UE 4.12p4 Editor crashes when the OSVR plugin is enabled #72

Closed demonixis closed 8 years ago

HI,

Unreal Engine 4.12 preview 4 has the OSVR plugin so we can try to enable it. However when I enable it, even if I disable all other VR plugins, the editor crashes on load. The project can't be loaded because the editor crashes at the startup.

The crash log

I hope it can help you to fix it.

How to reproduce this bug

  1. Start the editor with the FPS project (tested with Blueprint)
  2. Go to menu / edit / plugins
  3. Check the OSVR plugin
  4. (optional) You can uncheck all other VR plugins
  5. Click on restart the editor
  6. The editor crashes

Tested with latest release builds and code on master branch. Seems to work OK. Feel free to re-open if you're still having crashes though.
