Here are the known editing tools that can be used for creating maps for id Tech 4 engine games. However, pure-additive geometry is simpler from the engine’s perspective (since the order of brush creation is no longer critical), and completely eliminates the “BSP holes” that plague Unreal levels.

Users of Unreal-based engines may initially find Doom 3 editing overly complex: instead of subtracting a simple room, it is necessary to create solid brushes for floor, ceiling and walls and make sure they do not leave any gaps.

This is contrasted with “subtractive” editing which is used in Unreal and its derivatives - in these games the world starts out solid and rooms are subtracted from it, with extra details such as pillars being added back. Mapping for id Tech 4 games is based on ‘additive’ editing, whereby the level designer adds solid geometry to an empty “world”, know as the void in Doom 3.
