Shader Type: Math (Tool)
Output: Color (RGB) value
Used to perform basic mathematical functions between two input colors, shaders, or textures.
Name |
The shader’s name. Enter any name you like, or leave the default. |
Input 1 |
Defines the first color, shader, or texture. |
Input 2 |
Defines the second color, shader, or texture input. |
Operation |
Performs a basic mathematical function using both input colors. Add: Simply adds the two colors together. Subtract: Subtracts input 2 from input 1. Multiply: Simply multiplies the two colors together. Values will not be clipped at 1. Divide: Divides input 1 by input 2. Minimum: The output will be the lowest R, G, B, and A values of both input colors. For example, if input 1 has a 0.75 G value and input 2 has a 0.45 value, the shader will use input 2’s G value. Maximum: The output will be the highest R, G, B, and A values of both input colors. For example, if input 1 has a 0.85 R value and input 2 has a 0.55 value, the shader will use input 1’s R value. |
Apply to Alpha |
Uses an input alpha as RGB values. |
Used to connect one or two shaders (textures, materials, other math shaders, etc.) to the Input parameters. Once a function is selected, the output can be used on any shader that accepts a color input.
