Rotating constraints in PhAT rotates both reference frames. This behavior was previously enabled by holding ALT while rotating, as indicated by an on screen message in PhAT, but has now become the default and the message has been removed. The old behavior can be achieved by holding ALT to rotate only one reference frame, but this is not indicated anywhere.
Expected: The arm is constrained in the opposite direction as originally.
Result: The arm is constrained the same as originally
This is a regression from 4.20 and can be worked around by holding ALT while rotating.
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-70345 in the post.
