# Crease

Creases retain sharp edges when a model is smoothed with subdivisions or dynamic subdivisions.

Geometry > Crease options

> **Note:** Creases don't add edge loops to the model, resulting in no active point count change when applied.

> **Note:** **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.

#### Crease actions include:

**PG** – Polygroups

**UM** – Unmasked surfaces

> **Note:** ZBrush for iPad creases works the same as in ZBrush desktop. Learn more in our external ZBrush [Crease Unmasked/Masked](https://help.maxon.net/zbr/en-us/Default.htm#html/reference-guide/tool/polymesh/geometry/geometry.html) documentation.
