Software used

MARI v2.0v1, UDK July 2013

What you will learn

In this series of tutorials, we will learn how to create and utilize flow maps to create a water shader

in UDK.

We will start by discussing what a flow map does and how it can give your water shaders an extra boost

in quality. Then we'll create a level proxy and water plane for the artist who will be creating the

flow map in MARI.

From there, we will take you through the process of creating the flow map in MARI. You will learn how

to set up your MARI project, how to paint and nudge your flow map, how to utilize the Vector Inspection

Grid to assist in painting flow, and how to scale the flow vector to control intensity. You will finish

up with by learning how to export your flow maps to be used in UDK.

Then we'll wrap up the training by jumping back into UDK and learn how to set up a water shader that

will utilize our MARI created flow map.
