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.
