The leap from a high-poly sculpt to a game-ready asset has just become a matter of seconds. With the implementation of Hunyuan Polygen 1.5 on Scenario, creators now have access to Tencent’s state-of-the-art retopology model designed to transform complex 3D meshes into optimized, production-grade geometry.
A New Era of Mesh Optimization
Unlike traditional math-based decimation tools, Hunyuan Polygen 1.5 utilizes an autoregressive mesh generation approach. This allows the AI to "understand" the flow of the object, directly learning quad topology end-to-end to produce cleaner continuous edge loops and superior wireframe quality.
🚀 Key Technical Breakthroughs
This model is built to handle the heavy lifting of the 3D pipeline while maintaining professional standards:
Native Quad Support: Specifically designed to generate high-quality quadrilateral faces, which are essential for smooth deformations in animation.
Industry-Ready Outputs: Designed for professional pipelines in game development, VR content creation, and high-end animation.
Massive Reduction Power: Effortlessly converts heavy meshes into efficient assets (e.g., transforming complex armor into ~8k vertices) without losing the original silhouette.
Technical Settings on Scenario
Scenario provides a streamlined interface to control the retopology outcome with precision:
Parameter | Options | Purpose |
Polygon Type | Quads / Triangles | Choose Quads for animation and subdivision workflows, or Triangles for raw engine performance. |
Face Level | High / Medium / Low | Adjusts the reduction intensity. Use Low for mobile assets and High for hero characters. |
Input Format | GLB / OBJ | Fully supports the industry's most common 3D file formats. |
Why Hunyuan Polygen 1.5 is a Game Changer
Traditional retopology is often a manual and time consuming bottleneck. Hunyuan Polygen 1.5 removes this barrier by automating the creation of clean edge flows. As a result, your assets are not only smaller in file size. They are also structurally smarter, ready for rigging, animation, and deployment in Unity or Unreal Engine with minimal cleanup effort.
Take Action: Optimize Your Workflow
Take Action: Streamline Your 3D Pipeline
Leave chaotic topology behind. From indie games to cinematic productions, Hunyuan Polygen 1.5 helps your assets stay efficient, flexible, and visually polished from start to finish.
Pro Workflow Tip
Block out your concept in Meshy, sharpen and define forms with UltraShape 1.0, then process the model through Hunyuan Polygen 1.5. The result is a clean, quad focused mesh that is optimized, animation ready, and engine friendly.
