HY Motion

HY Motion is a web-based platform that converts natural language text into high-fidelity 3D character animations, built on Tencent's open-source Diffusion Transformer model.

What is HY Motion?

HY Motion is an online tool by Tencent that transforms text descriptions into professional-grade 3D character animations. It uses a billion-parameter Diffusion Transformer (DiT) architecture with flow matching to generate realistic motions from natural language prompts. The platform runs in the browser and is free to start.

Key Features

• Billion-Parameter DiT Architecture — Leverages Tencent's open-source model with flow matching for high-fidelity motion generation.
• 200+ Motion Categories — Covers walking, running, dancing, fighting, and more across six major classes.
• Real-Time Generation — Animations are produced in seconds, enabling rapid iteration.
• Multiple Export Formats — Supports integration with Unity, Unreal Engine, Blender, Maya, and other 3D pipelines.
• API Access — Allows automated text-to-motion generation for enterprise workflows.
• Full-Stage Training Strategy — Employs Pre-training → SFT → RL loop for optimal physical plausibility and semantic accuracy.
• Trusted by over 10,000 creators — Used by game developers, animators, and VR studios worldwide.

Who Is It For?

• Game developers — Quickly generate character animations for prototypes or production without manual keyframing.
• 3D animators — Speed up workflow by using text prompts to generate base motions that can be refined.
• VR content creators — Create realistic avatar movements for immersive experiences.
• Indie game studios — Produce motion-capture-quality animations without expensive equipment.
• Digital content producers — Generate 3D animations for social media or marketing materials.

What Can You Do With HY Motion?

• Indie game studios: Create hundreds of character animations for games using simple text descriptions, bypassing the need for motion capture.
• VR content creators: Generate natural avatar animations for virtual reality applications with realistic movements.
• Animation directors: Produce complex motion sequences that would take weeks to keyframe manually, with precise instruction-following.

How Does HY Motion Work?

1. Enter a text description — Type a natural language prompt like "a person dancing" or "character waving hello".
2. Generate — The model processes the text and produces a 3D animation in seconds.
3. Preview — View the animation from multiple angles to ensure it matches your vision.
4. Download — Export the motion in industry-standard formats for use in your pipeline.

Pricing

HY Motion operates on a freemium model. Free tier allows limited generations; paid plans available for higher usage.
