poses.

Hope one of those things helps you out!

Hi, I'm having issues with the arm bending, I was working well with my puppet, but I needed the arms to work both ways, so, I modified the rig moving the elbows more in the middle of the arm and when I wen't back to the record mode everything goes bananas!. I had recorded several takes, but everytime I play the animation the bending goes wrong or the other way. not even putting keyframes to the reverse arm bend boxes fix the issue, I need Help! (:_()

Try moving the elbow handle a few pixels closer to the body. The elbow position can influence the bend direction.
