hi, in the unreal map editor, you construct a level with brushes. there are no vertices at all. what´s the key behind this idea? is it a good idea? thanks, gammastrahler

a brush is a simple set of geometry. for instance a staircase, a cube and so on.. instead of having a huge uncontrolled soup of polygons, you can group your polygons together to brushes and perform simple operations on it (like loading/saving, CSG,..)much better.
