Build the levels

Step 3. Build one BeamNG mod per circuit, with a level per layout, and install it.

Step 3 reads only step 2's output and builds a BeamNG.drive mod for each circuit, holding one level per EVO layout.

See what you can build

Terminal

beamng-assetto beamng list

Output

laguna_seca  (Laguna Seca)
  GP                       evo_laguna_seca_gp  modes: GP Race, GP Time Attack, Hotstint
nurburgring  (Nurburgring)
  24h                      evo_nurburgring_24h  modes: 24h Hotstint, 24h Race, 24h Time Attack
  Gp Strecke               evo_nurburgring_gp_strecke  modes: Gp Strecke Hotstint, Gp Strecke Race, …
…

Each line under a circuit is a layout, the BeamNG level it becomes, and its EVO game modes.

Build and install

beamng-assetto beamng build laguna_seca --install

beamng-assetto beamng build nurburgring -l Nordschleife -l "Gp Strecke" --install

beamng-assetto beamng build all --install

The mods are built in work/beamng/evo_<circuit>/. -o/--out chooses another folder.
-l/--layout builds only the layouts you name (EVO's names, any letter case).
The build uses every CPU core; -j sets the number of worker processes. The Nürburgring's seven layouts take about seven minutes on a 16-thread desktop.

--install links each mod into BeamNG's mods/unpacked/ folder, so the levels show up in the game. You can also install later:

Terminal

beamng-assetto beamng install laguna_seca

The install finds BeamNG's user folder (…/BeamNG.drive/current) on its own: in %LOCALAPPDATA%\BeamNG\BeamNG.drive\current on Windows, in ~/.local/share/BeamNG/BeamNG.drive/current on Linux. Pass --user-folder if yours is elsewhere.

The install makes a symbolic link. On Windows that needs Developer Mode turned on, or a terminal run as administrator. You can also copy work/beamng/evo_<circuit> into mods/unpacked/ yourself.

Choose the time and the sun

A level starts at the time of EVO's race session, with the sun where it is at the circuit's coordinates. Change the date and time with --when, in local time:

Terminal

beamng-assetto beamng build laguna_seca --when "2026-06-20 19:30" --install

--location computes the sun for another place instead: latitude, longitude, and the civil UTC offset in hours.

Terminal

beamng-assetto beamng build laguna_seca --location 36.58 -121.75 -8 --install

Rebuild

Running a build again only rewrites what changed, so rebuilds are quick. --force writes every shape and texture again.

Don't rebuild a level while BeamNG has it loaded. Quit to the menu, or close BeamNG, first.

Read the build report

Every build ends with a report: the levels it wrote, what each part placed, and the problems it met. When BeamNG can't do exactly what EVO does, the build says so, with a count. Warnings are there to inform you. If a circuit has errors, the other circuits still build, and the command ends with a failure status. Add -v before the step (beamng-assetto -v beamng build …) for every detail.

What a mod holds

work/beamng/evo_<circuit>/                     the mod, one per circuit
  levels/evo_<circuit>_<layout>/                one level per layout
    info.json                                   title, description, place, spawn points, date
    preview.png                                 EVO's menu picture with its map of the layout
    art/terrains/                               the terrain and its materials
    forest/, art/forest/                        trees, crowds and props
    art/rubber/                                 the rubber on the racing line
    quickrace/<layout>.race.json                the quick race and time trial
    main/                                       the level's objects
  gameplay/missions/evo_<circuit>_<layout>/     the AI race
  art/evo_<circuit>/shapes/, textures/          shared by the circuit's levels

Read the tracks

Step 2. List EVO's circuits, export them part by part, and check what an export holds.

Drive in BeamNG

Find the levels in BeamNG.drive, choose where to start, and use the time trials, traffic and time of day.
