Hunyuan3D

What is Hunyuan3D?

Hunyuan3D is Tencent's free, open-source tool that turns a short prompt or a single image into a usable, PBR-ready 3D asset. It uses a two-stage workflow: a Diffusion Transformer to create coherent geometry, then a paint stage that bakes Albedo, Normal, Roughness and Metallic maps into seamless UVs. Models export with clean topology suitable for animation and integrate with Blender, Unity, and Unreal. The v2.5 weights (about 10B parameters) run locally on modest GPUs (around 6GB VRAM), and the project is released under Apache 2.0 with no subscription required. Outputs prioritize production-ready quality and multi-view consistency to avoid common 'Janus' artifacts.
