Hello
After looking into your issue I was able to get my DK1 to work on the 4.7.6 version of the engine by going into the Rift Display mode and Unchecking the DK1 Legacy App Support. Could you give this a try and let me know if this solves your issue. I hope this helps.
Example/Steps taken:
- Open the configuration utility
- Tools > Rift Display mode > uncheck “DK1 Legacy App Support”
- Open 4.7.6 version of the engine (do this only after all the settings have been changed)
- Load up a project
- Launch as a standalone game
- Press Alt+Enter
Note: Newer versions of the engine Have a VR Preview mode that will launch the project straight into VR mode
VR preview example:
Make it a great day
