UE5.1 - textures not rendering correctly in packaged game

Development Platform & Builds

Hi, I have loaded my Paper2D (C++) game from UE4.27 into UE5.1 and it runs ok within the editor.

When I package up the game for Windows, a white screen is shown so I can’t see the game, although some textures appear but are not rendered correctly and the game does not run well and runs very slow! This is also true if I run the game in development mode within Visual Studio after cooking the content.

Any ideas anyone?

Hey @Manjinder70,
Is there any way you could provide some screenshots of what you’re doing, and what’s happening?
Thanks!

Hey, I’ve also been having some significant issues with packaged textures in my game from unreal 4 to 5.1, what helped me is turning to antialias on to TXAA and disabling lumen although it never fully resolved the issue. Is your game throwing any cooked errors? And maybe try to make sure all your lighting is set to moveable.

Thanks, I’ve been doing some more investigation.

I have created a blank C++ project with no starter content and just spawn one actor which simply prints the frame rate as debug to the screen.

Now when I package this and run it, I get a chequered floor with the mountain terrain. Why is this? Can I turn off this content? I just want a black empty screen.

The FPS is also only around 9!
