The HY 3D: Smart Topology workflow is designed to streamline the process of optimizing 3D models by reducing their polygon count while maintaining essential details. This workflow is particularly useful for those working with high-poly models that need to be simplified for applications such as real-time rendering or efficient storage. It utilizes the Hunyuan3D model to intelligently reduce the complexity of a 3D model without compromising on quality. The process begins with the Load3D node, which allows users to upload their high-poly models in formats such as .glb or .obj. The core of the workflow is the TencentSmartTopologyNode, which applies advanced algorithms to achieve the desired level of topology optimization. Finally, the SaveGLB node outputs the optimized model in a format ready for further use or distribution.
