HLOD system
It can replace multiple Static Mesh Actors with single, combined Static Mesh Actor at long view distances. This helps reduce the number of Actors that need to be rendered for the scene, increasing performance by lowering the number of draw calls per frame.

Prerequisites
Unity
Unity Version: 2021.3.3f1
Currently, I developed in 2021.2.19f1. Probably it works on the 2020.3 but I can't guarantee.
Git
You need Git Client which can work with GitHub.
If you don't have Git installed on your machine, download and install it from Git Home.
Connecting to GitHub with SSH
To clone the project, your Git must be configured to work with SSH Authentication, as HLODSystem uses SSH Authentication to work with Git Submodules. Check this link to set up your git to use SSH to connect to GitHub.
