UKismetRenderingLibrary::ReleaseRenderTarget2D

function Engine Blueprint Since 4.0

#include "Kismet/KismetRenderingLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Manually releases the GPU resources of a render target instead of waiting for the garbage collector, useful when creating many short-lived render targets at runtime.

Caveats & Gotchas

• The UObject itself is not destroyed, only its GPU-side resource; using the render target afterward for drawing or reading will not work correctly until it is recreated.
• Intended for platforms with tight GPU memory budgets where waiting for GC-driven cleanup of many render targets would cause memory pressure spikes.
• Calling this on a render target that is still actively bound as an output (e.g. mid-draw) can produce rendering artifacts or a crash.
