3.46.1-pre.1

Needle Engine

• Fix: WebXR teleport and rotation now takes user position in rig space into account. This means when teleporting the user is now placed at the expected ray target point and when rotating the user is rotated around himself as expected (and the position stays the same)
• Fix: Animation component fadeDuration didn't fade out previously playing animations but instead stop immediately

Unity Integration

• Fix: Update dialogue
