A two-window (camera) application possible?

Hello dear Unreal Engine professionals.

I have a very special request and wonder if it can be realised with unreal engine at all.

I want two windows to open when I start the programme.
Both windows should show two different camera views of the same game.
This means that all changes that happen in one window should also happen in the other.

Thank you for help

Why do you want two different applications running when you can just have one application with multiple viewports? If viewport is what you meant then just do:

Windows → Viewports → Viewport 2

But I would like to make a programme in Unreal that has a view of the object with two cameras when you start the exe.

Buy it, or google for: “unreal split screen”

But also in two windows…

Ahh so you want two separate applications running.

Then only local multiplayer.

I think single game/project made on unreal can only have single window.

However there is multi display support, but i am unsure about it.

Edit:
Yes there is:

nDisplay thingy.

is not what im searching for…
I want just one Unreal Engine Application who run two Windows which shows the same level. And replications is also no good enove.

Choices that i know about:

  • split screen on single PC and single monitor
  • multiplayer with each client rendering on separate screen, can all be running on same PC. Essentially self made primitive nDisplay
  • nDisplay, bit complicated, but it has everything you want, can run from single PC, with separate instances rendering to separate screens.

I do not think there are other ways to render on separate screens.

Okay, thank you very much for your time.

My biggest problem right now is that I have two windows and also two same things are displayed but they are not updated the same. Either only the server or the client shows the change.

Short recap of my programme:
I have music frequencies analysed.
These change values of a dynamic material
And this change should be displayed on both windows.
But it does not.

The Ball right should also glow and deform.

You need to replicate data that drives material. Then set material parameters on server and on clients.

However that may be a bit much for bandwidth.

Read about nDisplay, if anything can do this, its nDisplay.
