The window being captured isn't showing. When a window isn't existing, I'm assuming it shows the white material. But when I change the property to a window that exists, it now shows a black material. What could be the problem?

UE Version: 4.27.2

Hello, I am a VR developer, and i've been using windowcapture2D plugin for my projects - however since the last 3 days whenever i try to install windowcapture2D it never shows up in my projects. It is listed as enabled in plugins however. Turning it off and on again doesn't work, restarting the engine doesn't work, uninstalling and reinstalling doesn't work, and neither does reinstalling the engine. Using UE4 26 worked - but my project is built for steamVR - so it is based on UE4 23.1 only.

Not sure how to fix this - i've spent a few days on it already, and i am going to have to look for another plugin at this point :/

Start Windows application file (* .exe) from UE4

hello,

the plugin is working perfectly for us in editor mode.

however, in shipping mode, the captured window is "cropped" and only a part of it is visible.
on the right and bottom, there are big black bars.

is this a known issue?
should I post more information on the issue?

Engine Version is 4.23.1

thank you in advance,
ed

btw: we offer a donation on that issue.

I found that UE4 crashes with EXCEPTION_ACCESS_VIOLATION when CheckWindowSize is checked and repeated resizing of the target window.

Reproduction steps

1. Create New UE4.24.2 project and enable WindowCapture2D plugin
2. Place WindowCapturePlane in the world
3. Check CheckWindowSize and change CaptureTargetTitle on WindowCapturePlane
4. Play the project
5. Resize target window repeatedly

Crash message is

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x08cad000

It crashes - both in the editor (upon endplay) and on a package game. (something about UpdateTexture)

When ran as a packaged project it says
Plugin WindowCapture2D failed to load because module WindowCapture2D could not be found. Please ensure the plugin is properly installed, otherwise consider disabling the plugin for its project.

I very much need this plugin for my project therefore I cannot disable the plugin.

The plugin will sometimes cause the Unreal Editor to crash. Unfortunately, few additional details can be provided. Steps to reproduce:

• Add WindowCapturePlane from PlaneActor content folder to level;
• Change the properties so that it captures the content of some window (e.g., a browser window), I choose Partial Match;
• Play the level within Editor. Switch to browser window, introduce some changes;
• Come back to Editor, press ESC on the keyboard to stop playing the level;
• Sometimes at this point the Editor will crash.

The texture target is deleted at a time when the docapture is running in another thread during close.

This causes crashes in the renderer as the texture gets killed during render. As it's multithreaded this is occasional.

Changing the close order to below is better as it kills the thread before destroying the texture. Also the texture needed nulling.

```

if (CaptureThread)
{
CaptureThread->Kill(true);
CaptureThread->WaitForCompletion();

	delete CaptureThread;
	CaptureThread = nullptr;
}
if (TextureTarget)
{
	TextureTarget->ReleaseResource();
	TextureTarget = nullptr;
}

My notebook have RTX 3080 and Ryzen 9 5900HX APU.
When I set high performance graphics adapter for UE4 my project's performance is good but I can not get any captured texture it gives totally black screen. I need to switch power saving mode but when I do it performance significantly decrease. Actually this is a general issue for OBS, Zoom and any other capture screen tools.

But this is an UE4 plugin. So, high performance is important.
Can you fix it ?

btw Unreal Market place link does not work.
