The 'HY 3D: Smart Topology' workflow is designed to streamline the process of optimizing high-poly 3D models by reducing their polygon count while maintaining essential structural details. This is particularly useful for applications where computational efficiency and rendering speed are critical, such as in gaming and virtual reality. The workflow leverages the Hunyuan3D model, known for its robust capabilities in handling complex geometries. It begins with the Load3D node, which allows users to upload their high-poly 3D models in formats like .glb or .obj. The core of the workflow is the TencentSmartTopologyNode, which intelligently reduces the polygon count based on a user-defined reduction level, ensuring that the model's visual fidelity is preserved as much as possible. Finally, the SaveGLB node outputs the optimized model, ready for use in various applications.
