Limitations

Known constraints and workarounds.

Use N-gons (Slow) can increase mesh generation time on complex cuts. Disable it for faster viewport feedback on high-poly scenes.
The Baguette cut uses quad-only topology — the N-gon option has no effect on this cut.
Rose cut has no pavilion — pavilion-related parameters and the Z− gizmo are hidden for this cut type.
Changing Cut Type applies Set Good Proportions once, which resets crown, pavilion, and size values.
Gemgen Lite only includes the Round cut. The other 9 cuts require the Full edition.
