Introducing WaveSpeedAI Hunyuan3D V2.1 on WaveSpeedAI

Tencent Hunyuan3D 2.1 Arrives on WaveSpeedAI: Production-Ready 3D Asset Generation with PBR Materials

The future of 3D content creation has arrived. WaveSpeedAI is excited to announce the availability of Tencent Hunyuan3D v2.1, a groundbreaking image-to-3D generation system that transforms single images into high-fidelity, production-ready 3D assets complete with physically-based rendering (PBR) materials. This is the first fully open-source solution delivering true PBR-textured 3D asset generation at scale.

What is Hunyuan3D v2.1?

Hunyuan3D v2.1 represents a major leap forward in AI-powered 3D generation technology. Developed by Tencent’s Hunyuan team and released in June 2025, this scalable 3D asset creation system advances the state-of-the-art through two pivotal innovations: a fully open-source framework and a revolutionary PBR texture synthesis pipeline.

Unlike its predecessor that relied on basic RGB texture models, Hunyuan3D v2.1 leverages physics-grounded material simulation to generate textures with photorealistic light interactions. This means your 3D assets feature realistic metallic reflections, subsurface scattering, and material properties that behave correctly under any lighting condition.

The system has already gained significant enterprise adoption, with over 150 companies integrating the technology—including Unity China and leading 3D printing company Bambu Lab.

Key Features and Capabilities

Production-Ready PBR Materials

The upgraded PBR pipeline simultaneously generates albedo, metallic, roughness, and normal maps from multiple viewpoints. This captures micro-details like leather grain, brushed aluminum finishes, and fabric weaves with remarkable accuracy. Textures support resolutions up to 4K, delivering a qualitative leap in surface rendering quality.

Tenfold Improvement in Geometric Precision

Compared to version 2.0, Hunyuan3D v2.1 delivers a tenfold improvement in geometric precision. This translates to significantly more detailed and accurate 3D models, particularly for complex objects like characters, intricate machinery, and detailed environments.

3D-Aware Consistency

The system introduces 3D-Aware RoPE (Rotary Position Embedding) to inject spatial information, dramatically improving cross-view consistency. This enables seamless texturing without visible seams or artifacts between different viewing angles.

Industry-Standard Export Formats

Generated assets export to OBJ, FBX, GLB, and other standard 3D formats with embedded PBR maps. This makes Hunyuan3D assets drag-and-drop ready for game engines like Unity and Unreal Engine, as well as 3D software like Blender.

Watertight Mesh Generation

The Hunyuan3D-DiT architecture produces watertight meshes ready for downstream applications including 3D printing, animation rigging, and physics simulation.

Real-World Use Cases

Game Development

For game developers, Hunyuan3D v2.1 accelerates asset creation workflows dramatically. Convert concept sketches into fully-textured 3D models ready for integration into your game engine. The low-polygon stylization capabilities help manage face counts for performance optimization, while the PBR materials ensure your assets look stunning under dynamic lighting.

E-Commerce and Product Visualization

Create photorealistic 3D product models from existing product photography. The accurate material representation makes these assets perfect for interactive product configurators, AR try-on experiences, and 360-degree product views.

Film and Animation Production

Generate high-fidelity 3D assets for previsualization, background elements, or even final production use. The drivable 3D character animation functionality extends the model’s applications into animation production pipelines.

3D Printing and Manufacturing

Produce watertight meshes with proper topology for 3D printing workflows. Bambu Lab’s integration demonstrates the model’s effectiveness for consumer-grade 3D printing applications.

AR/VR Content Creation

Build immersive virtual environments faster than ever. The seamless Unity and Unreal Engine integration means generated assets work perfectly in VR applications with minimal post-processing.

Performance That Speaks for Itself

Hunyuan3D v2.1 has been rigorously benchmarked against leading commercial and open-source alternatives including Michelangelo, Craftsman 1.5, Trellis, TripoSG, Step1X-3D, and Direct3D-S2. The results confirm its superiority:

Best-in-class CLIP scores for condition-following ability
Superior CMMD and FID metrics for texture-photo consistency
Highest human preference ratings in comparative evaluations
Industry-leading geometric detail preservation

In direct comparisons with popular alternatives like Meshy, Hunyuan3D consistently outperforms on accurate recreation of curved and flat surfaces, with better seam quality and superior back-of-object extrapolation.
