# Ramp 4 Corners

A four-point linear value ramp (gradient) generator.

## Parameter Types

Parameter Types Parameter descriptions Discussion This node uses bilinear interpolation to create a ramp from four corner values. Any point within the output ramp is a mix of one of the four corner values. A given point is more similar to a corner value the closer its position is to that corner. Below is a an example of a simple node graph that uses Ramp 4 Corners to create a gradient with four different colors:

The image below shows the resulting texture along with the color values on each corner:
