How to optimize 3d models for unity games
https://assetstore.unity.com/packages...
Ultimate Mesh Optimization Suite — Mesh Reduction, LOD & Mesh Combiner
Complete Unity optimization pipeline for meshes, draw calls, and LOD generation — all in one professional toolkit.
Bloated meshes. High draw calls. Manual LOD work.
Optimize your entire project directly inside Unity using a connected workflow designed for performance-heavy scenes, characters, environments, VR, mobile games, and large-scale productions.
Reduce polygons → Generate LODs → Combine meshes → Improve performance.
No external software. No destructive workflows. No pipeline interruptions.
Includes 3 complete optimization systems in one package:
• Mesh Reduction
• Batch LOD Generation
• Mesh Combining + Texture Atlas

Features:
• Batch LOD generation for entire scenes
• Async background processing (no editor freezing)
• Per-mesh customization & optimization
• Static + Skinned Mesh support
• Up to 7 custom LOD levels
• Smart auto-grouping
• Scene visualization overlay
• Prefab-safe workflow & Full Undo support
• QEM-powered simplification
