UKismetRenderingLibrary::CreateRenderTarget2DArray

function Engine Blueprint Since 5.0

#include "Kismet/KismetRenderingLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Creates a new 2D render target array with the given number of slices and initializes it to the specified dimensions.

Caveats & Gotchas

• Not every RHI/platform supports render target arrays; check hardware support before relying on this in a shipping title targeting lower-end platforms.
• Memory scales linearly with Slices — a large array of high-resolution slices can exhaust GPU memory quickly.
• As with CreateRenderTarget2D, the caller must hold a reference to the result or it is eligible for garbage collection.

Signature

static UTextureRenderTarget2DArray* CreateRenderTarget2DArray(UObject* WorldContextObject, int32 Width = 256, int32 Height = 256, int32 Slices = 1, ETextureRenderTargetFormat Format = RTF_RGBA16f, FLinearColor ClearColor = FLinearColor::Black, bool bAutoGenerateMipMaps = false, bool bSupportUAVs = false);

Parameters

Name	Type	Description	Default
WorldContextObject	UObject*	Object used to resolve the current world.	—
Width	int32	Width of each slice in pixels.	256
Height	int32	Height of each slice in pixels.	256
Slices	int32	Number of array slices to allocate.	1
Format	ETextureRenderTargetFormat	Pixel format of the render target array.	RTF_RGBA16f
ClearColor	FLinearColor	Default clear color used when the target is cleared.	FLinearColor::Black
bAutoGenerateMipMaps	bool	Whether mips are generated automatically after rendering.	false
bSupportUAVs	bool	Whether the render target's resource supports unordered access views for compute shader writes.	false

Return Type

UTextureRenderTarget2DArray*

Example

Create a 4-slice array C++

UTextureRenderTarget2DArray* RTArray = UKismetRenderingLibrary::CreateRenderTarget2DArray(this, 512, 512, 4, RTF_RGBA16f);
