New Map This will create a new empty space. You can start here a new map If you had an opened unsaved map, first save it. You may launch several sessions of UED, but you cannot open several maps in the same session

Open Map This will simply do what it says, open an existant map.

Save Map This simply saves your map

Undo Very obviously as the next button is, this one undo the last action

Redo Redo the last action


Search This option is very important, as you may search for placed items in of all types placed at any location in the map.
You may just use the first letter of the item in the namefield at right to constrain the search within this range.

  • Music Browser This will bring up the music browser, here you may load any music file from the UT music folder in UMX format. You may also import several formats like Wav, S3M, Mod, Stm, It, Xm, Far file and then export it as a UMX formatted music file. When selected you may listen to it, and when satisfied, you may add it in the Level Property in order to link it with the map.

  • Texture Browser Well, this is one option all mappers should know, how would you start your new map else. Here you can open and save texturepacks. You may import PCX and BMP.
  • More info here

  • Mesh Browser This will open the mesh viewer, not much you can do here, or just look for the right mesh to use if you messed with the mesh of some item. No load nor save, nor improt or export, just view and select to use.


    2Dshaper Here you can build your 2D shapes that you can use in your map. More about this Shaper is explained in other help files. You may export and import your shapes here as 2DS files.
  • how it works,
  • avoid tesselation

  • Script Editor This opens the Script Browser, very important if you intend to make your own items, like weapons, ammo, voicepacks, mutators and such.
  • how it works

  • Actor Properties This icon opens up the Actor properties for the selected item. All the properties and options for this actor can be set here. It would have the same effect as pressing F4.

    Texture Properties With this icon you open the surface properties of the selected surfaces(s) also called polygons, the actual surfaces have a texture, and it's the surfaces flags or options that are set and not the texture properties. Texture properties are set in the texture browser. Choose here all of the flags like translucence, masked, unlit, etc. The same option will show when pressing F5.


    Rebuild Geometry This icon let's you Rebuild geometry ONLY, this means that only the geometry from the visible brushes is rebuild; light will not be rebuild thus be ignored and deleted at tyhis time, showing you the map without any lighting, that is plain texturelook without any shadows or light casting. This is also a good state for testing the map, it will run faster without lighting.
  • Rebuild geometry is very important when you want to test your map and you just added some substracted brush, any player and bot will instantly die if you didn rebuild geometry, you may also rebuild all, this produce the same.

    Rebuild Light Rebuild lighting ONLY will, as it says, only rebuild the light. This is used when you put some additional lightsources and want to see the effects. I cannot say it enough that you have to rebuild the light each time you added lightsources, and intend to navigate in one of the 3D views, faling to do so will inevitably crash the engine, because of the added lightsources are in some temporary buffer to view it in 3D, the engine asks for a light rebuild. Remember this when you have a crash in 3D after adding lightsources.

    Rebuild Paths Rebuild Paths ONLY will do exactely this, nothing else. Don't expect bots to use the freshly added playerstarts and items and pathnodes when you test your map, without rebuilding paths.

    Rebuild Complete And now the most important icon, this on rebuilds all, this means that it rebuilds the geometry, the lighting and also the paths. But it also does much more. Some of the geometry will not be rebuild with rebuild geometry like the BSP optimisation that will also rebuild your zones here. More in the next option.

    Rebuild Options This icon opens the settings for the Rebuild All option. It let's you chose what to rebuild, if for example the path is already, you did not add any path or items and is perfect, you may uncheck it here. same for geometry.
    If you are new to this, don't touch the sliders as they are already put to maximum quality settings. Same goes for the checks on the BSP settings. If you are sure of what you understand her, feel free to play with it to get better results, or faster results, anyhow, any other setting will have other results obviously enough, that's what is expected and why you change settings.
  • "Only rebuild visible actors" in the geometry field allows you to rebuild only the actors that are visible at this time, you made this with the groups you selected, the groups that are unchecked and hidden will not be rebuild, have a look at my fast rebuild trick, and you will see what i mean by power user in UED. The same applies to the checkable option in the light section here.

    Run Test Level What to say here, test your map will launch your map and you will have the GodMode option available, obvious. This will be a simple DM.
