☯️ Tencent Hunyuan3D-2.1 Architecture Breakdown

📐 1. Hunyuan3D-Shape-v2.1 (3.3B)

Employs a 3.3-Billion parameter Flow Matching Diffusion Transformer (DiT) to reconstruct continuous signed distance fields (SDF) and marching cubes meshes with high topological accuracy.

🎨 2. Hunyuan3D-Paint-v2.1 (2.0B)

A 2-Billion parameter multi-view texture generator that replaces legacy flat RGB diffuse mapping with Physically-Based Rendering (PBR) channels, simulating metallic sheen, roughness, and surface normals.

⚡ 3. Production Readiness

Zero-cost community deployment ready on Hugging Face Spaces. Exports standard glTF/GLB files fully compatible with Unreal Engine 5, Blender, Unity, and Apple RealityKit.
