Hi Robin,

thank you very much for your support request.

Have you watched the IK video tutorial (at 2:36 of the video tutorial, the manual IK setup is shown which is necessary in your case)?

Here is the related page in the manual: https://www.soxware.com/umotion-manual/InverseKinematics.html

I recommend trying to setup IK for one leg, and if that works repeat the process for the other legs.


Please let me know in case you need further assistance.

Best regards,

Peter

thanks for your fantastic software Peter yes I found that yesterday was going to write this morning it’s got me in the right direction the only thing I need to figure out is how to pin the feet cheers Robin

Here are the related video tutorials on how to setup IK pinning. IK pinning is a special use-case of the child-of constraint, so please watch the general child-of constraint video tutorial beforehand:
