Yes, Hunyuan Motion is also known as HY-Motion 1.0, the open-source text-to-3D human motion generation model developed by Tencent's Hunyuan 3D Digital Human Team. Both names refer to the 1-billion parameter Diffusion Transformer model designed to generate SMPL-compatible skeletal animation data from natural language prompts. ### What types of motion does Hunyuan Motion generate best? Hunyuan Motion excels at generating solo human locomotion, athletic actions, martial arts routines, and dance choreography with realistic weight transfer and joint constraints. It generates single-person 3D skeletal animations formatted as FBX files ready for retargeting onto custom character rigs in external 3D suites. ### How should I structure prompts for optimal motion quality? Focus purely on describing concrete physical actions, joint movements, and sequential steps in under 60 words. Avoid describing character appearance, clothing, lighting, or camera angles, as the model generates raw 3D skeleton frames rather than rendered visuals. For multi-step sequences, describe actions in chronological order. ### What are the primary limitations of Hunyuan Motion? Hunyuan Motion is limited to single humanoid characters mapped to standard SMPL and SMPLH skeletons and cannot generate quadrupeds, creatures, or multi-person interactions like wrestling or partner dancing. It also lacks collision awareness for fine-grained finger-level object manipulation such as playing instruments or handling small tools. ### What file format does the model output, and how do I use it in 3D software? The model outputs standard 3D skeletal animation data in FBX format adhering to the SMPL and SMPLH joint hierarchy. You can import the exported FBX file directly into 3D DCC software like Blender, Autodesk Maya, or Unreal Engine to retarget the motion onto custom character meshes or drive pose-guided AI video workflows. ## Try Hunyuan Motion on Fuser Turn natural language motion descriptions into biologically plausible 3D skeletal animations and FBX capture files in seconds [Generate 3D motion](https://app.fuser.studio) ## Related models - [Meshy](https://fuser.studio/models/meshy.md) - [Rodin](https://fuser.studio/models/rodin.md) - [Tripo 3D](https://fuser.studio/models/tripo-3d.md) - [Hunyuan3D V3](https://fuser.studio/models/hunyuan3d-v3.md) - [SAM 3D Objects](https://fuser.studio/models/sam-3d-objects.md) - [Trellis 2](https://fuser.studio/models/trellis-2.md) Node reference: [Hunyuan Motion docs](https://docs.fuser.studio/docs/nodes/mesh/hunyuan-motion.md)
