# T3D File

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...
- export one brush:
- export a part of a map: either save, delete discards and export as above, or select, copy, paste into a text editor and save as a T3D file

### 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...)

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
    Begin Actor Class=LevelInfo Name=LevelInfo0
        TimeSeconds=17.008888
        Summary=LevelSummary'Entry.LevelSummary'

        AIProfile(3)=42
        AIProfile(4)=40
        AIProfile(5)=44
        AIProfile(6)=45
        AIProfile(7)=21846171
        AvgAITime=0.000000

    End Actor
    Begin Actor Class=Brush Name=Brush0

        PostScale=(Scale=(X=0.250000,Y=8.000000,Z=3.000000),SheerAxis=SHEER_ZX)
        TempScale=(Scale=(X=0.250000,Y=8.000000,Z=3.000000),SheerAxis=SHEER_ZX)

## T3D Utilities

- MapScale scales an entire .t3d file
- MeshMaker converts a prefab in .t3d format to a decoration
- [UnrealROC] converters: from 3DMF, to VRML/X3D/OBJ (including textures et al).

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.
