Everyone in a car sits in an actual seat — driver front-left, shotgun, two rear

OP OpenVibers committed 31 Jul 2026 · 97e8f5bb40 · 1 file, +15 −15

The driver was glued to the car's center (my.x = car.x) and the shotgun
offset was subtle, so occupants looked stacked mid-car. seatPose() now places
every occupant at a car-local seat offset: driver (-.52,.35), shotgun
(.52,.35), rear (±.52,-.85) — applied while driving, in the post-step resync,
and for passengers. First-person driving now views from the driver's seat too.
