# Dynamic Subdiv

A system to display preview subdivisions on a model. Activate Dynamic Subdiv toggle to display assigned **FlatSubdiv** and **SmoothSubdiv** subdivision levels.

> **Note:** Dynamic Subdiv Preview do not apply subdivisions, resulting in no active points count change of the model when preview is active.

> **Note:** Example demonstrates Dynamic Subdiv active with SmoothSubdiv slider increased to simulate a smooth preview of the model.

#### Apply

Dynamic Subdiv settings can be applied as **Subdivisions** resulting in active points count increase.

> **Note:** **Dynamic Subdiv** toggle must be active to access the Apply button.

#### FlatSubdiv

Applies preview subdivision levels while retaining hard edges.

> **Important:** **FlatSubdiv** does not utilize **CreaseLvl** settings.

> **Tip:** Use in combination with **Smooth Subdiv** slider to achieve combined results.

#### Smooth Subdiv

Each level applies a smoothed subdivision, softening all edges of the model based on topology and assigned Creases.

> **Note:** With creased edges applied to the model, **SmoothSubdiv** level must be set higher than the assigned **Crease > CreaseLvl** to smooth creased edges.

> **Note:** ZBrush for iPad Dynamic Subdivs and Creases works the same in ZBrush desktop. Learn more in the provided external ZBrush documentation sections:\
