Multiple active cameras for 1 player

Hmmm ok have you this as rendering plugin or as engine extention? Is this a supported Feature or did wrote the code behind the stereo renderer by yourself? Cause i am trien to do something similiar with quad buffering stereo

cheers

If you’re talking about “Instanced Stereo Rendering”, it’s a relatively new feature of the UE4 engine, added in 4.11, specifically for VR, which improves performance.

Hi, this my function to place window in my second monitor…

void SetFullScreenMode()
{
	int32 MonitorIndex = 1;
	FDisplayMetrics Display;
	FDisplayMetrics::GetDisplayMetrics(Display);

	GameWindowLocation = FVector2D(-Display.MonitorInfo[MonitorIndex].NativeWidth, 0);
	GameWindowSize = FVector2D(Display.MonitorInfo[MonitorIndex].NativeWidth, Display.MonitorInfo[MonitorIndex].NativeHeight);

	GameWindow.Pin()->ReshapeWindow(GameWindowLocation, GameWindowSize);

	FSystemResolution::RequestResolutionChange(Display.MonitorInfo[MonitorIndex].NativeWidth, Display.MonitorInfo[MonitorIndex].NativeHeight, EWindowMode::Fullscreen);
}

Now,
I’m not finding a role and as I do so soon after the game begins I can leave the window MainUI focused …

Are you able to render both windows as Fullscreen window mode?

Hi, this is my source

http://codepaste.net/rnderr MainUI

http://codepaste.net/kotyjy GameManager

Longer works I believe we can still do better …

I use a function that takes the monitor list and then use the space of the main monitor minus the space of the second monitor to position the second window in the second monitor …

To use this code get a DropBox project in https://drive.google.com/file/d/0BxObmjUEdjmiZm9mVmRJS1FaTTA/view and adapte files to my files…
I’m still trying to create a version for plugIn that is on GitHub

More specific in this lines…

if (!isEditor)
 {
  FDisplayMetrics Display;
  FDisplayMetrics::GetDisplayMetrics(Display);
  int32 PrimaryScreenX = Display.PrimaryDisplayWidth;
  int32 PrimaryScreenY = Display.PrimaryDisplayHeight;
  Window->ReshapeWindow(FVector2D(0, 0), FVector2D(PrimaryScreenX, PrimaryScreenY));
  FSystemResolution::RequestResolutionChange(PrimaryScreenX, PrimaryScreenY, EWindowMode::Fullscreen);
}

I have used in full screen only when it is compiled the project in Package or Debug game to not get very nasty when I’m using the editor …

Ok thanks crash i am trien this again for some reason it did not work in the past at my beamer setup but at my setup at home with 2 monitors it did

Nope I meant the renderer you were talkin about in order to help you. Quadbuffering is something different as well.

Does this work with two windows in fullscreen mode? where do you call the methode get fullscreen?

Do you might know why this is stuttering in launch mode but working flawless in any simulation mode but standalone?

@chaosgrid;567643

I think you have motion blur activated. Motion blur does not work with this, just deactivate it. (check your post processing volume and/or deactivate it via console command)

[CrashAngel]

Fullscreen set here: EWindowMode :: Fullscreen

[anonymous_user_5d8c2ae0]

… i know that but does it work with two windows set to fullscreen on your set up ?

[anonymous_user_5d8c2ae0]

I could solve all my problems on my own by now.
I just adjusted your code and googled much to avoid crashes.
Its only about achieving quadbuffered stereo now. VRPN is allmost finished as well. When I have put all together i will upload a little demo video of what i achieved.

[chaosgrid]

I tried to make the window maximize itself automatically at start but sadly that crashes in packaged builds (starting out of the project works).

OMG, I’ve been searching for something like that for ages! Do you know if it can be used as part of a VR game? Will the “hack” still work in that case?

This could allow us to make VR games like what you see on PlaystationVR, multiplayer asymmetrical mixed VR games. Games where 1 player is playing from inside VR, with the VR HMD on and controllers, while another player is playing near them on the same computer, but using the keyboard and PC monitor to interact, possibly using this ExtraCamWindow plugin!
Or you could have 1 person in VR, while other players outside make choices or have control over the experience, from options/control on the monitor view. Like a scary party game where your friends have control over the haunted house while ur playing. heh

I’ve been asking the UE4 devs for some features to allow us to customize the default HMD Mirror Window, or display other cameras on it, but this might work fine too! Thanks for making it either way.

EDIT: I probably did something wrong… When I try to drop this plugin into a project, I get this error:
Missing or incompatible modules in ExtraCamWindow plugin - would you like to disable it? You will no longer be able to open any assets created using it.

And then this error:
Plugin ‘ExampleDeviceProfileSelector’ failed to load because module ‘ExampleDeviceProfileSelector’ could not be found. Please ensure the plugin is properly installed, otherwise consider disabling the plugin for this project.

I wonder if maybe it’s a conflict with certain VR rendering features… hmm

Yes, I specifically made this to be used with a VR project. If you still have this problem, get Visual Studio 2015 (it’s free) and then add code to your project. This will cause the plugin to be built as well and then it should definitely work.

yes, my project startup 2 monitor in fullscreen…

[anonymous_user_5d8c2ae0]

if you still interested in what i am doing here is a little demo:

[CrashAngel]

Hi All,

I realized that the entire game window content begins to vibrate very little … why? I already I disabled motion blur in the Extra Window camera and Project Settings / rendering …

[CrashAngel]

Hi All…

I ended up doing a hackfix by Schlabbermampf from (https://drive.google.com/open?id=0Bx...m9mVmRJS1FaTTA ← MainUIWindow-Project)

and Creating a plugin to use a second window in unreal… In my case I still need to use the motion blur … and with this code game screens end up working properly … I will leave my code for those who want to use …

Hey guys, excellent thread! I used some of the info, did some debugging work and managed to get specific cameras to render in a new window.

I made a simple plugin for it, grab it here: GitHub - chaosgrid/ExtraCamWindow: A simple Unreal Engine 4 plugin that allows to have extra game windows with their own camera viewpoints.

Works with UE 4.12 but also 4.11 I think, not sure about older versions.
It’s mostly a hack so use with care.

Cheers!

Hey mate, any chance on getting this with a GPU affinity selection? ;D

Works great btw.

Seems to be something with AA, I changed it over to FXAA and it seems fine.

Thank you for the work!! I’m trying to build it with UE 4.13, the scene is clear when I run it, but when I rotated the scene with mouse control, the scene became blured like this

I’ve toggled off motion blur and render in FXAA. Do you probably know what kind of problem it is?

Cool plugin! Any chance you have a version working with 4.13? Thanks!
