Lerp

Mon, 01 Jan 0001 00:00:00 +0000

Lerp#

Inputs#

A (FLCHColor)

B (FLCHColor)

Alpha (float)

Output#

LCHColor

Behaviour#

Linearly interpolates luminosity, chroma, hue, and transparency from A to B using alpha as the interpolation value.
This interpolation happens in the OKLch Color space since both colors are LCHColors and produces different results from directly Lerping between LinearColor values.

LCHColor from LinearColor

Mon, 01 Jan 0001 00:00:00 +0000

LCHColor from LinearColor#

Input#

Color (LinearColor)

Output#

LCHColor

Behaviour#

Converts a provided LinearColor to the OKLCH color space, outputting an LCHColor. The provided color should be a linear non SRGB color, so avoid gamma correcting the color before plugging it into the input.

LCHColor To LinearColor

Mon, 01 Jan 0001 00:00:00 +0000

LCHColor To LinearColor#

Input#

Color (LCHColor)

Output#

LinearColor

Behaviour#

Converts a provided LCHColor to the linear color space, outputting a LinearColor. The color is clipped back to the SRGB color gamut when converting back so the color is displayed correctly.
Use this when you want to display your LCH Color again or set it on widgets.

LCHColor To LinearColor Fast

Mon, 01 Jan 0001 00:00:00 +0000

LCHColor To LinearColor Fast#

Input#

Color (LCHColor)

Output#

LinearColor

Behaviour#

Converts a provided LCHColor to the linear color space, outputting an LinearColor.
Color is clamped back to the SRGB color gammut when converting back, this is lossy and not always correct so only use it if you need the speed and are sure you can live with ther errors, otherwhise use LCHColor To LinearColor.
Use this when you want to display your LCH Color again or set it on widgets.

Interpret As LinearColor

Mon, 01 Jan 0001 00:00:00 +0000

Interpret As LinearColor#

Inputs#

Color (FLCHColor)

Output#

LinearColor

Behaviour#

Reinterprets an LCHColor as a LinearColor so it can be sent to a material using Set Vector Parameter Value.

Clip To SRGB Gammut

Mon, 01 Jan 0001 00:00:00 +0000

Clip To SRGB Gammut#

Inputs#

Color (FLCHColor)

Output#

FLCHColor

Behaviour#

Clips the LCHColor to the SRGB color gamut. This is usually used before converting to LinearColor, and the LCHColor To LinearColor node does this automatically.

Get Clamped

Mon, 01 Jan 0001 00:00:00 +0000

Get Clamped#

Inputs#

Color (FLCHColor)

Output#

FLCHColor

Behaviour#

Clamps the input LCHColor to the SRGB color gammut this is wrong in some cases but faster than clipping.

Get Formatted

Mon, 01 Jan 0001 00:00:00 +0000

Get Formatted#

Inputs#

Color (FLCHColor)

Output#

FString

Behaviour#

Provides a human readable output for display in consoles as an FString.
