Syntax
class UTextureRenderTarget2D : public UTextureRenderTarget
Remarks
TextureRenderTarget2D
2D render target texture resource. This can be used as a target for rendering as well as rendered as a regular 2D texture resource.
Variables
Type | Name | Description | |
---|---|---|---|
![]() |
TEnumAsByte< enum TextureAddress > | AddressX | The addressing mode to use for the X axis. |
![]() |
TEnumAsByte< enum TextureAddress > | AddressY | The addressing mode to use for the Y axis. |
![]() |
uint8: 1 | bAutoGenerateMips | Whether to support Mip maps for this render target texture |
![]() |
uint8: 1 | bForceLinearGamma | True to force linear gamma space for this render target |
![]() |
uint8: 1 | bGPUSharedFlag | Whether to support GPU sharing of the underlying native texture resource. |

![]() |
TEnumAsByte< enum TextureAddress > | MipsAddressU | AutoGenerateMips sampler address mode for U channel. Defaults to clamp. |
![]() |
TEnumAsByte< enum TextureAddress > | MipsAddressV | AutoGenerateMips sampler address mode for V channel. Defaults to clamp. |
![]() |
TEnumAsByte< enum TextureFilter > | MipsSamplerFilter | Sampler filter type for AutoGenerateMips. Defaults to match texture filter. |
![]() |
TEnumAsByte< enum EPixelFormat > | OverrideFormat | Normally the format is derived from RenderTargetFormat, this allows code to set the format explicitly. |

![]() |
int32 | SizeX | The width of the texture. |
![]() |
int32 | SizeY | The height of the texture. |
