Question

Can't get limb IK to work

My puppet's arms do not seem to be responding correctly to the limb ik behavior - they are not bending as expected. When I move the arms up, the forearm show switches to pointing up. It kind of works when I drag the arm toward the body. Also, the limb ik seems to affect each arm separately. This could be because my arms are not exactly identical. Side note: is it possible or useful to put the ik limb behavior separately on each arm if they need different settings?

 

I've tried:

-Dave's tutorial

-Modeling my tags, etc. after Dave's examples

-re-rigging my puppet.. 

nothing!

I'm attaching my puppet (dropbox link) in case anyone is willing to take a look at it.

 

Link to DB puppet 

Thanks!

I downloaded your puppet and dialed in some IK settings for each arm. Just the bend strength and elbow flip threshold.

 

First, make sure you assign the Limb  IK behavior to each arm individually. (ARm L and ARm-R)

Then try these settings in their behavior properties:

 

I hope this helps!

Thanks for checking it out. I tried what you suggested, but not getting the result I'd like.

 

Here's a video clip of Dave's IK Guy puppet.

I see what you're going for. Try these settings (you'll probably want to make swapsets for your hands, or these bends can look unnatural):

Play around with the bend strength and elbow flip threshold until you get it just right. Your rigging is correct.
