To generate smooth normals, set the smooth group to a value greater than or equal to ``0`` using :ref:`set_smooth_group<class_SurfaceTool_method_set_smooth_group>` or leave the smooth group at the default of ``0``. To generate flat normals, set the smooth group to ``-1`` using :ref:`set_smooth_group<class_SurfaceTool_method_set_smooth_group>` prior to adding vertices.

void **set_smooth_group** **(** :ref:`int<class_int>` index **)**
Specifies whether the current vertex (if using only vertex arrays) or current index (if also using index arrays) should use smooth normals for normal calculation.
Specifies the smooth group to use for the *next* vertex. If this is never called, all vertices will have the default smooth group of ``0`` and will be smoothed with adjacent vertices of the same group. To produce a mesh with flat normals, set the smooth group to ``-1``.
