I have a tight deadline I'm working towards where I need to create a bunch of extra animations for a Bear model.

I've created a new project in umotion pro and loaded up the model, the bone structure looks great but the problem is the bones don't seem to be 'linked'. I.e. if I move one bone it disconnects from the bones next to it.

I'm pretty sure this is something I've missed but as I'm fairly new to animation, I'd be extremely grateful if you could point me to the appropriate section of the manual or video tutorial to help me fix the rig.

Thank you,

Hi Tommy,
thank you very much for your support request.

UMotion displays the rig and it's parent-child linkage the same way it has been defined in the 3D modeling application where the model has been created. If you want to change something in the parent child relationship, you would usually do this in the 3D modeling application.

Usually the modeler always setup bones in such a way, that the child bone moves with the parent bone. So are you sure you used the correct bones (and not some "helper" bones that the animator created)?

You can use the Child-Of constraint to change the parent-child relationship in an animation (but I would rather try to setup the rig correctly in a modeling application). The child-of constraint doesn't really change the hierarchy, it just moves the affecting bones in such a way, as if it had a different parent ("faking" the effect of a changed hierarchy): (Pro 3) Child-Of Constraint - UMotion Official Tutorials

Please let me know if you have any follow-up questions.

Best regards,
