Hi, I got HTC Vive today at work and I have some serious issues with it. When in stereo mode on one of ongoing VR projects it seems like both eyes are pointing in different directions which leads to very distorted view (no issues with Oculus rift DK2). I have the same issue with the UE4.11 version of the project. Why is this happening? Am I missing something with the setup? When I test it on blank project, it works normally. ---

Hello, Based on your description, this issue seems to be related to UE-30974, which is an issue with certain maps not being able to render properly in stereo mode. This issue is currently being investigated by our developers, but there is no timeline for when a fix will be released. Thank you for your report. Have a great day ---

I actually found the problem. I began testing with deleting one by one everything on my scene (which is a lot) and deleted the PP volume and tadaa the stereo mode works. After that I found out the main culprit of the problem which is the setting “screen percentage” it was set to 180, when I revert it to 100 the stereo mode works. If you go over 100 the stereo mode gets broken. ---

Awesome, thanks for providing that information! I will update the report to include the workaround. ---

Hi Guys! Has this been resolved? I’m getting the same issue with the Vive, Screenpercentage in the post process volume wigs it out. I’ve tried ‘HMD sp [200]’ and ‘r.screenpercentage=200’ and neither work in game, the HMD ‘Get screen percentage’ function still returns 0.0 with no visible change. I also tried adding: [SystemSettings] r.screenpercentage=200 To the Config\ DefaultEngine.INI with no luck. What am I missing? Thanks in advance! ---

Hey RStudios, This issue is still under investigation by our developers; however, there is currently no timeline for when a fix will be released. However, the issue you are reporting with screen percentage not working is strange, as I’ve never experienced that before. Would you mind creating a new post in the bug reports section regarding this? Please provide as much information as possible, along with repro steps on how we can reproduce the issue in a clean project. Thank you ---

I am facing this problem with my project at the moment. When I change screen percentage over 100 the view in headset gets broken, only fix is to go to 100. Is there some new info on this issue why is it happenning? ---

Hey, I had the same problem and I fixed it by exporting a build in Shipping not in Development. Hope it helps. Good Day ! ---

Bug is still present in 4.14.3. Screen percentage of 120 broke it, reverting to 100 fixed it. ---

There is a workaround for this bug. Use the “Execute Console Command” node inside the level blueprint and paste this code: r.screenpercentage 100 (just change the 100 value to the one you want).
