The MeshLodUtility class allows developers to simplify geometry programmatically. This is essential for procedural tools or editor scripts that produce high-fidelity geometry requiring optimization. By invoking these methods within your script, the optimization process is integrated into the asset creation pipeline.

1. Reference the source Mesh you wish to optimize.
2. Define the reduction thresholds and parameters for the MeshLodUtility logic.
3. Call the GenerateMeshLods method to return an array of simplified Mesh objects.
4. Attach a LODGroup component to the GameObject containing your script results.
5. Map the generated Mesh objects to the appropriate LOD levels in the LODGroup array.

Additional Tips:

• Use AssetDatabase.AddObjectToAsset to parent the new MeshLodUtility outputs to the original mesh file to keep the Project window organized.
• High vertex counts may increase generation time; ensure the source Mesh is marked as readable in the import settings or memory before processing.
• The MeshLodUtility creates brand new Mesh instances that must be manually destroyed if not saved to the AssetDatabase to prevent memory leaks.
