How to optimize 3d models for unity games

https://assetstore.unity.com/packages/slug/373210 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 ━━━━━━━━━━━━━━━━━━━━━━━ INCLUDED TOOLS ━━━━━━━━━━━━━━━━━━━━━━━ 1. One-Click Mesh Optimizer — Reduce Tris & Vertices Reduce polygon count while preserving visual quality using industry-standard Quadric Error Metric (QEM) simplification for clean topology. Features: • High-quality polygon reduction • Vertex welding • UV seam & Bone weight preservation • Protection zones (keep important details intact) • Live preview system • Large mesh support (100k+ triangles) • Mesh export options • 100% Non-destructive workflow ━━━━━━━━━━━━━━━━━━━━━━━ 2. MeshWeld Pro — Mesh Combiner & Texture Atlas Combine multiple meshes and materials into optimized, atlased geometry. Reduce draw calls instantly without breaking your scene hierarchy. Features: • Static + Skinned Mesh support • Texture atlas baking & Material merging • BlendShape preservation • Shader auto-detection • Live performance stats (see FPS/Draw Call savings instantly) • Auto-configuration system • Full Undo support & Runtime API • Hierarchy-safe combining ━━━━━━━━━━━━━━━━━━━━━━━ 3. One-Click LOD Suite — Batch LOD Generator Generate full LOD chains across your entire scene in seconds. Async processing keeps the Unity Editor completely smooth while per-mesh optimization ensures perfect quality-to-performance trade-offs. 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
