Build-in effects - Monochrome

Last edited 2026-02-27

The effect returns the luminance from the colors of the main texture.

Input data:

• Self (Main texture of the object/layer, depending on where you apply the effect; contains information about Red, Green, Blue, Alpha)

Output data:

• Render (Red, Green, Blue, Alpha colors that will be displayed on the screen)

Example written in pseudocode:
load float4 Self;                                                                // LOAD main texture

float4 Render;                                                                // Create an empty variable

float3 Mono = float3(Self.rgb) * float3(0.299f, 0.587f, 0.114f);        // Assign the luminance value from Self to a new variable

Render.rgb = Mono.r + Mono.g + Mono.b                                        // Assign the sum of luminance from the colors R, G, B
Render.a = Self.a;                                                                // Assign the Alpha color from Self to Alpha

return Render;                                                                // Return the Render
