wake

Instances (soft cards) in world space behind the eggplant car's rear wheels: lilac tyre-smoke puffs that grow and rise (smoke puffs per second) and pale-cyan spray streaks thrown off the wet road that fall back under gravity (spray drops per second). It emits at the two points its lx ly lz and rx ry rz inputs name (the car updates them every frame; plain numbers, so moving them never restarts the sim), so what it already emitted stays behind as the car drives on. Outputs smoke and spray.
