Crash after weird combination of stereo on/off calls and activating Oculus

Build version: 4.14.3

Description: Crash when using stereo on/off commands in development build. The game crashes after a weird combination of stereo on/off commands and activating the Oculus by putting it on your head (as described below). I found this issue in my project and could reproduce it in a clean project.

Repro Steps:

  2. Open the editor and create FPC C++ project
  3. Open FPC Blueprint
  4. Add the nodes as shown in the attached image
  5. Set build configuration settings to Development
  6. Save all
  7. Package for Windows 64 bit
  8. Start .exe
  9. Press ‘O’ key
  10. Activate Oculus by putting it on your head (or by using your hand)
  11. Deactivate it by putting it down again
  12. Press ‘P’ key
  13. Press ‘O’ key again
  14. Game crashes


Hello ndelchen,

First off I would like to thank you for the detailed report. I was able to reproduce this issue in the 4.14 version of the engine. However, after running a few more tests I found that this issue has been resolved in the latest version of the engine. The crash no longer occurs in the 4.15.1 version of the engine. Thank you for your time and information.

Make it a great day

Hello ,
thank you for your answer! I will try with 4.15.1 then!
