Crash playing a HapticFeedbackEffect_Soundwave with no sound assigned

Crash playing a HapticFeedbackEffect_Soundwave with no sound assigned

Description

Crash attempting to use a HapticFeedbackEffect_SoundWave with no sound set on it (i.e. a newly created one.)

Found on:
4.13.1 Binary CL-3120228
//UE4/Release-4.13 CL-3123398

Similar to [Link Removed] (Crash when playing a HapticFeedbackEffect_Soundwave), but only occurs with no sound assigned to the effect.

Steps to Reproduce
  1. Have an Oculus set up and a right touch controller.
  2. Open UE4Editor.exe QAGAME TM-MotionControllers
  3. Create a NewHapticFeedbackEffect_SoundWave asset
    1. Save it
    2. Close it
  4. Open the QA_MoCoComponents asset in to the blueprint editor
  5. Scroll down in the event graph to the 'Right Haptics' comment box, and change the Play Haptic Effect node (that is connected to (R) Trigger event) to using your aforecreated NewHapticFeedbackEffect_SoundWave
  6. Play in VR Preview
  7. Press E on the keyboard (this just enabled the haptics related nodes)
  8. Pull the right trigger on the oculus touch controller.

Result: Crash
