UKismetRenderingLibrary::CreateRenderTargetVolume

function Engine Blueprint Since 5.0

#include "Kismet/KismetRenderingLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Creates a new volume render target and initializes it to the specified 3D dimensions, typically for volumetric effects written via compute shaders.

Caveats & Gotchas

• Volume render targets are memory-hungry — Width * Height * Depth texels at the chosen format, so doubling any dimension octuples cost relative to all three.
• Writing to a volume target usually requires bSupportUAVs = true and a compute shader; there is no Blueprint-only path to populate one meaningfully.
• Default dimensions (16x16x16) are intentionally small — most real usage needs to set explicit dimensions matching the intended volumetric effect.

Signature

static UTextureRenderTargetVolume* CreateRenderTargetVolume(UObject* WorldContextObject, int32 Width = 16, int32 Height = 16, int32 Depth = 16, 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 the volume in texels.	16
Height	int32	Height of the volume in texels.	16
Depth	int32	Depth of the volume in texels.	16
Format	ETextureRenderTargetFormat	Pixel format of the render target.	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

UTextureRenderTargetVolume*

Example

Create a volume target for a compute shader C++

UTextureRenderTargetVolume* VolumeRT = UKismetRenderingLibrary::CreateRenderTargetVolume(this, 32, 32, 32, RTF_R16f, FLinearColor::Black, false, true);
