Maya 2012 Tutorial
How to Add Density to a Maya Polygon Object
Polygon mesh density can be added to individual faces or the entire object. If you are working with a polygon primitive object, you can access it's create node in the Channel Box or Attribute Editor and increase the mesh settings. To add density to specific faces, first select the faces, then use the Add Divisions feature.
Add a polygon plane to the workspace by choosing Create > Polygon Primitives > Plane (include options).
In the plane options set the Width, Height, Width Divisions and Height Divisions to 1. Click the Create button.
Select the plane and open the Channel Box. Click polyPlane1 in the Inputs section.
You can add move divisions by increasing the Height Divisions and Width Divisions to 4.
Right-click the plane and choose Face from the menu. Click one of the faces to select it.
Choose Edit Mesh > Add Divisions (include options) from the Polygons menu set.
Change Division Levels to 2 and click Add Divisions. The selected face now has 16 faces.
Another way to add density is Edge Loops. Choose Edit Mesh > Insert Edge Loop Tool from the Polygons menu set.
Click on one of the edges and an Edge Loop is added.
