UKismetMathLibrary::LinearColor_Quantize

function Engine Blueprint Deprecated Since 4.0

Deprecated: Use LinearColor_QuantizeRound instead for correct color conversion.

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Quantizes a FLinearColor to an 8-bit FColor by truncating each channel (floor), bypassing sRGB gamma conversion. Deprecated — use LinearColor_QuantizeRound for correct color rounding.

Caveats & Gotchas

• This function is deprecated. The Blueprint node shows a deprecation warning. Use LinearColor_QuantizeRound instead, which rounds rather than truncates, producing more accurate 8-bit representations.
• Because it bypasses sRGB gamma, the result looks darker than expected when displayed on a typical monitor. Only use this if your target explicitly expects raw linear-to-byte truncation (which is rare).

Signature

Parameters

Name	Type	Description	Default
InColor	FLinearColor	The linear color to quantize to 8-bit values.	—

Return Type

FColor

Example

Legacy quantization (prefer LinearColor_QuantizeRound instead) C++

// DEPRECATED — prefer LinearColor_QuantizeRound
FLinearColor Lin(0.5f, 0.5f, 0.5f, 1.0f);
FColor Legacy = UKismetMathLibrary::LinearColor_Quantize(Lin);
// Legacy.R == 127 (floor of 0.5*255), not perceptually mid-grey
