handling.meta

handling.meta file in GTA V, like in previous versions of the game, controls the physics and animations of vehicles in-game. This file is found found in ..\common\data and can be edited with any text editor.

Parameters

There are 50 parameters in 6 groups, plus additional sub handling data.

Physical Attributes

These seven values represent the vehicle's physical proportions within the game:

handlingName

This is used by the vehicles.meta file to identify the handling line of the vehicle.

Value: Any text string no more than 14 characters. By default, the handlingName consists of uppercase letters and numbers (TURISMO, E109, etc.)

fMass

This is the weight of the vehicle in kilograms. Only used when the vehicle collides with another vehicle or non-static object.

Value: 0.0 - 10000.0 and above.

fInitialDragCoeff

Sets the drag coefficient on the rage physics archetype of the vehicle (proportional to velocity squared). Increase to simulate aerodynamic drag.

This affects the maximum speed of the vehicle. Greater value will lower the maximum speed.

Value: 10 to 120

fDownForceModifier

Sets the amount of downforce applied to the vehicle. Increase this value to increase the grip at high speed.

Value: TBD

fPercentSubmerged

A percentage of vehicle height in the water before vehicle "floats". So as the vehicle falls into the water, at 85% vehicle height (seemingly the default for road vehicles) it will stop sinking to float for a moment before it sinks (boats excluded).

Value: any percentage expressed as a decimal (eg., 85% = 0.85). An invalid number will cause the vehicle to sink without the driver drowning, eventually teleporting the vehicle to the surface.

vecCentreOfMassOffset

This value shifts the center of gravity in meters from side to side (when in vehicle looking forward).

Value x: < -5.0 to > 5.0. (0.0 means that the center of gravity will be in the center of the vehicle. Positive values move the centre of gravity right.)

Value y: < -5.0 to > 5.0. (0.0 means that the center of gravity will be in the center of the vehicle. Positive values move the centre of gravity forwards.)

Value z: < -5.0 to > 5.0. (0.0 means that the center of gravity will be in the center of the vehicle. Positive values move the centre of gravity up. Changing this value to great negative quantities (E.G. -10 or greater) will cause the vehicle to behave erratically, moving many feet per frame.)

vecInertiaMultiplier

This value is resistance to rotation around each axis. Therefore, the x axis affects how quickly the car shifts forward and back under braking and acceleration and how it rotates end over end in the air, the y axis affects how quickly the car shifts from side to side when cornering (or in the air) and the z axis affects how the car rotates around the middle, which manifests in normal driving as how quickly the vehicle appears to react to steering inputs. Recommend keeping the z value above 2.0 unless you want arcade style immediate reaction to steering inputs

Note: Four cars do not respond typically to this value; the police3 (Police Interceptor), Gang Burrito, 190Z and Zion Classic. They need lower z values or else they will rotate too slowly.

Value x: < 0.0 to > 4.0.

Value y: < 0.0 to > 4.0.

Value z: < 0.0 to > 4.0.

Transmission Attributes

These values describe the vehicle's straight line performance. Rate of acceleration is determined by fDriveBiasFront, nInitialDriveGears, fInitialDriveForce, fDriveInertia, and fInitialDriveMaxFlatVel. Rate of deceleration is determined by fBrakeForce and fBrakeBiasFront. fSteeringLock can be thought of as a measure of sideways acceleration.

fDriveBiasFront

This value is used to determine whether a vehicle is front, rear, or four wheel drive.

Value: 0.0 is rear wheel drive, 1.0 is front wheel drive, and any value between 0.01 and 0.99 is four wheel drive (0.5 give both front and rear axles equal force, being perfect 4WD.)

nInitialDriveGears

How many forward speeds a transmission contains.

Value: 1 to 8 in versions before 1.0.1604.0. 1 to 10 for 1.0.1604.0 and up. Higher values work, but will exceed the gear ratio array and overwrite other data in the vehicle objects' data.

It is not recommended to have a value higher than 8 here as issues with downshifting can occur if the car's top gear is 9 or higher.

fInitialDriveForce

This value specifies the drive force of the car, at the wheels.

• fInitialDriveForce = TorqueWheelsNm/WeightKg

Value: 0.01 - 2.0 and above. 1.0 uses drive force calculation unmodified. Values less than 1.0 will in effect give the vehicle less drive force and values greater than 1.0 will produce more drive force. Most cars have between 0.10 and 0.40.

This value is calculated with the vehicle weight, so heavy and light vehicles have an accurate acceleration.

fDriveInertia

Describes how fast an engine will rev. For example an engine with a long stroke crank and heavy flywheel will take longer to redline than an engine with a short stroke and light flywheel.

