6	Model Optimization	Graphics	Model	Graphics/Model

Model optimization generally starts from the following points:

• Mesh: Reduce the number of vertices and faces, compress mesh data
• Texture: Adjust texture size (e.g., from 1024 * 1024 -> 512 * 512), use compressed textures
• Animation: Compress animation data

Best Practices

In the editor, we can optimize the model in the following ways:

1. Use Quantize to compress mesh data. When exporting the project, check the GlTF Quantize option to quantize and compress the mesh.
2. Use Meshopt to further compress mesh data.

Compression may affect the precision of the model mesh, but in most cases, it is difficult to distinguish with the naked eye.
