The goal of this tutorial is to provide an alternative environment system that works with Atavism without having to use the CTS shaders to control the weather. While nice, CTS and Gaia 2 (Pro) have a very large shader keyword usage and as such limit project shader usage. This will have better functionality using several new shader systems that provide better performance at less shader keyword cost.
Once completed, you will have the items needed to convert your Atavism over to these alternative weather items.
