+# Optimization, LOD, and rendering work/plugins for Godot Engine 4.x and 3.x.
 ## The master branch is developed for 4.x and a 3.x branch is available for Godot 3.
-Optimization and rendering work/plugins for Godot Engine 4.x and 3.x.
 
 ## [Multithreaded LOD in C++ with "Importance" value](https://github.com/puchik/godot-extras/tree/master/gdextension/importance-lod)
 A LOD-like system which contains a LODObject that controls child LOD levels through a LODManager autoload. It calculates a discrete LOD value based on your input parameters, supports switching child nodes when a given LOD is reached, sends signals you can hook into to perform distance optimizations (like AI complexity), and calculates a float "Importance" value. Partially inspired by the [Significance Manager](https://dev.epicgames.com/documentation/en-us/unreal-engine/significance-manager-in-unreal-engine) in Unreal Engine.
