/*text_start*/\C020202Inner Regroup\C484848 determines whether a new Polygroup color is assigned to the inner portion of the mesh when adding an edge loop. \C020202Outer Regroup\C484848 determines whether the added edge loop is assigned a new, separate Polygroup color.

\C020202Crisp\C484848 is used to help create sharper corners or folds in the mesh. When pressed, the added edge loop has minimal width. Later, when the mesh is subdivided and smoothing is performed, the extra polygons in this edge loop prevent smoothing from taking place along its edge.

Incidentally, the \C020202Crisp\C484848 technique enables you to define crisp edges in a way that's perfectly compatible with all other modeling programs. When the low-res cage is exported to another program and subdivided/smoothed (using the Catmull-Clark algorithm), these edges appear the same as in ZBrush.

An alternative to Crisp edges is the \C020202Crease\C484848 function, which allows you to 'tag' certain edges to be shielded from smoothing. This feature is proprietary to ZBrush, and performs its task without changing the mesh's polygon count (important for \C020202Morph Targets\C484848).

\C020202Displace Amount\C484848 determines by how much polygons are extruded when the edge loop is added.
