Overview

HY Motion is an online platform that generates high-fidelity 3D character animations from natural language text descriptions. It is powered by Tencent's open-source HY Motion model, built on a billion-parameter Diffusion Transformer (DiT) architecture. The platform is designed for game developers, 3D animators, indie studios, and content creators who need professional-grade motion assets quickly.

How it works

HY Motion uses a billion-parameter Diffusion Transformer with flow matching technology to convert text prompts into 3D animations. The model employs a full-stage training strategy, including pre-training, supervised fine-tuning (SFT), and reinforcement learning (RL), to optimize physical plausibility and semantic accuracy. Users type a description like 'a person dancing' or 'character waving hello', and the system generates the animation in seconds.

Key capabilities

The platform covers over 200 motion categories across 6 major classes, including walking, running, dancing, and fighting. It offers real-time generation, high-fidelity output, and exceptional instruction following for complex motion sequences. The model's billion-parameter architecture ensures fluid and natural animations that meet professional standards for games and films.

Who it is for

HY Motion is designed for game developers, 3D animators, indie game studios, VR content creators, and digital content producers. It is also suitable for enterprises that need automated text-to-3D motion generation at scale through its API. The platform is trusted by over 10,000 creators worldwide.
