AutoLOD - Mesh Decimator

AutoLOD is a powerful tool to simplify any mesh from your scene in one click. It also comes with a runtime API to bring the decimation feature in your builds!

AutoLOD 5.1 : Now supports Blendshape on both Fast and High Quality backends!

• Elevate Your Experience with the brand new 'High-Quality' Backend: It is not just another update – it's a game-changer that will redefine your expectations.
• Best UV Layout Preservation: Experience the most precise UV layout preservation yet. The High-Quality backend ensures your textures still align perfectly after decimation, maintaining the artistic integrity of your models.
• Mesh Borders Preserving: Say goodbye to collapsed border edges. The High-Quality backend makes sure your chunks will still fit together nicely after decimation.
• Unmatched Simplicity: This update keeps the user-friendly simplicity that has won over thousands of users. One click is all it takes.
• Editor and Runtime usage: Work seamlessly with both the editor plugin or the C# runtime API. AutoLOD flexible design adapts to your workflow, not the other way around.
• Prefab-Friendly: 100% compatible with prefabs. There's no need to unpack them – AutoLOD works directly with prefab instances or in prefab editing scenes.
• Characters-Friendly: Skinned Mesh Renderer and Blendshapes full support.
• Multi-Level LOD Generation: Push the limits with up to 8 levels of LOD for a single object, ensuring optimal performance across a range of distances and complexities.
• Submesh Compatibility: AutoLOD seamlessly works with submeshes.
• Performance-Fidelity Balance: Find the perfect balance between high performance and high-fidelity results with the customizable options.
• Distance Culling Simplified: Ideal for simple distance-based culling too.

Technical details

• Works on any render pipeline natively
• Editor Window based on IMGUI (no dependencies)
• Decimation core in packed into a DLL (not the editor window) for these reasons:
  • The decimation core contains hundreds of files. 1 file will be more appreaciated in most projects
  • It makes updates easier and safer. Since AutoLOD is in perpetual evolution, we may add and remove files from the core every few updates. No conflict is possible since a single file is entirely replaced (it is not possible to delete an old file when making a unity package, and leaving dozens of blank files is not very elegant)
  • It clusters more notiecably software scopes between the user's code and the decimation API.
  • The core is almost 100% unity-independant (except from the UnityEngine.Mesh class) meaning that it most likely won't break with any unity update anytime soon.
