Ik/Fk Match with No Flip

Hi Guys,

I am setting up a standard 3 chain FK/IK setup for the arms. I also implementing the No Flip Solution for the IK.

I am writing a script to match from FK to IK. Now I am able to match the IK to FK and also figure out the position of IK control when swtiching from FK to IK.

However I am unable to figure out the correct twist value so that the IK shoulder/elbow lines up with the FK counterpart.

I am not very good at maths, so kind of stuck here.

Cheers

you should check out Jason Schleifer's Animator Friendly Rigging. He has a script that does this. You might could dissect his script to figure it out. I think it goes back and forth many times to eventually end up with the closest match. not sure though.

I would help but im totally swamped and haven't really dove down that rabbit hole yet.

Thanks Adam. I don't have his book but I eventually figured it out myself. I'll post the script if someone else wants it.

Hey pritishd,

I'd love to see the script if you wouldn't mind posting or emailing.

Thanks,
