Generate LODs
Create LOD0–LOD3 levels of detail from one GLB or glTF model for Unity, Unreal and Three.js. Preview each level, then download one or all as a ZIP. Runs in your browser. Takes FBX too, converted to GLB in your browser.

- Game ready
How to generate LODs for a 3D model
Generate LODs creates several levels of detail from one GLB or glTF model. Each level has fewer triangles than the last, so a game engine or 3D viewer can show a lighter mesh when the object is far away and keep the frame rate up.
Pick a Standard, Aggressive or Minimal preset or set your own targets, preview each level, and download them individually or together as a ZIP. It runs in your browser with nothing uploaded.
Step by step
- Drop a .glb or .gltf model onto the page.
- Choose a preset or set the reduction for each level.
- Preview each LOD and its triangle count.
- Download one level or all of them as a ZIP.
Questions
What are LODs?
Levels of detail (LODs) are simpler versions of the same model. LOD0 is the full-detail original; LOD1, LOD2 and so on have progressively fewer triangles and are shown as the object gets further from the camera.
How many LOD levels do I need?
Three or four levels is common for game assets. Small props may need only two, and very large or frequently repeated objects benefit from more.
How do I use the LODs in Unity, Unreal or Three.js?
Import each level into your engine and assign them to its LOD system: a LOD Group in Unity, the LOD settings on a static mesh in Unreal, or THREE.LOD in Three.js.
