# Subdividing a Model

The Subdivide feature is useful for creating precise highlights and spotlights. The polygons in the 3D model are subdivided at the time of render according to the value you specify, resulting in smoother rendered surfaces.

Spotlight on a polygon model rendered with Subdivide off. | Spotlight on a polygon model rendered with Subdivide set to 2.

To subdivide a model:

1. Select the model or geometry you want to subdivide.
2. In the Geometry menu, click Subdivide to enable the Subdivide field.
3. Edit the Subdivide value. The default value is 5.
   NoteThe smaller the value, the slower the rendering.
4. Click Process or Preview to see the subdivision effect.

You can animate the Subdivide channel in the Channel Editor; however, expect a longer rendering time when the Subdivide value changes over several keyframes.
