Brush

A brush is a convex block created with Hammer's Block tool. Unless tied to an entity it will form part of the backbone of the map, defining visibility as a world brush.

Brushes are complimented in Source with models:

• Models cannot control visibility but allow for greater detail (geometry and animation), greater consistency, and dynamic lighting.
• Brushes should not have too many faces, are each unique, and are lit exclusively with Lightmaps (which do not change once the map has been compiled).
