UGameplayStatics::SetEnableWorldRendering

function Engine Blueprint Since 4.0

#include "Kismet/GameplayStatics.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Enables or disables rendering of the entire game world. Disabling rendering can reduce GPU load in scenarios where only UI output is needed, such as dedicated-server-like clients.

Caveats & Gotchas

• Disabling rendering does not pause the game or stop ticking — actors continue to run. Only the viewport draw calls are skipped.
• UI drawn directly to the HUD (via Canvas) is also suppressed because it shares the scene rendering pass. Use Slate/UMG widgets with separate render passes if you need to show UI while the world is hidden.
• This is a viewport-level toggle; it affects all local viewports. It cannot be applied per-player in splitscreen.
