UKismetMathLibrary::Conv_LinearColorToColor

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Converts a FLinearColor to an 8-bit FColor, optionally applying sRGB gamma encoding. This is the standard path for converting engine linear colors to display-ready 8-bit values, for example before storing in a texture or passing to a UI widget.

Caveats & Gotchas

• With InUseSRGB = true (the default), values > 1.0 are clamped before encoding — HDR linear colors will clip. If you need to preserve HDR data use LinearColor_ToRGBE instead.
• InUseSRGB = false performs a raw floor-to-byte without gamma, equivalent to LinearColor_Quantize. Most display surfaces expect sRGB encoding, so passing false will produce colors that appear too dark on screen.

Signature

static UE_INL_API FColor Conv_LinearColorToColor(FLinearColor InLinearColor, bool InUseSRGB = true)

Parameters

Name	Type	Description	Default
InLinearColor	FLinearColor	The linear-space color to convert.	—
InUseSRGB	bool	When true (default), applies sRGB gamma encoding before quantizing to 8-bit. When false, quantizes directly without gamma correction.	true

Return Type

FColor

Example

Convert a linear color to an 8-bit sRGB FColor for texture writing C++

FLinearColor LinearBlue(0.0f, 0.2f, 1.0f, 1.0f);
FColor SRGBBlue = UKismetMathLibrary::Conv_LinearColorToColor(LinearBlue, true);
// SRGBBlue is now ready for texture pixel writes or UI use
