Skin pass (build_cars.py, whole procedural fleet rebuilt):
- warp_obj() kills the slab: plan taper (nose/tail pull in), tumblehome (the
glasshouse leans inward above the belt) and rocker tuck, applied to
world-space verts so det_ panels stay flush with the body.
- Beveled body edges catch light instead of vanishing into flat shading.
- Wheels are tyre + rim with the mesh centred on the hub and the OBJECT at the
hub -- the old wheels baked position into their verts, so a spinning wheel
would have orbited the car's origin. Chrome det_hub hubcaps on every corner,
dark arch shrouds so wheels sit in wells rather than under a slab.
- B-pillars over the one-piece glasshouse, licence plates, exhaust, door
handles. Mirrors anchored to where the tapered flank actually ends up.
Destruction feel:
- Visual wheels spin with road speed and the fronts steer (rotation order YXZ:
yaw then roll, so steered wheels roll about the steered axle).
- Shed panels burst outward with lift instead of just detaching; light hits
ping a hubcap off first, saving doors for crashes that deserve them.
- Sparks on every impact, soft-puff smoke on wrecks and heavy damage, tyre
smoke while drifting (src/fx.gd -- procedural particles, radial-gradient
billboards, no textures). Camera shake on player crashes, applied after
look_at so it reads as the camera being knocked, not re-aimed.
- Crumple strength up ~40% now that scratches and dulling ride on it.
Traffic and parked cars inherit all of it via the shared fleet GLBs.
