The HY 3D: 3D Parts Decomposition workflow is designed to simplify the process of segmenting a 3D model into its individual components. By leveraging the Hunyuan3D model, this workflow automatically analyzes and breaks down complex 3D assets into manageable parts, making it easier for designers and developers to edit, reuse, and enhance 3D models. The workflow begins with the Load3D node, which imports the 3D model in FBX format. It then utilizes the Tencent3DPartNode to perform the decomposition, identifying and separating the model's constituent parts. Finally, the SaveGLB node allows users to export the decomposed model as a GLB file, ready for further use or modification. This process is particularly useful for game developers, 3D artists, and engineers who need to work with detailed models without manually segmenting them. The workflow's efficiency and precision in handling 3D assets make it a valuable tool in the digital content creation pipeline.
