**Verdict:** at defaults `trellis_mac` wins on quality (crisper face + geometry, richer color); `hunyuan3d_mlx` is faster, ~3× lighter, and the only local 3D op that runs on M1. `sf3d` stays the ~5s draft tier. All free/offline; fal cloud for on-demand SOTA without the local wait.
### Phase D — hunyuan Studio tuning (2026-07-16, M3 Ultra) → new operator defaults
Raised the config from the laptop-tuned defaults to `octree_resolution 384` + `remesh_faces 120000` + `texture_size 4096`. **4096² bake works on the Studio GPU — no Metal command-buffer watchdog** (the existing `extract_textiles` tiling handles it; `uv_feature_map` never needed patching). Result: **380s** (shape 160 + tex 221), peak 20.2GB, 21.5MB GLB, 78k verts / **120k faces**, 4096² baseColor+MR. Quality jump is real — the melted face gains defined eyes + structure, tail geometry sharpens, textures crisper; closes most of the gap to trellis (trellis still edges the face). Cost: ~46% slower + ~3× file size vs the 40k/2048 default. **These are now the `hunyuan3d_mlx` operator defaults** (all still param-overridable; drop to `remesh_faces 40000`/`texture_size 2048` for fast drafts). 4096 on the M1 Ultra: verifying.

Defaults are fleet-safe on both Ultras.
