Hunyuan3D 2.0 is an open-source 3D synthesis system that generates and manipulates high-resolution textured 3D assets from images. It produces bare 3D meshes from condition images using a flow-based diffusion transformer and provides multiple interfaces including a local API server, a Gradio web app, and a Blender add-on.
Project overview
It outperforms previous state-of-the-art open-source and closed-source models in geometry details, condition alignment, and texture quality while offering an openly available pipeline for generating high-resolution textured 3D assets.

Best for
Developers, creators, and researchers who need an open-source pipeline for generating high-resolution textured 3D assets from images and have adequate GPU resources.
Key capabilities
Generates bare 3D meshes from condition images using a flow-based diffusion transformer.
Launches a local API server to handle web requests for Image/Text to 3D generation and texturing existing meshes.
Provides a hostable Gradio web application for 3D generation.
Ships a Blender add-on allowing direct use of Hunyuan3D 2.0 within Blender via an API server connection.
Limitations and risks
Full shape and texture generation requires 16 GB of VRAM in total; 6 GB is needed for shape generation alone.
Texture generation requires compiling a custom rasterizer and differentiable renderer via setup.py.
Getting started
Setup involves medium difficulty, requiring a Python environment with dependencies installed via pip and downloading large pretrained model checkpoints. The path to first success is to install PyTorch via the official site, run pip install -r requirements.txt, and then run pip install -e .
