Pipeline Flow

1. Security Check - Sanitize input, check rate limits
2. Cache Check - Return cached result if available (60% quota savings)
3. FLUX Generation - Generate high-quality 2D reference image
4. Hunyuan3D Generation - Convert 2D to 3D model
5. Validation - Verify GLB file integrity
6. Blender Optimization - Optimize topology, generate LODs, add collision
7. Export - Game-ready GLB with Draco compression

Quality Presets

Preset	FLUX Steps	Hunyuan Steps	Texture Res	Time	Use Case
Fast	10	10	2K	~45s	Quick prototyping
Balanced	15	25	2K	~60s	General use
High	25	35	4K	~90s	Production assets
Ultra	30	50	4K	~120s	Hero assets

Output Format

• GLB with embedded PBR materials
• 3 LOD levels (100%, 50%, 25%)
• Collision mesh (simplified convex hull)
• Draco compression (60-70% size reduction)

Optimizations

• TF32 Acceleration - 20-30% faster on L4 GPU
• Memory-Efficient Pipeline - No OOM errors
• Smart Caching - 60% GPU quota savings
• Automatic Retry - Handles API failures gracefully
• Async Operations - Non-blocking GPU calls

Code Quality

• Modern Python - Async/await, type hints throughout
• Modular Design - Single responsibility per module
• Clean Architecture - Easy to test and maintain
• Production-Ready - Proper error handling, logging
• 61% Code Reduction - 2481 → 960 lines

Deployment
