Tencent Hunyuan's 3D Digital Human team has introduced HY-Motion 1.0, a billion-parameter text-to-3D motion generation model built on the Diffusion Transformer (DiT) architecture with Flow Matching. This model translates natural language prompts into 3D human motion clips using a unified SMPL-H skeleton, making it suitable for digital humans, game characters, and cinematics. The model is trained on a vast dataset of over 3,000 hours of motion data, including high-quality motion capture and animation assets, and is designed to improve instruction following and motion realism through reinforcement learning techniques. HY-Motion 1.0 is available on GitHub and Hugging Face, offering developers tools and interfaces for integration into various animation and game development pipelines. Why this matters: HY-Motion 1.0 represents a significant advancement in AI-driven 3D animation, enabling more realistic and diverse character motions from simple text prompts, which can enhance digital content creation across industries.
