Hunyuan3D-2.1 is Tencent's breakthrough 3D asset generation system that turns single images into production-ready 3D models with physically-based rendering (PBR) materials. Building on the strong foundation of Hunyuan3D 2.0, this latest Hunyuan3D-2.1 version delivers significantly improved texture quality with finer surface details and enhanced three-dimensional depth perception.
While Hunyuan3D 2.0 already impressed with solid geometry generation, Hunyuan3D-2.1 takes it to the next level with more nuanced material textures and better spatial understanding. The Hunyuan3D-2.1 system creates proper PBR materials with separate albedo, metallic, and roughness maps, making your generated objects respond to lighting realistically - metals shine convincingly, fabrics absorb light naturally, and surfaces have that perfect tactile quality.
For those familiar with the previous version, you can check out the to see how far Hunyuan3D-2.1 has come.

: 3.0 (texture alignment strength)Image Preparation is Everything: Clean backgrounds and clear subjects are absolutely critical for optimal Hunyuan3D-2.1 performance. The model performs dramatically better with well-prepared input images - remove backgrounds, center your subject, and ensure good lighting on the main object.
Mesh Quality Control: The Post Process Trimesh
node is your friend in Hunyuan3D-2.1. Enable remove_floaters
and reduce_faces
for cleaner results. Adjust max_facenum
based on your needs - lower for real-time applications, higher for high-quality renders.
Texture Resolution Balance: The octree_resolution
in the VAE Decoder controls mesh detail level in Hunyuan3D-2.1. 256 is the default, but you can push it higher for more geometric detail if you have the compute power.
Research & Development:
This workflow is powered by Hunyuan3D-2.1, developed by the Tencent Hunyuan3D Team. The Hunyuan3D-2.1 ComfyUI implementation is created by visualbruno and the open-source community, bringing cutting-edge Hunyuan3D-2.1 technology to creators worldwide. Special thanks to the research team for making this fully open-source - democratizing access to production-quality 3D asset generation through Hunyuan3D-2.1.
