I am fairly new to the engine and to VR, looking into the answer hub I found another question that presented my same problem, the “(unresponsive) UE4Editor.exe” while the SteamVR says that Vive is Ready.
The solution presented in the post was to activate a stereo on command either on the console or on the level blueprint. However in my case I cannot get this solution to work. Even though I added the command in one of my blueprints at the next launch the SteamVR still gave the same error.
I rebooted the system and activated SteamVR, and it did not present any errors, after confirming that, I launched unreal editor and the error came up again. In this case I did not launch a project or anything just the starting menu before choosing which project to open. I opened a project anyway and the PlayVR button was grey. Yesterday when this problem first appeared, I mean the “(unresponsive) UE4Editor.exe”, the PlayVR button was clickable and it made me see and interact with the default Vive environment (or Unreal environment I am not sure) instead of my project, while now I cannot run it.
Other than hoping for a solution from you wonderful community, I wonder if the solution presented in the other post with the stereo on command is where I did it wrong and I inserted incorrectly into my blue print.
Thank you so much!
