Automatic LOD is a Unity extension that simplifies the process of creating and managing multiple levels of detail for 3D models. It generates procedurally simplified meshes, known as LOD levels, which help optimize game performance, especially on lower-end platforms. The extension also automatically switches between LOD levels based on the object's distance to the camera or screen area covered, ensuring that detailed meshes are only used when necessary.
The Automatic LOD component is easy to use and requires no scripting. It includes a clean and intuitive UI with multiselection support, live preview in edit mode, and the ability to fine-tune the LOD generation process. The extension also supports complex object hierarchies, multiple materials, and both screen coverage and distance to camera algorithms.
Key features include:
- Procedural generation of LOD levels with one click
- Support for static and skinned meshes
- Automatic LOD handling with no scripting required
- Includes full source code and high-quality 3D models
- Works at runtime and supports live preview in edit mode
- Valid for all platforms, especially useful on mobile
- Handles complex object hierarchies and multiple materials
- Supports screen coverage and distance to camera algorithms
- Allows fine-tuning of LOD generation
- Includes classic mesh decimation/polygon count reduction using the Mesh Simplify tool
The Automatic LOD extension is built on top of the Mesh Simplify extension, which is also included. It uses a combination of algorithms to generate LOD levels, including screen coverage and distance to camera algorithms. The extension supports both static and skinned meshes and can handle complex object hierarchies with sub-objects and multiple materials.
