I was riggin a simple blender character, when I noticed my track to constraint stopped
working after I just checked if it worked. I apply the track to constraint by selecting the
bone I want to point to the knee.r bone. After I applied it I can see it works when I select
which axis to use. But If I choose an other axis than the default (y axis) then the knee.r wont work no more as if its not constrained !?
This is really frustrating as I have ablsolutly no idea why It would do this ?
Hi!
I’m not sur that I’ve understood well, and I’ve not time right now to make a trial, but I think that you could solve your problem using an empty for the Track To constraint , and copy its rotation by applying a Copy rotation constraint to the bone.
The only thing that I don’t see well is the parent that you would use for the empty…
You could probably parent the empty to the previous bone in the chain, and put it at the center of rotation of the bone you need to constraint…
Is it understandable ? Am I completely wrong ? :rolleyes:
Philippe.
Thanks for your suggestion, but I must admit I used a IK in stead, and worked right away.
I read somewhere in the wiki documents that the track to constraint could be alittle tricky.
Something to do with the fact you wanna use the Z axis of the upper_leg which is against
the way orientation of the upper_leg bone is set by default, if i got it right !?
But anyways if an IK sovler can do it then I wont have any problems with that. but thank again for helping.
