One-Click LOD Generator for Blender — Documentation

Overview

The One-Click LOD Generator is a lightweight and user-friendly Blender addon that automates the creation of Level of Detail (LOD) models for your assets. With just one click, it generates 4 levels of LODs, names them automatically, groups them under a clean hierarchy, and optionally exports them as FBX files — perfect for game developers, AR/VR creators, and anyone needing optimized 3D workflows.

Key Features

• One-click LOD creation (LOD0 to LOD3)

• Custom decimation ratios for each LOD level

• Automatic naming: YourObject_LOD0, _LOD1, etc.

• LOD hierarchy grouped under a parent Empty

• Optional FBX export to /LODs/ folder

• Clean UI under the "LOD Tools" tab in the sidebar (N panel)

Use Cases

• Game asset LOD generation for Unity, Unreal, Godot

• WebGL and AR/VR performance optimization

• Batch exporting and automation of optimized assets

• Creating lightweight preview versions of complex models

Installation

1. Download the one_click_lod_generator.py file.

2. In Blender: go to Edit > Preferences > Add-ons > Install.

3. Select the .py file and enable the addon.
