Windows Mixed Reality device screen distortion (SteamVR devices unusable besides )

Build Type: Binary & Source

Build version: 4.18.x affected

Unreal Engine 4.18.x does not line up the screen images properly in the headset when using SteamVR on devices besides the HTC .

This fixes Unreal Engine 4.18 not displaying correctly using SteamVR on Windows Mixed Reality devices. It works with r.ScreenPercentage values. This should also fix the problem Oculus users are having when using SteamVR, but I have not been able to personally test it.

Repro Steps

  1. Run Unreal Engine with SteamVR using any device besides the HTC (WMR devices, Oculus).

Hello J_Paul,

Thank you for the information provided. There is a pull request (UE-53580) that has been submitted to the developers for further consideration. I have provided a link to that pull request below if you are using a source version of the engine you could merge the fix into your current build if needed. I hope that this information helps.

Hi,

The link seems to be broken. Could you provide an updated link.

Hello nageking,

The link is working, however you will get a 404 if you are not logged into github. Please login and try again. This should take you to the page you are looking for. I hope that this information helps.

Hi Rudy,

I believe I need my username in GITHUB which is: nagleking (the ‘l’ is intentional) needs to be added on GITHUB for me to gain access.

Thanks for your help

Do you guys know if this will make it into a 4.18 patch after 4.18.3?

I’ve been working on a game and have gotten a lot into it built around 4.18 plugins and it would be a ton of work to migrate just to allow oculus users the option of steamvr vs oculus plugin. But honestly due to the popularity of mixed reality streaming apps using openvr the requests is high on the list.

Hi, cant get to GITHUB link. Even though Im logged in.
Could you share again?

Still shows up at 404 for me
