(OUTDATED, SEE DESCRIPTION FOR NEW VERSION) Create Large Scale Oceans in Blender 2.8

THIS TUTORIAL HAS BEEN UPDATED FOR BLENDER 2.93. PLEASE GO HERE INSTEAD:
Large Scale Oceans in Blender with FOAM!

In this tutorial you'll learn how to use the ocean modifier in Blender to generate displacement maps which can then be combined into a custom ocean shader enabling you to render large scale oceans without breaking your computer.

Requirements
Blender 2.80+
