Description

Dragging a Cine Camera Actor into the world causes the editor to crash. I reproduced this with both Oculus and Vive, however had a more successful repro rate with Oculus.

Steps to Reproduce

Setup:
Have access to QAGame
Have access to a VR headset and controllers

Repro:

  1. Open QAGame
  2. Enable VR Mode
  3. Navigate to the Modes Panel and click on the Cinematic tab
  4. Drag a Cine Camera Actor into the world (if this doesn't cause the crash then drag in another)
