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. Software required: MARI v2.0v1, UDK July 2013.
Joshua is a devoted games author at Pluralsight. For years Joshua was a key author behind Digital-Tutors' (now a Pluralsight company) popular game engine training. As a kid, he had a passion for playing video games, which eventually developed into a fascination with the process of game creation. The question of "How'd they do that?" led Joshua on a quest to learn to make these games himself. Ever since then, Joshua has devoted his life to creating games, as well as teaching others to build their own fantastic video games.
