Creases retain sharp edges when a model is smoothed with subdivisions or dynamic subdivisions.
Creases don't add edge loops to the model, resulting in no active point count change when applied.
CreaseLvl defines how subdivision level creases smooth when you apply subdivisions or dynamic smooth subdivisions.
CreaseLvl = 3
Dynamic SmoothSubdiv slider must be set to 4 or higher to smooth creased edges.
Subdivision level 4 or higher to smooth creased edges.
PG – Polygroups

ZBrush for iPad creases works the same as in ZBrush desktop. Learn more in our external ZBrush Crease Unmasked/Masked documentation.
