| * **"auto"** — The processor chooses flat vs smooth per-edge based on face dihedral (angle between adjacent normal vectors). Recommended default for general models. | * **"auto"** — The processor chooses flat vs smooth per-edge based on face dihedral (angle between adjacent normal vectors). Recommended default for general models. |
| * **"flat"** — Compute flat normals per face (no smoothing). Use for faceted, mechanical or intentionally sharp geometry. This is the default parameter because it always produces a mathematically correct mesh. | * **"flat"** — Compute flat normals per face (no smoothing).
