Editor OverviewEdit

Editor panelsEdit

The editor workflow is split into five sections:

  • Geometry - Creating the 3D space using cube segments;
  • Texturing - Applying textures to geometry;
  • Entities - Adding interactive elements which can affect gameplay and powerups - this includes Props and Lights;
  • Decals - Detailing spaces with 3D models and light objects for extra geometry and decoration;
  • Global Data - Adjusting data which affect the overall rendering of the map within the game, such as terrain deformation type.

Exported mapsEdit

The exported maps will also contain a .cm or .sp file, according to the gametype the map was exported as.

These maps should be installed to C:\ProgramData\Revival\Overload on a Windows machine, and /usr/share/Revival/Overload on a Linux/OSX machine.

More information on these can be found below:

  • Mission Data ([levelname].mission)
    • Contains information such as the music to play, starting weapons, mission name, additional levels, etc;
  • Story text ([levelname]_)EN.txt)
    • Contains information which the game uses to display as comms, briefing, etc;
  • CM (Challenge Mode) Data (challenge_mode_[levelname].txt)
    • Contains information which the game will use to spawn operators within the map;

Guides & ResourcesEdit

There are numerous guides and resources available for the editor, including the documentation file which is shipped with the editor (found in the same folder as the EXE, titled 'Overload_Level_Editor_Documentation).

For tools that can be used to make editing tasks easier, see Level Editing Tools.

Operator & door reference guides (by LusTucc)Edit

These two images show the names of the operators and doors within the editor alongside their corresponding in-game model.

Decal Functionality (by Hattieboss)Edit

Hattieboss has created a spreadsheet which details the working status of decals within the editor. Also included are a list of the names displayed by certain decals' emissive textures; and links to download the editor/mission maps used to test the decals.

The document can be viewed here.

Texture Previews (by Fisholith)Edit

The textures shown in the editor are previews of the actual in game textures/materials.

This is an in-game reference for all of the textures.

The textures are laid out in rows of 6, exactly as you see them in the editor's "Texture List" when the View option is set to "SMALL". (See top left corner of Texture List.)

Tutorial Video (by Revival)Edit

An official YouTube playlist of level editor tutorials can be found here. The videos walk through geometry editing, creating a standard level layout, placing entities, decals, texturing, and more.
