Crumple Response

Crumple Response puts BeamNG.drive's soft-body crash physics into Flashing Lights.

You play Flashing Lights as normal. BeamNG.drive runs alongside it, and every time your vehicle hits something, your own copy of BeamNG.drive replays the crash on a matching BeamNG vehicle. Your Flashing Lights vehicle then crumples the way the BeamNG one did: bonnets fold, bumpers cave in, doors buckle.

What you get

• Real crash damage on your vehicle. SUVs crash as the Gavril Roamer, patrol sedans as the Grand Marshal, pickups as the D-Series, ambulances as the H-Series and fire engines as the MD-Series. The dent lands where you hit, scales with your speed, and keeps building up until you repair.
• It drives like it's damaged. A crushed front end costs engine power and top speed, and a bent front corner pulls the steering to one side.
• Accident scenes (experimental). Pre-wrecked cars that Flashing Lights builds for callouts are crashed by BeamNG.drive first (head-on, rear-end, T-bone, into a wall or under a truck).
• Co-op (experimental). Up to 10 players in Flashing Lights' online mode. Join your friend's server from the game's own server list. Each player's BeamNG.drive simulates their own vehicle, and the dents are shared with everyone in the server.

How it works Press Play and Melty starts both games. BeamNG.drive loads its small grid test map in the background. Nothing from either game is copied; the vehicles and physics come from your own BeamNG.drive.

Dents appear a second or two after a hit, while BeamNG.drive plays the crash out. Hold F7 in Flashing Lights to see the link status, and press F9 to crash-test the nearest vehicle.

Needs: Flashing Lights and BeamNG.drive on the same PC, and a PC that can run both at once. The first start takes an extra minute or two while BepInEx sets itself up.
