In the beginning was the red builder brush. It looked around itself and found it was alone. Alone in a great patch of matter which dimensions could not be known.

The Active Brush is the basic tool of UnrealEd. It is displayed as a wireframe of dotted red lines, and hence is is commonly referred to as the Red Builder Brush, or RBB. There is only ever one RBB in a map. It is a grind with which you'll be able to subtract or add matter from the Unreal World and thus create Unreal Geometry.

The RBB is like a cookie cutter, or a template. Make it into a shape, and then use that shape to create a new additive or subtractive brush that will alter the map's space. The basic procedure is this:

  1. Click on a Brushbuilder button in the toolbox: the red builder brush is forged into a new shape.
  2. Position it in the map (mouse control explains how to do this).
  3. Click on one of the brush operations in the toolbox – usually Add or Subtract.
  4. A new world brush is placed in the map, with the exact position and configuration of the RBB.
    • You can move the RBB to a new spot and add another brush of this shape.
    • You can re-make the RBB into a new shape.

Using the RBB[edit]

Starting from scratch[edit]

The RBB can take on an entirely new shape:

Editing the shape[edit]

Once you have a shape, there are many ways to modify it. Note that most of these methods can also be used to alter the shape of world brushes.

Saving the shape[edit]


Scaling or rotation behaves oddly[edit]

The RBB remembers its scaling and rotation, even when you give it a completely new shape. If it does not appear to do what you want it to, do one of the following:

Can't see the RBB[edit]

You can toggle visibility of the RBB in any UnrealEd Viewport's Viewport Caption Context Menu, or by pressing B when that viewport is active.
