Incredibly inefficient and slow operation! Read a value as sRGB color from a render target using UV [0,1]x[0,1] coordinates.

Syntax

static FColor ReadRenderTargetUV
(
    UObject * WorldContextObject,
    UTextureRenderTarget2D * TextureRenderTarget,
    float U,
    float V
)

Remarks

Incredibly inefficient and slow operation! Read a value as sRGB color from a render target using UV [0,1]x[0,1] coordinates. LDR render targets are assumed to be in sRGB space. HDR ones are assumed to be in linear space. Result is 8-bit per channel [0,255] BGRA in sRGB space.
