View Full Version : IK gone bad on me

04 April 2006, 08:10 AM
I have a foot setup that goes: IK leg, heel bone with IK, toe bone with IK. Each IK handle is parented to a controller and it worked perfectly. Worked that is. Now when I pull the main foot controller the heel joint stays behind and stretches the IK. I have attached a picture for a more clearer example (sorry its such bad quality). Can anyone let me know why this has happened, and a possible way to rectify it. I have tried redoing the IK setup but still get the same result. Really need to figure this one out.

This is a problem that I think is too hard to solve visually. Can you post the .ma?

Just some guesses, either the bone is point constrained to something, or you have the inherits transform attribute turned off for that joint (unlikely), or you're getting a weird reaction because you may have put rotation limits on your joints. From your photo it seems your joint is sticking to worldspace for some reason.

Other possible guesses would be you didn't turn on snap enable and stickiness for your foot IK.

How'd you set up your joints and IK?

selection mask / select component type / miscellaneous in this section you can adjust rotate setup how do you want. select skeloton first then make xyz pivots setup. all the rotate pivots of skletonts must be look same way...

Sorry, unfortunately I can't post the .ma file as its for a project I'm surrently working on and I know the company won't give permission. At the moment I'm just going to go back to a previous version of the file and get back to where I was. Kind sucks that I don't have time to investigate this problem fully but, well, time constraints and all.

Thanks for the suggestions but none fiel seems as it should be, just not working like it should.
