Gradient Node

Description

Defines a constant Gradient for use in Shader Graph, although internally to the shader this is defined as a struct. To sample the Gradient it should be used in conjunction with a Sample Gradient Node. When using a separate Gradient Node, you can sample a Gradient multiple times with different Time parameters.

Generated Code Example

The following example code represents one possible outcome of this node.

Gradient Unity_Gradient_float()
{
    Gradient g;
    g.type = 1;
    g.colorsLength = 4;
    g.alphasLength = 4;
    g.colors[0] = 0.1;
    g.colors[1] = 0.2;
    g.colors[2] = 0.3;
    g.colors[3] = 0.4;
    g.colors[4] = 0;
    g.colors[5] = 0;
    g.colors[6] = 0;
    g.colors[7] = 0;
