VR mode fullscreen is not work using htc vive?

Hi,I’m using htc vive.
When I play game in vr mode,‘fullscreen’ command does not take any effect,‘ALT+ENTER’ also is not work.
It always has two sides of black block.
But when I play game in ‘standalone’ mode ,it is right.However, the hmd of htv vive not work,even if i set ‘enable hmd’ true.
Who can give me some help?
I want to record the game! It is so important!

Is there any one knows ?Maybe, there is another way, to change the resolution of vr in screen?

would like to know a solution to this too!

See this post Problem about monitor resolution display in vive vr mode - XR Development - Unreal Engine Forums, you have to edit SteamVRRender.cpp in the source code

Very thanks,it is very useful! But,how can i debug the plugin? I set a breakpoint in it SteamVRRender.cpp, it does not hit?Maybe it is another question! can you give me some help?

Hi,do you have some idea? I do not have the source code of the engine! I also recompile it, it is not work also!

For me it didn’t require debugging or anything. I just opened up SteamVRRender.cpp and changed mirrormode=1 to this:

RendererModule->DrawRectangle(
RHICmdList,
0, 0,
ViewportWidth, ViewportHeight,
0.0f, 0.3f,
0.4f, 0.4f,
FIntPoint(ViewportWidth, ViewportHeight),
FIntPoint(1, 1),
*VertexShader,
EDRF_Default);

Also I am using a built of 4.12.2 from github A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums. I tried to do it with the regular install but it won’t have the ability to rebuild the engine (I what I found)

Hi, I am sorry that the link is not work now!Can you give me a newer?

It had a period at the end, sorry A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums

How/where do I access SteamVRRender.cpp? I can’t find it anywhere.

Since a lot of people still have problems with this, here is a short tutorial explaining it step by step.

Thanks for doing that man, it’s hard to explain the steps sometimes.

in the 4.17 the fixed the issue its full-screen now
