Entities are inherently dynamic and can be controlled either by the game logic or level scripts. Entities can be created in-editor from patches or brushes, while pre-defined entities can be added from the right-click context menu in the main editor window. Lights, monsters, items, doors - anything which must do something as opposed to just constituting map geometry - are all examples of entities. EntitiesĮntities are functional objects placed in a map (“actors” to the Unreal mappers). If a user attempts to create a concave brush through a CSG operation, the editor automatically fragments it to create a number of smaller convex brushes that combine to create the desired concave structure. An example would be the material player_clip which prevents the player from entering the designated volume. This is done by applying special volume materials (a.k.a. At the very least, the outer hull of a map must be made from brushes since by default, they belong to the only entity class (the worldspawn) capable of sealing the map from the void.Īside from visual geometry, brushes can also be used to define volumes within a map with unique properties. Brushesīrushes are convex solids that form the basic geometry of a map - floors, ceilings, walls, and basic internal solids (such as steps or beams) that do not require a model are produced with brushes. There is a Video Tutorial where you can get started.Īny map will contain a number of standard elements, which are discussed below. Make sure to use the version provided with the sourceport (in the “Tools” directory), as it has been modified specially to work with RBDoom3BFG. TrenchBroom - The popular level editor for the original Quake can also be used to make maps for RBDoom3BFG. We have a dedicated tutorial vailable to get you started ! Blender - The free and open-source 3D software can now be used to make level when using the RBDoom3BFG sourceport.DarkRadiant - GTKRadiant modification made for The Dark Mod (also works with vanilla Doom 3) with many fixes, usability improvements and new features.GTKRadiant - Open source, multi-platform editor.EditWorld - ET:QW map editor specific information.PreyEdit - Prey map editor specific information.QuakeEdit - Quake 4 map editor specific information.DoomEdit - Doom 3 map editor specific information.Map editor - Built-in Windows-only level editor.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.
