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

Name Description

Public variable

TEnumAsByte< en...

 

AddressX

The addressing mode to use for the X axis.

Public variable

TEnumAsByte< en...

 

AddressY

The addressing mode to use for the Y axis.

Public variable

uint8: 1
