BMW M6 Gran Coupe

Four mods, one car

• M6 Gran Coupe (v0.3.1) — the vanilla-first cosmetic baseline. A grey-box drivable that proved the vehicle pipeline end to end: Unity asset bundle, entity class, physics, and a live-world drive.
• San Marino Blue Performance Plus (v0.20.1) — the flagship chassis. Retuned steering, suspension, and drivetrain; custom engine audio driven by a small Harmony patch so the sound follows the load.
• Vanilla Red Performance Plus (v0.1.0) — the same chassis in the game’s own red.
• Native Paint System (v1.0.0) — four paint-ready finish masters and ten custom Warlock dyes, using the game’s dye system instead of shipping one bundle per colour.

What was learned

The vehicle pipeline is where most of the lab’s hard lessons about proof came from. A build can pass every automated gate and still ship the wrong body if the swap writes over its own source. Reference photographs have to be measured every pass, not only when something looks off. Those lessons now sit in the Geometry Lab standard and apply to every vehicle since.
