Hunyuan3D-MLX brings Hunyuan3D to Mac

This is the kind of port that matters more than the benchmark table suggests: it turns a CUDA-leaning open 3D pipeline into something Mac developers can actually run locally. The catch is that it is still an early, single-machine proof point rather than a polished cross-device release.

• –Hunyuan3D-Paint has been a pain point on Mac because of CUDA-specific dependencies, so replacing rasterization, sparse conv, BVH, and unwrap steps with Metal-friendly paths is real infrastructure work, not just packaging
• –The MLX speedup is the headline because texture generation is where Apple Silicon now looks meaningfully competitive instead of merely compatible
• –ComfyUI nodes plus published MLX weights lower the barrier for creators who want local 3D workflows without an Nvidia box
• –The repo itself still flags quality below CUDA and notes that full MLX shape support is unfinished, so this is promising but not yet the definitive Mac path for Hunyuan3D
• –More broadly, it reinforces a trend: Apple Silicon support for open generative tooling keeps improving when developers are willing to do backend-specific porting instead of waiting for upstreams
