data can't be sent to ue

[ahellpoet]

I create a joint in Maya2022 and use a controller(nurbsCurve) to constrain it. when I operate on the controller, the joint data can't be sent to the engine(e.g UE4) but it works fine when I operate on the joint directly.
This problem does not exist in Maya 2018.Data can be sent by operating on either the joint or the controller.
how can I solve this problem?

I am having the very same problem :(

same, seems like using controller to change joint's transform cannot call attributeChangedCallback on joint node in Maya2022. bug?

Thank you for brining this our attention. We have been able to reproduce the issue. We are investigating it. We cannot provide an ETA for now.

It seems to be solved by specifying a Root that includes rig and bone as shown below.

root(← Synchronize here)
  └ rig
  └ bone

In games, rig and bone often have separate Roots, so it would be nice to be able to sync them in a separate state.
