Description

Converts a HSV color packed into a FLinearColor (R=H, G=S, B=V) to linear RGB, writing the result into a second FLinearColor. This vector form avoids breaking the HSV triple into separate floats and is convenient when working with colour data already stored in FLinearColor.

Caveats & Gotchas

• The mapping of H/S/V onto R/G/B channels of a FLinearColor is non-obvious: H is in R (0–360), S in G (0–1), V in B (0–1). A FLinearColor constructed from MakeLinearColor will NOT produce correct results unless you manually assign channels with this channel ordering.
• The alpha of the input HSV FLinearColor (A channel) is carried through to the output RGB FLinearColor unchanged — it is not treated as part of the HSV data.

Signature

static UE_INL_API void HSVToRGB_Vector(FLinearColor HSV, FLinearColor& RGB)

Parameters

Name	Type	Description	Default
HSV	FLinearColor	A LinearColor used as a packed HSV triple: R = Hue [0..360), G = Saturation [0..1], B = Value [0..1]. The A channel is copied through to output.A.	—
RGB	FLinearColor&	Output: the converted linear RGB color.	—

Return Type

void

Example

Convert a packed HSV FLinearColor to RGB C++

FLinearColor HSVPacked(180.0f, 0.8f, 0.9f, 1.0f); // cyan-ish
FLinearColor RGBResult;
UKismetMathLibrary::HSVToRGB_Vector(HSVPacked, RGBResult);
