Description

Hand rotation is wrong when the Character rotates with Locomotion

Steps to reproduce

Open the MovementISDKLocomotion scene (from the Movement SDK Advanced Samples) -> click the StylizedCharacterLocomotion prefab in the scene and in the Character Retargeter change the weight of the ISDK Source Processor Container to 1.0 and the Max Displacement to 1.0. Start the scene and rotate with the right joystick.

No logs required.

Additional info

Fix for this issue (at least for me):
Changing line 339 of the ISDKSkeletalProcessor from:
var isdkRotation = isdkPose.rotation;
to
var isdkRotation = Quaternion.Inverse(_cameraRig.transform.rotation) * isdkPose.rotation;
Although moving the Inverse operation outside the loop is better

Hello, this issue should be fixed in our v78 release (https://github.com/oculus-samples/Unity-Movement/releases/tag/v78.0.0). Can you please try that and see if it works for you or not?
