forearm / calf 'snapping' on IK setups

Recommended Posts

I have been using a modification of the skeleton 2001 for several years. The only problem I see often is the 'snapping' that happens when an IK target (say, a Hand Target null) gets a little out of reach of the limb, and back.

 

This little movie was intended to show a hand rig, but there's this little snapping with the forearm.

I took a look on A:M sample models, and I notice this snapping is present too. Maybe some user with experience in rigging got rid of this? I could use some help.

Try adjusting the euler limit on the forearm in the ik setup (the minimum value in the y axis). If the model has been rigged with a slight bend in the arm, the arm may not be able to fully extend the arm when the hand target has been pulled away.

Thank you very much!

 

I added an euler constraint to my forearm and it worked.. but I found it a little unreliable (the left arm worked fine but the right arm gets scrambled. And the legs didnt work (they still 'snap').

 

Then I tried a Spherical limits constraint, just raising the minimum latitude from 0 to 1, and it now works smoothly, no snapping! Thanks for your help!
