Transform constraint breaks constraints on child bones?
Hey there, long time spine user here, I love the software! I'm having a bit of an issue with a project I'm working on that I havent come across before.
I have a character skeleton that uses constraints for various things, for example IK constraints for legs/feet, offsetting the head of a character skin with a longer neck, etc. I have added a new 'grab' bone with a transform constraint attached to the characters HIP bone, so the character can be 'grabbed' and controlled by this bone that is outside characters heirarchy (all of the characters bones are children to the HIP bone, everything outside that are used for effects etc). This new 'grab' bone constraint breaks all of the constraints on the characters child bones, even when it is not active (all sliders are set to 0). If I delete the 'grab' constraint then the child constraints work fine again.
Is it not possible to have constraints on parents of bones with constraints on, even if they are not active? If its not possible, I wonder if there is a different way to achieve my goal without a transform constraint. I don't want to change the heirachy of the characters hip bone, it needs to be controlled by this other 'grab' bone. I hope this makes sense, any help is much appreciated - thanks!
Hello,
This sounds like a matter of constraints order: Constraints: Order
Try pressing the Reset
button on the constraints node and see if you still encounter this problem. Often this is enough to fix order problems, otherwise you can also manually reorder the constraints to find the perfect sequence.
Oh my goodness, it was that simple! Now my cute character can be pulled into a hell portal by a giant Erdrich tentacle, and its all thanks to you Thanks so much!
