In this tutorial, I'll show you how to extract the tessellation algorithm from the Unreal Engine water system and apply it to optimize your ocean water plane or custom generated terrain. A mesh tile has a smooth transition between levels of detail, seamlessly morphing in and out with changes in camera distance. Please note that this method can only be used as a plane mesh.

This tutorial is designed to be a standalone guide, allowing you to follow the steps and get the tessellation working on your project.
