Build-in effects - OR

Last edited 2026-02-27

This effect uses bitwise OR on the base layer and top layer.

Input data:

• Self (Main texture of the object/layer, depending on where you apply the effect; contains information about Red, Green, Blue, Alpha)
• Background (Second texture that contains information about Red, Green, Blue, Alpha* pixels that are underneath Self)

Output data:

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

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

int3 Base = int3(Self * 255.0f);                        // Assign Self colors to Base, with a conversion from float to int.
int3 Blend = int3(Background * 255.0f);                // Assign Self colors to Blend, with a conversion from float to int.

int3 Color = Base | Blend;                                // Apply OR operation to Base and Blend and assign to Color

float4 Render;                                        // Create an empty vector

Render.rgb = float3(Color) / 255.0f;                // Assign the result of the R, G, B color conversion from int to float.
Render.a = Self.a;                                        // Assign the Alpha color from Self to Alpha

return Render;                                        // Return the Render

Examples of recreation effects created by the community:

1. OR by Cezra; It does the same shader.
2. Logical OR (Background) by Foxioo; It is a modification of the effect created by Cazra, adding more options for modifying the output color.
