Tencent Open-Sources Hunyuan3D World Model 1.0
At the 2025 WAIC (World Artificial Intelligence Conference), Tencent officially launched Hunyuan3D World Model 1.0, a powerful open-source AI model.
It is designed to generate interactive 3D worlds from just text or image inputs.
Key Capabilities:
Text‑to‑World and Image‑to‑World: Generate entire virtual scenes from textual descriptions or a single image.
Panoramic Proxy Pipeline: Uses a diffusion-based Panorama-DiT model to generate seamless 360° panoramas, then applies semantic decomposition and layer-wise depth mapping for accurate world reconstruction.
Interactive & Exportable 3D Meshes: Foreground elements are isolated for manipulation—objects can be moved, rotated, or scaled separately. Mesh export tools support integration into VR, simulation, gaming, and animation workflows.
Open-Source Release: Source code, pretrained weights, and technical documentation are publicly available via GitHub and Hugging Face, facilitating future adoption by developers and researchers globally
How It Works
Panorama-to-3D Pipeline: Uses a Panorama-DiT diffusion model to create immersive spherical scenes.
Scene Understanding: Semantically separates foreground and background for accurate reconstruction.
3D Mesh Export: Generated scenes are exportable into Unity, Unreal Engine, or Blender, allowing for integration into games or simulations.
Applications & How to Use
Tencent’s Hunyuan3D World Model 1.0 has practical applications across multiple industries.
Developers can rapidly prototype VR and simulation environments, generate scene assets for games and films, and create immersive spaces for architectural visualization or interactive storytelling.
Getting started is simple: clone the open-source repository (Tencent-Hunyuan/HunyuanWorld-1.0), follow the setup instructions (Python and PyTorch-based), and use demo scripts to experiment with text-to-world or image-to-world generation.
The model also includes a built-in 3D Model Viewer, allowing you to preview results directly in your browser.
