Level of Detail

This add-on provides level of detail for meshes, lights and particles. It can be used to improve performance in large scenes significantly.

This repository only contains the add-on. See godot-extended-libraries/godot-lod-demo for the demonstration project.
Features

Supports lights, meshes and particles (Particles and CPUParticles).
Each node has its own LOD distance properties, but you can also define a LOD bias project setting to improve visual quality or performance for the target hardware.
Lights can have their shadow smoothly fade off with distance, then the light itself smoothly fade off as well.
Works with both the GLES3 and GLES2 renderers.
Written in performance-conscious GDScript. Easy to install and use, but scales to hundreds of LOD instances (and perhaps thousands on more powerful hardware).

The LOD add-on only runs in the running project, not while in the editor. This is done by design to avoid accidentally saving modified versions of the scene. You need to run the project to test LOD functionality.
