The world of 3D generative AI continues to evolve at a rapid pace, and Hunyuan3D is at the forefront of this revolution. Developed by Tencent, this open-source, high-quality 3D generative model has just received a major upgrade with Version 2.5, introducing powerful new features that make 3D modeling, animation, and texturing more accessible than ever before.
What’s New in Hunyuan3D Version 2.5?
1. Single-Image to Animated Characters
One of the most exciting updates is the ability to generate fully animated 3D characters from just a single image. Whether it’s a T-pose or A-pose reference, Hunyuan3D intelligently approximates the backside of the model — something that previous versions struggled with.
- Better Backside Approximation: Unlike Version 2.0, which had issues with reconstructing the back of characters, Version 2.5 delivers more accurate results.
- Automatic Rigging & Animation: The new version includes Mixamo-compatible bone binding, allowing users to apply pre-built animations (walk, run, jump, dance, etc.) directly to their models.
2. AI-Powered Mesh Reduction & Sketch-to-3D
- Surface Reduction AI: Simplifies high-poly models while preserving details.
- Sketch-to-3D Tool: Upload a hand-drawn sketch, add a text prompt, and Hunyuan3D generates a fully textured 3D model based on your input.
3. Improved Daily Usage Limits
- Version 2.0 had strict limits — users could only generate 2-3 models before hitting GPU quotas.
- Version 2.5 increases this to 20+ models per day, making it far more practical for artists and developers.
How to Use Hunyuan3D 2.5
Step 1: Access the Platform
Visit 3D.hunion.tencent.com and log in (supports WeChat, QQ, or email).
Step 2: Generate 3D Models
- Text-to-3D: Enter a prompt (e.g., “robot warrior”) and select a style.
- Image-to-3D: Upload a single image (or multiple views for better accuracy).
- Sketch-to-3D: Draw a sketch, describe it, and let AI generate a 3D model.
Step 3: Rig & Animate
- For humanoid models, use the automatic bone binding feature to apply animations.
- Supports Mixamo rigs, making it easy to import into Blender, Maya, or Unity.
- Download as FBX or GLB for further refinement.
Step 4: Refine & Export
- Use AI mesh reduction to optimize polycount.
- Generate PBR textures for realistic materials.
Workarounds & Tips
- If models fail to load, refresh the page or toggle settings.
- For better rigging, ensure characters are in T-pose or A-pose.
- Scale issues in Blender? Set import scale to 0.01 for correct proportions.
Final Thoughts
Hunyuan3D Version 2.5 is a massive leap forward in AI-assisted 3D modeling. With better topology handling, animation support, and higher daily limits, it’s becoming an indispensable tool for game developers, animators, and digital artists.
Best of all? It’s free and open-source!