• Drive inertia formula TBD

Value: 0.01 - 2.0. Default value is 1.0, or no modification of drive intertia. Bigger value = quicker redline

fClutchChangeRateScaleUpShift

Clutch speed multiplier on up shifts, bigger number = faster shifts. Recommended to not go over 13. A value of 1 = 0.9 seconds to shift gears.

fClutchChangeRateScaleDownShift

Clutch speed multiplier on down shifts, bigger number = faster shifts. Recommended to not go over 13. A value of 1 = 0.9 seconds to shift gears.

fInitialDriveMaxFlatVel

Determines the speed at redline in top gear; Controls the final drive of the vehicle's gearbox. Setting this value does not guarantee the vehicle will reach this speed. Multiply the number in the file by 0.82 to get the speed in mph or multiply by 1.32 to get kph. To find the right value for a given kph figure, kph * 0.75.

• TopSpeedKph = (fInitialDriveMaxFlatVel * 1.2) / 0.9

Value: 0.00 - 500.0 and above.

The top speeds for different gears can be calculated by replacing the 0.9 in the formula with the ratio of the specific gear. GTA V uses a ratio of 0.9 for the top gear by default.

fBrakeForce

Multiplies the game's calculation of deceleration. Bigger number = harder braking

• Brake Force formula TBD

Value: 0.01 - 2.0 and above. 1.0 uses brake force calculation unmodified.

fBrakeBiasFront

This controls the distribution of braking force between the front and rear axles.

Value: 0.0 means the rear axle only receives brake force, 1.0 means the front axle only receives brake force. 0.5 gives both axles equal brake force. A value between 0.01 and 0.49 means the rear axle will receive more brake force than the front and a value between .051 and 0.99 means the front axles will receive more brake force than the rear. In real life, normal vehicles usually have more front braking force than the rear (eg., 0.65).

fHandBrakeForce

Braking power for handbrake. Bigger number = harder braking

fSteeringLock

This value is a multiplier of the game's calculation of the angle a steer wheel will turn while at full turn. Steering lock is directly related to over or understeer / turning radius.

• Steering lock formula TBD

Value: 0.01 - 2.0 and above. Values around 0.1 - 0.2 will simulate a long wheelbase. Whereas a value of around 0.75 and above will turn extremely fast. To high of a value here will cause the vehicle to spin out too easily.

Wheel Traction Attributes

The following attributes describe how the vehicle will behave dynamically, from negotiating corners to acceleration and deceleration. This section has been updated from previous game versions.

fTractionCurveMax

(formerly fTractionMult)

Cornering grip of the vehicle as a multiplier of the tire surface friction. Effectively the peak grip status before any loss of grip.

fTractionCurveMin

(formerly fTractionLoss)

Accelerating/braking grip of the vehicle as a multiplier of the tire surface friction. Effectively the minimum grip status after losing traction, e.g. in a skidding situation.

fTractionCurveLateral

Shape of lateral traction curve (peak traction position in degrees). Lower values make the vehicle's grip more responsive but less forgiving to loss of traction. Higher values make the vehicle's grip less responsive but more forgiving to loss of traction. Also known as "slip angle".

fTractionSpringDeltaMax

Max distance of the lateral sidewall travel. Unit: meter. A force will pull the vehicle in the opposite direction of the lateral travel, most noticeable when stopping after a slide. The dynamic effect is a small force pulling the vehicle inwards of a corner, more noticeable as the sliding angle increases.

fLowSpeedTractionLossMult

How much traction is reduced at low speed, 0.0 means normal traction. It affects mainly car burnout (spinning wheels when car doesn't move) when pressing gas. Decreasing value will cause less burnout, less sliding at start. However, the higher value, the more burnout car gets. Optimal is 1.0. A completely artificial force.

fCamberStiffnesss

How much the vehicle is pushed towards its roll direction. Road camber also affects roll and applied forces.

Values smaller than 0.0 or greater than 1.0 create unrealistic forces.

fTractionBiasFront

Determines the distribution of traction from front to rear.

Value: 0.01 - 0.99. 0.01 = only rear axle has traction. 0.99 = only front axle has traction. 0.5 = both axles have equal traction. Entering a value of 0.0 or 1.0 causes the vehicle to have no traction (the tires actually fail to spawn), while entering a value outside of specified range causes the car to move irrationally whenever the wheels are touching the ground.

fTractionLossMult

How much is traction affected by material grip differences from 1.0. Basically it affects how much grip is changed when driving on asphalt and mud (the higher, the more grip you loose, making car less responsive and prone to sliding).

