PartMat: Material-Aware 3D Part Decomposition with a Single Global Latent

A new 3D decomposition pipeline aims to split objects by material boundaries instead of just functional parts. PartMat uses a single global latent to decode all parts in one pass, which could make editable asset generation cheaper and more practical for production workflows. The system also adds diffusion, reinforcement learning, and sparse-voxel post-processing to preserve detail.
