Read the tracks

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

Step 2 reads a circuit the way EVO does and writes everything it is made of under work/evo, in EVO's own terms: the track, its layouts, objects, instances, lights, decals, splines, start positions and more, with the meshes, materials and textures they use.

Point to the game's executable

EVO describes the layout of its data inside AssettoCorsaEVO.exe, so step 2 needs it. Pass it with --exe, or set EVO_EXE once:

export EVO_EXE="/path/to/Assetto Corsa EVO/AssettoCorsaEVO.exe"

$env:EVO_EXE = "C:\path\to\Assetto Corsa EVO\AssettoCorsaEVO.exe"

The examples below assume EVO_EXE is set.

List the circuits

GAME is the folder you extracted, or content.kspkg itself: the result is the same.

Terminal

beamng-assetto evo tracks game/

Output

brands_hatch    Brands Hatch: GP (9 modes), Indy (4 modes)
spa             Circuit de Spa Francorchamps: GP (3 modes)
cota            Circuit Of The Americas: Club (3 modes), GP (3 modes), National (3 modes)
donington       Donington Park: GP (3 modes), National (3 modes)
laguna_seca     Laguna Seca: GP (9 modes)
nurburgring     Nurburgring: 24h (3 modes), Gp Strecke (3 modes), Mullenbachschleife (1 mode), …
…

The first column is the circuit's key, used by every other command.

Export circuits

beamng-assetto evo export game/ laguna_seca

beamng-assetto evo export game/ spa monza suzuka

beamng-assetto evo export game/ all

The export uses every CPU core; -j sets the number of worker processes. A circuit's own files are small (Laguna Seca: 9 MB); the assets they use are written once for all circuits, about 17 GB for the whole game.

Run an export again and it only rewrites the assets that changed, when it reads from an extracted folder. Straight from content.kspkg, a game update rewrites them all. --force writes everything again.

Check what an export holds

Terminal

beamng-assetto evo info laguna_seca

Output

Export only some parts

-p/--part exports only the parts you name; the assets follow what those parts use. It is mostly useful when you work on the tool itself.

Terminal

beamng-assetto evo export game/ laguna_seca -p layouts -p starts

The parts are baking, cameras, containers, decals, instances, layouts, lights, marshals, objects, particles, sound, splines, starts, surfaces, track and zones.

Extract the game

Step 1. Look inside content.kspkg and extract it into a folder, once, then only what changes.

Build the levels

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