Controlling materials and EcoSystems with the wetness index node

The wetness index node computes the amount of water across a terrain. Use it to drive material distribution and EcoSystems.

The wetness index node is a node that is supposed to be used in the function graph of a terrain. By using custom and external dependencies, you can then reference the output of this node inside of a material graph and drive EcoSystem distributions and material layer presences with it.

In this tutorial, Barry Marshall shows how to utilize custom dependencies and how to get the most out of the wetness index.
