Controlrig editor/compiler issues

Concerns Unreal 5.8.3.

I encounter a number of problems in creating a controlrig from scratch.

In short:

  • Changing local and global transform and rotation of a null or control to zero.
  • Placing the shape of a control based on the global tranform of a null doesn’t always work, but the function is ok
  • Compilation may have impact on unchanged controls, eg turn 90 degrees on the pelvis after changing a control in the foot.
  • Undo actions do not always work. Some cannot he reversed at all
  • After restarting the engine and reopening the controlrig, all is correct, until the first compilation, even without changes.

I want to create a bug report, but describing how to recontruct it is not doable. I am willing to supply the project in which I encounter the issues.
