GLTF Mesh Optimizer Tool

Effortlessly create and optimize Levels of Detail (LODs) for your GLTF models  with just a few clicks.   Made for older game engines and frameworks that do not have LoD support, like libGDX.

Key Features

• Automated Mesh Optimization: Models are optimized automatically upon import, enabling more efficient rendering on your GPU.
  
• Automatic LOD Generation: LODs are generated instantly on import with a default configuration suitable for most use cases.
• Simple Export: Export all LODs as separate GLTF files, enabling easy LoD generation for game frameworks that lack built-in LOD solutions, like libGDX .
• Customizable LOD Settings:
  • Configure 3 to 8 LOD levels.
  • Adjust the simplification factor for precise control.
  • Set a target error to balance quality and performance.
• WebP Texture Encoding: Optionally encode textures as WebP images to reduce asset sizes, with a minimal runtime memory trade-off.  Note: your game engine/framework requires EXT_texture_webp GLTF support.
• Permissive Simplification: Enable advanced mesh simplification to preserve visual quality while significantly reducing complexity. Learn more here.
• Preview and Validation: Fully preview all LODs before exporting, with a toggleable wireframe view for detailed inspection.
• Industry-Standard Technology: Built on the robust meshoptimizer library (v0.25) for reliable performance.

How to Use

1. Import your GLTF model, and the tool automatically optimizes the model and generates LODs.
2. Optionally adjust LOD settings as needed, then click RE-GENERATE to apply changes.
3. Select EXPORT from the ACTION menu to save LODs as separate GLTF files.
