Time for action – using BSP brushes and static meshes

The Red Builder Brush creates BSP brushes. It also acts as a template for creating BSP Geometry and does not show up in the game.

In the previous screenshot you can see that the red builder brush has taken the form of a square template for creating BSP geometry. You can create different sizes and types of BSP.

Hammer source engine still uses BSP operation to construct the main shell of the level, but the majority of next-gen engines heavily rely on static meshes. Static meshes is what you will be using to primarily define how your map looks in UDK. Static meshes are the models that make up the 90 percent of your level. Creating static meshes requires you to have a 3D application, such as XSI, Maya or 3Ds Max, and so on.

• Red builder brush is what you will use to create BSP brushes

• Static meshes is what you'll be using to detail the environment
