Riven Impact Dynamics

• —New sound settings in riven_settings.lua: SeatbeltVolume = 0.45 (buckle/release clicks and the unbuckled alarm, was full) and TyreScreechVolume = 0.35 (bare rim or metal on the road, was full). Also available as Config.UI.SeatbeltVolume and Config.Audio.ScreechVolume.
• —New idle sleep (client/client_idle.lua, Config.Performance, switch Features.IdleSleep): while you're on foot with nothing moving within 60 m, no crash debris nearby and no crash of yours in the last 20 seconds, the script's looping parts and the brakes check only every 2.5 seconds. The archive notes about 381 to 40 loop wake-ups a second on foot, measured offline.
• —Per-frame effects (cracked glass, glowing brakes) and one-off sequences (repairs, animations) are never slowed; getting in a car, a car coming past or a crash wakes everything at once.
• —The hood and trunk lock no longer runs every frame while you're on foot.

Customer release. Released as riven-impact-dynamics_SECURED-v9.9.4-idle.zip. Release confirmed availability, not in-game testing.

• —New client/client_rollover.lua and Config.Rollover.Real (switch Features.RealRollPhysics) replace the old fixed push-over.
• —Each car gets a stability profile from its track width and centre-of-gravity height: a van tips on about a 47 degree slope or about 0.86 g of cornering; a low sports car needs about 63 degrees or 2.5 g.
• —Cars can roll from a sideways slide that suddenly catches, sliding sideways onto grass, dirt, mud, sand or gravel, a slope steeper than the car can stand on, a hard T-bone on a tall vehicle, or cornering harder than a top-heavy vehicle can take.
• —Sideways speed becomes roll speed: a slow trip lays the car on its side, a fast one tumbles it over and over. Each landing damages the side or roof that touched, and a car on its roof or side scrapes to a stop.
• —Occupants are hurt on every landing (60% less when belted), get a camera jolt, and someone unbelted can be thrown out through their window.

Customer release. Shipped in the idle build; removed again in the rollswitch build.

• —New client/client_bikecrash.lua and Config.BikeCrash (switch: Features.BikeCrashes): hard hits throw the rider and passenger off — over the bars in a frontal hit (30+ km/h), sideways from a side hit (40+), and only a big rear-ender (55+). Distance and height follow your speed.
• —A bike that goes down on its side at speed slides you off along the road with road rash while it grinds and throws sparks; a slow tip-over just drops you off.
• —A helmet takes 30% off the crash injury, daze and knockout.
• —A severe front hit bends the forks so the bike pulls to one side (synced) until repaired; hard hits can burst the front or rear tyre.
• —GTA's own knock-off is set to hard so small bumps no longer throw you at random, and if GTA throws you off first the crash injury still counts.

• —New client/client_vehguard.lua (loads right after the license): helicopters, planes and every class in Config.IgnoredClasses are no longer affected by flat or burst tyres, tyre thumps, speed caps, leaks, scrapes, traction handling, stalls, health or fuel drops, window smashing or torn-off panels. Repairs still work. Switch: Config.VehicleGuard.
• —The hood and trunk lock now leaves aircraft doors (cargo doors and ramps) alone.

• —New client/client_lidlock.lua (loads right after the license): the hood and trunk lid can no longer fly up, swing open, pop open or fall off from this resource's crash damage, buckled-hood peak, loose lids, soft-body panel pop, fire lifting the hood, or synced/replayed damage.
• —If GTA physics pops a lid up while driving or in a crash it is shut again at once (your own car every frame, other cars 10 times a second).
• —/fieldrepair can still open the hood, and other resources can still open a parked car's trunk. Switch: Features.LockHoodTrunk in riven_settings.lua (on by default).
• —Config: HoodBuckle.Enabled = false, HoodHangScale = 0, and all HoodBreakOffChance values set to 0.

• —Removed the driver, passenger and curtain crash-prop airbags, their models and texture, and the Config.CrashProps.Airbags setting.
• —Removed the Airbags / AirbagsFrom quick settings and /crashpropstest airbags command. The archive changelog states that other behavior is unchanged.
• —Updated stream/riven_crash_props.ytyp to list the remaining 80 models.

Customer release. Released as riven-impact-dynamics_SECURED-v9.9.4-noairbags-2.zip (byte-identical to the noairbags archive). Release confirmed availability, not in-game testing.

• —A burst tyre you keep driving on now goes onto the rim so the shredding models show it coming apart: peeling for 400-900 m, shredded until 1.5-3 km, then a few strips (Config.CrashProps.Tyres.ShowFromBurst, Stage2At, Stage3At; barely faster at speed). A parked car's flat stays a flat.
• —Crash tyre bursts are rarer: Config.Visual.TyreBurstChance 0.04 / 0.20 / 0.45 (was 0.25 / 0.60 / 0.80).
• —GTA-flat tyres last 600-1500 m before going onto the rim (Config.Flats.Shred.Meters, was 150-450; FastAt 60).
• —New test commands: /tyredebug shows what each wheel is doing (flat/rim, shredding stage and model, fire stage, melted model, tyre size, streaming), and /crashpropstest melt [3|4|5|0] puts the melted tyres on your car without a fire. A missing model now prints a red warning in F8.

Customer release. Current customer archive: riven-impact-dynamics_SECURED-v9.9.4-melt2.zip. Release confirms availability, not in-game testing.

