The straight strip becomes a closed rounded-rect loop (~7,400 studs/lap)
built from centerline samples, Shuto-C1 style. Landmark zones:
- Daikoku Futo PA: drivable meet lot off the south straight (guardrail
gap entrance), painted bays, flood-light towers, bilingual sign —
cars now SPAWN at Daikoku like a proper meet
- Rainbow Bridge over the east straight: white suspension towers with
beacons, cross beams, rainbow-colored rail lights
- Odaiba beyond the bridge: blocky Unicorn Gundam (glowing eyes, horn,
pink psycho-frame strips) + 16-cabin neon ferris wheel
- Yamate-style tunnel enclosing the whole north straight
- Tokyo Tower replica (orange/white tiers, two lit decks, antenna) west
- Tatsumi PA overlook pad NE
- City-core skyline inside the loop + outer ring skipping landmark zones
- Bilingual green highway signs via SurfaceGui (JP + EN)
Gameplay contract preserved: SpawnPad/FinishLine/KillWall names intact,
kill walls hug every road edge except the Daikoku entrance.
- Scanned b-action-cam-footage/clipchamp (99GB, 5 videos of the FD):
extracted audio NAS-side via linuxserver/ffmpeg container (stream-copy),
scanned 69min return drive per-second for engine tonality + whistle
prominence (1.5-9kHz peak vs band median)
- New rev loop: 985-993s highway pull — 0.0Hz pitch drift over 8s,
whistle ~1.7kHz at +33dB, exhaust + turbo captured together (seam 0.001)
- New whistle-only loop: same pull high-passed 1.2kHz — isolated spool
- SoundController: optional per-car Whistle layer that rides boost
(throttle held at speed): fades in past 25% speed, pitch 0.9->1.35
- ROTARY_SOUND.md updated; three .ogg uploads needed in Studio now
- SoundController rebuilt around idle+rev loop crossfading (real racing
game approach): idle layer barely pitch-shifts (keeps engine character),
rev layer carries the speed range; crossfade window 5%-45% of top speed
- Per-car CAR_SOUNDS table so the RX-7 gets real 13B rotary loops while
other cars keep the generic set
- docs/ROTARY_SOUND.md: full record->loop->upload pipeline for capturing
the owner's REAL RX-7 (extract audio from video, zero-crossing cut +
equal-power crossfade seam, normalize, ogg, Studio upload, wire IDs)
- Toolbox rotary rips evaluated and rejected: unauditionabe off-platform,
short/unloopable, murky rights; the real car beats any rip
SoundController (client):
- Looping engine sound on the car body: pitch 0.7->1.9 tracks speed
(curved so low speed feels torquey), volume swells with throttle
- Tyre squeal loop faded by lateral slip (velocity along body RightVector)
and hard braking from speed; always playing at 0 volume to avoid pops
- 3D sounds with rolloff so other players hear cars pass
- Asset IDs from safe sources (Roblox Resources engine loop,
ProSoundEffects squeal); swap in SOUNDS table after audition
Ambience (server):
- Atmosphere (purple-grey haze, glare) so neon reads in the air
- BloomEffect for neon pop + subtle cool ColorCorrection
- Slow ClockTime ping-pong 22:00->03:00 over 10 min: always night,
but the sky breathes
CameraController (client):
- Scriptable chase cam only while in the DriveSeat; restores default on exit
- Frame-rate independent damped follow with look-ahead aim point
- Flat horizon (ignores car pitch/roll) so bumps don't shake the view
- Speed-based FOV kick (quadratic ramp) for sense of pace
- Cleans up on Died/despawn
MapBuilder v2:
- Highway extended 2400 -> 3200 studs with distinct feature zones
- Gantry arches (seg 2), enclosed neon-lit tunnel (seg 3), jump ramp +
landing pair on the right lane (seg 4, left lane stays flat)
- Procedural neon skyline towers flanking both sides (deterministic seed,
same city every server)
- End kill-wall so you can't sail off the far edge
- New shared Chassis.luau: geometry constants + per-car tuning from stats
- CarManager.buildCarModel rebuilt: prismatic+spring suspension per corner,
servo-hinge steering on front knuckles, motor-hinge driven wheels,
hidden dense ballast for anti-roll; VehicleSeat kept as input device only
- New client ChassisController: drives motors/servos from seat
ThrottleFloat/SteerFloat per Heartbeat; speed-sensitive steering lock;
engine braking on throttle release
- Driver gets network ownership of every unanchored part (constraint
assemblies are separate; missing one causes stuttery physics)
- Docs: MESH_SWAP.md rewritten for shell-on-chassis workflow; ROADMAP updated
Per user direction, the MVP is now simply driving cars on the expressway.
- Removed RaceManager and Economy modules entirely
- Slimmed Remotes to DataUpdated / SpawnCar / EquipCar
- ProfileTemplate now just remembers the last driven car (v2)
- Cars: dropped price/rep/upgrade fields; kept identity + driving stats
- CarManager: stat-based tuning only; RX-7 allowlist via GameConfig.canDrive
- DataManager: assign default car on join; downgrade RX-7 if de-allowlisted
- Client: replaced garage/economy UI with a simple car picker + respawn
- Docs: GDD/ROADMAP/README rewritten for drive-only; added docs/MESH_SWAP.md
- Gates: stylua clean, selene 0/0, rojo builds
