Vertex-color blending ​

The following sections contain examples on how to blend colors using vertex-colors. It is recommended to read Shading network concepts before proceeding.

Vertex-color blending using InterpolateNode ​

This script sets up three vertex color nodes where the last one is used as blend weight. This example is based on the InterpolateNode.