• —Melted tyres in fires: when Riven Burn Dynamics melts a tyre it slumps on the rim, blistered and dripping (stage 3), collapses to a charred crust (4), then burns away to the bead wires (5). Molten rubber pools under it and an ash ring is left. Settings: Config.CrashProps.BurntTyres.
• —Crash tyre bursts now go flat first instead of straight to the rim; after 150-450 m (Config.Flats.Shred.Meters, was 300-900) the tyre shreds on the rim, throwing rubber behind the car (further the faster you go). Config.Flats.CrashBurstOnRim = true restores the old behaviour.
• —Tyre gauge is now a pencil gauge held while kneeling, with a sliding scale bar and psi/kPa readout; /tyregaugetest tunes how it sits in the hand (Config.TyreCare.Gauge.Prop).

Customer release. Archive: riven-impact-dynamics_SECURED-v9.9.4-melt.zip. Release confirms availability, not in-game testing.

• —Built-in Riven Crash Props (stream/riven_crash_*): glass cubes, lens and grille shards, trim, colour-matched side mirrors, headlight assemblies, muffler, hubcaps and a torn liner join the crash debris pieces; window glass piles get the cubes.
• —New crash-scene effects: fluid puddles that spread under a wrecked car, /absorbent for responders, a debris mat at the point of impact, airbags that hang until the car is repaired, and tyres that shred apart on the rim while driving, throwing rubber onto the road. Seeded from the crash so every player and late arrivals see the same scene. Settings: Config.CrashProps; test with /crashpropstest tyre | airbags | scene | clear.
• —Tyres pick up nails about 7x less often: Config.Flats.RoadDebris.PerKm 0.02 to 0.003 (about one every 330 km instead of every 50 km).
• —Tyre pressure gauge: /tyregauge at a wheel shows its psi on a dial (amber when low, "losing air" while leaking); in the driver seat it reads all four. Bindable key.
• —Fix a leaking tyre: /plugtyre at the wheel (8 s) plugs it and pumps it back up before it goes flat; works on other players' cars. Settings: Config.TyreCare.
• —New riven_settings.lua quick-settings file: one short file with a true/false switch for every part of the script and the numbers servers change most; it wins over riven_impact_config.lua.

Customer release. Current customer archive: riven-impact-dynamics_SECURED-v9.9.4-crashprops.zip. Release confirms availability, not in-game testing.

• —Flat-tyre and slipping-gearbox speed limits now apply only while the car is on all four wheels, so falling and rolling vehicles are no longer slowed by the ground-speed cap.
• —After landing, the limit eases back in from the landing speed; short bumps under 0.3 seconds do not reset it. Settings: Config.Mechanical.CapOnGroundOnly, CapFallSpeed and CapAirGraceMs.

Customer release. Current customer archive: riven-impact-dynamics_SECURED-v9.9.4-fall.zip. Release confirms availability, not in-game testing.

• —Your own picture on the debris licence plate: save a picture as textures/plate.png and restart the resource, and the plate that comes off in a crash shows it for every player. No picture keeps the original plate. Setting: Config.Debris.PlateTexture; the original is in textures/plate_template.png to paint over.
• —The plate picture now sits in its own texture file (stream/k3_debris_plate_txd.ytd) instead of inside the plate model, so it can be swapped; client/client_plate.lua swaps your picture in at startup.
• —Client scripts moved into client/ (client_*.lua, license_client.lua, riven_brakes_loader_client.lua); fxmanifest.lua and the tools tests point there. Shared and server scripts, settings, and riven_burn_visual.lua stay next to fxmanifest.lua.

Installation note. Replace the whole folder when updating, so old root copies of the client files don't linger.

Build notice. In-game behavior and Cfx.re escrow are not verified.

• —Low-speed crashes no longer wreck the car: added bumper elastic give and a low-speed ramp, and the engine now starts further behind the bumper. A 10 mph pole hit leaves roughly 20 cm of crush with the engine untouched; behavior at 45 km/h and up is unchanged.
• —Riven Brakes updated to its 1.0.0 (11) release with original files untouched: brake squeal on cold and very hot brakes and hot-brake cooling ticks, with a new Config.Brakes.Enabled switch.
• —Fire fixes: a burning car is marked as lit so the fire guard no longer fights the fire; a fire-killed car reads as destroyed in the crash state so cranking fails; burning wrecks keep their crash dents.
• —Built-in Riven Burn Dynamics visual damage: burning cars split into zones that heat and spread, with staged damage from buckled hoods to burnt-out shells, logged and replayed so every player sees the same car.
• —Fuel-tank fires no longer blow the car up: all three GTA fire health pools are held four times a second, with a new Config.GameFire setting.

Customer release. Current customer archive: riven-impact-dynamics_SECURED-v9.9.4-firefix-7.zip. Release confirms availability, not in-game testing.

Build notice. Source archive declares version 9.9.4 (firefix-7). In-game behavior and Cfx.re escrow are not verified.

• —Restricted wheel detachment to catastrophic crash conditions rather than ordinary severe impacts.
• —Adjusted wheel-detachment thresholds and probability settings.
• —Changed the default trunk behavior so impacts crease and buckle the trunk lid instead of detaching it. The previous behavior remains configurable.

• —Reduced radiator damage from light impacts and adjusted overheating thresholds.
• —Improved hood-retention handling for vehicle copies seen by other players.
• —Introduced an individual /impactsettings menu for supported screen and camera effects.

• —Adjusted how suspension landings and rough-road impacts affect vehicle components.
• —Reduced some non-crash component damage caused by routine suspension hits.
• —Added configurable ULC parking and driving pattern integration where ULC is installed.
