tomevault-io Unity Scene Optimizer
Analyzes Unity scenes and provides performance optimization recommendations for rendering, physics, memory, and platform-specific concerns.
What This Skill Analyzes
1. Rendering Performance
Analyzes draw calls (target: <100 mobile, <2000 desktop), identifies batching opportunities, recommends material consolidation and static batching.
2. Texture Optimization
Reviews compression formats (BC7/ASTC), mipmap usage, texture atlasing, and platform-specific import settings.
3. GameObject Hierarchy
Targets: <500 GameObjects mobile, <2000 desktop. Identifies deep nesting, recommends object pooling and LOD groups.
4. Lighting and Shadows
Recommends baked lighting over realtime (1-2 lights mobile, 3-4 desktop), minimal shadow-casting lights.
5. Physics Optimization
Analyzes Rigidbody count, collider complexity, collision matrix configuration. Recommends simple colliders over Mesh colliders.
6. Mobile-Specific
Platform targets: 60 FPS iOS (iPhone 12+), 30-60 FPS Android. See mobile-checklist.md for complete requirements.
Optimization Workflow
- Measure: Frame Debugger, Stats, Profiler metrics
- Identify: GPU/CPU/Memory/Physics bottlenecks
- Apply: Quick wins (static batching, compression) → Medium (atlases, pooling, LOD) → Major (hierarchy refactor, culling)
- Validate: Compare before/after metrics
See optimization-workflow.md for detailed steps and timelines.
Platform-Specific Targets
| Platform | Draw Calls | Triangles | Texture Memory | Lights |
|---|---|---|---|---|
| Mobile Low | <50 | <20k | <100MB | 1 |
| Mobile Mid | <100 | <50k | <250MB | 1-2 |
| Mobile High | <150 | <100k | <500MB | 2-3 |
| PC Low | <500 | <200k | <1GB | 3-4 |
| PC Mid | <1000 | <500k | <2GB | 4-6 |
| PC High | <2000 | <1M | <4GB | 6-8 |
| Console | <1000 | <800k | <3GB | 4-6 |
