Chain length

Anonymous 4 years ago • updated by 4 years ago • 1

Hello,

By using UMotion Pro i am trying to animate a xenomorph with a tail made out of 20 bones but when i try to create the tail IK i can only add 10 bones max to the chain length. Is this the upper limit for the chain length and how do i extend it to fit my character?

You mention in one of your video tutorials that you will do a tutorial about Custom IK (generic character). Is that out yet and if so can you please provide the link?

thanks

UMotion Version:

1.22.0

Unity Version:

2020.1.1f1

Hi,
thank you very much for your support request.

Your request is very similar to another one I received in the past so I'm linking my answer here: https://support.soxware.com/communities/1/topics/529-tail-bones-weight#comment-691

As mentioned in my answer linked above, the IK solver's primary use-case is for 2 bone IK situations. More than 10 bones is unfortunately not a use case the solver has been designed for and is thus not supported. Please note that you can of course extend UMotion with any 3rd party (or custom written) IK solvers specifically made for tails using UMotion's callback system. More information can be found in the manual at "Pose Editor / Options / Extending UMotion".

If you have any further questions, don't hesitate to comment in this thread.

Best regards,

Peter
