The T3D file format or Unreal Text File holds a text list of Unreal map objects. An entire map can be saved as this file format, or just a single actor or brush.

Note that while brushes, their applied textures and light actors are saved, the Unreal Geometry itself is not saved: upon importing a T3D file the map must be built.

Copying objects from UnrealEd and pasting into a text editor produces the same format.

Unreal Text format

Exported brushes and (other) actors. See T3D file.

  • Created by:
    • UnrealEd's File -> Import command
    • UnrealEd's Brush -> Import command (see Data Import and Export for more on both these commands).
    • is this created by external stuff too?

Exporting T3D

  • Export the whole map
    • File -> Export... (UnrealEd 1,2,3)
    • File -> Export -> All.. (UnrealEd 4 - UT3)
  • Export selected actors: File-> Export-> Selected Only ... (UnrealEd 4 only - UT3)
  • Export one brush: Brush -> Export ...
  • Copy/Paste: can copy paste any actor from any UnrealEd version to another one (Except for UnrealEd 4) or to any text editor such as notepad (Windows)

Importing T3D

File -> Import...

(note importing may take a LONG time)

Overheard on #utjb... :-)

<tarquin> t3d stores brushes & actors but not texturing, right?
<Mychaeel> Texturing as well.
(melds into the opening speech from Reservoir Dogs...)
<DaveA>Stores links to textures, and texture transforms, but not the pixels themselves

The T3D format is a text file which stores information about map actors. It's in fact identical to what can be copied from UnrealEd to a text editor. An exported map looks like this:


Begin Map

T3D File Structure

Ux,UT,UT200x Maps

Begin Map
    Begin Actor Class=<ClassName>
    ...
    End Actor
    Begin Actor Class=<ClassName>
    ...
    End Actor
    ...
End Map

UT3 Maps

Begin Map
   Begin Level NAME=PersistentLevel
      Begin Actor Class=<ClassName>
      ...
      End Actor
      Begin Actor Class=<ClassName>
      ...
      End Actor
      ...
   End Level
Begin Surface
End Surface
End Map

Note: as UT3 T3D files have different header, any other not-UT3 t3d file can't be imported into UT3 editor (UnrealEd 4)

T3D brush geometry

Information geometry is contained in the following actors:

  • Brush
  • Mover (only UT and U1 game)

For more information about T3D brushes, see T3D Brush.

Kefik: There can be also a tag 'CsgOper' which have one of two values ... 'CSG_Subtract' -> subtract the brush from space or 'CSG_Add' -> add this brush to shape.

Sobiwan: New to WIKI editing, but not using it. I was searching for the actual format of T3D and found Mongo's description of Planetunreal to be extremely helpful. I'll ask him (mongo@planetunreal.com) if we can use and/or edit his description here. The format is much more involved than described here. We can even supply examples of how to do particular hacks.

MadNad: Interestingly, I was able to convert a Quake3_Level into a unreal map. Quite interesting. First i converted a *.bsp to a *.map in quake, then I made a level that was just a huge cube and converted it to *.t3d. With an external app (i'll have to find the name of it ) I was able to merge these two together. After some scaling and switching additive brushes in quake to subtractive brushes in ued and subtractive to additive, I compiled and had q3dm7 geometry. I don't necessarily recommend doing this, as it will take more time to fix than create it from scratch, but I thought I would share a little experience I had with this. --SeriousBarbie (talk) 21:11, 11 August 2016 (EDT)