Suspension Attributes

fSuspensionForce

1 / (Force * NumWheels) = Lower limit for zero force at full extension. Affects how strong suspension is. Can help if car is easily flipped over when turning.

fSuspensionCompDamp

Damping during strut compression. Bigger = stiffer.

fSuspensionReboundDamp

Damping during strut rebound. Bigger = stiffer

fSuspensionUpperLimit

Visual limit... how far can wheels move up / down from original position

fSuspensionLowerLimit

Visual limit... how far can wheels move up / down from original position

fSuspensionRaise

The amount that the suspension raises the body off the wheels. Recommend adjusting at second decimal unless vehicle has room to move. ie -0.02 is plenty of drop on an already low car. Too much will show the wheels clipping through or if positive, no suspension joining the body to wheels

fSuspensionBiasFront

Force damping scale front/back. If more wheels at back (e.g. trucks) need front suspension to be stronger. This value determines which suspension is stronger, front or rear. If value is above 0.50 then front is stiffer, when below, rear.

fAntiRollBarForce

The spring constant that is transmitted to the opposite wheel when under compression larger numbers are a larger force. Larger Numbers = less body roll

fAntiRollBarBiasFront

The bias between front and rear for the antiroll bar(0 front, 1 rear)

fRollCentreHeightFront

The roll center height for the front axle, from the bottom of the model (road), in meters.

High values place the roll center closer to the center of mass, reducing body roll. Values placing the roll center higher than the center of mass will induce negative body roll - the "Tyrus Effect".

Low values increase the roll center distance from the center of mass, increasing body roll. Values placing the roll center too far from the center of mass may increase rollover chances.

Since center of mass differs per vehicle, using a visualization tool may help determining a desired amount of body roll.

fRollCentreHeightRear

The roll center height for the rear axle, from the bottom of the model (road), in meters.

High values place the roll center closer to the center of mass, reducing body roll. Values placing the roll center higher than the center of mass will induce negative body roll - the "Tyrus Effect".

Low values increase the roll center distance from the center of mass, increasing body roll. Values placing the roll center too far from the center of mass may increase rollover chances.

Since center of mass differs per vehicle, using a visualization tool may help determining a desired amount of body roll.

Damage Attributes

The following attributes dictate how the vehicle will react to damaging effects.

fCollisionDamageMult

Multiplies the game's calculation of damage to the vehicle through collision, causing gas tank and wheels to catch fire.

Value: 0.0 - 10.0. 0.0 = no damage through collision. 10.0 = Ten times damage through collision.

Higher values make body parts fall off more easily. Also enables engine damage.

fWeaponDamageMult

Multiplies the game's calculation of damage to the vehicle through weapon damage.

Value: 0.0 - 10.0. 0.0 = no damage through weapons. 10.0 = Ten times damage through weapons.

fDeformationDamageMult

Multiplies the game's calculation of deformation-causing damage.

Value: 0.0 - 10.0. 0.0 = no deformation through damage is possible. 10.0 = Ten times deformation-causing damage.

fEngineDamageMult

Multiplies the game's calculation of damage to the engine, causing explosion or engine failure.

Value: 0.0 - 10.0. 0.0 = no damage to the engine. 10.0 = Ten times damage to the engine.

This value seems to respond mostly to impacts directly on the hood, and not as much to front end impacts (particularly with taller vehicles).

fPetrolTankVolume

Amount of petrol that will leak after shooting the vehicle's petrol tank. Also used by some fuel-usage scripts.

fOilVolume

Black smoke time before engine dies?

Miscellaneous Attributes

fSeatOffsetDistX

The distance from the door to the car seat.

Value: Driver > passenger

fSeatOffsetDistY

The distance from the door to the car seat.

Value: Trunk > hood

fSeatOffsetDistZ

The distance from the door to the car seat.

Value: Undercarriage > roof

nMonetaryValue

AdvancedData

Advanced Data for the vehicle. Currently it is known to affect two different vehicle mechanics, the wheelies and the downforce, in a different way.

If the handbrake wheelie advanced flag is enabled (hardcoded to be enabled for all Muscle class vehicles), the AdvancedData will allow defined modparts to control the force multiplier for the wheelie.
If the new downforce mechanics advanced flag is enabled, the AdvancedData will allow defined modparts to control the downforce multiplier for the vehicle ONLY on the spoiler and front bumper parts.

Known Effects
Slot	Required Flag	Effect
Any	_AF_HANDBRAKE_WHEELIE	Adjusts the force of the handbrake wheelie.
0	_AF_DOWNFORCE_KERBFIX	Affects downforce.
1
20	_AF_HAS_SPECIAL_PERFORMANCE_MODS	Allows to increase or decrease engine power when Turbo is equipped.
22		Allows to increase or decrease engine power.

Index

Index of the mod part. For downforce altering, the index value is overall, and not based on type. Eg. Index value of 50 will affect the 50th (51st, if you start counting from 1) part listed in the modkit. The part at the chosen index must be classified as either a spoiler or a front bumper AND the new downforce mechanics advanced flag must be enabled for the multiplier to have any effect.

For wheelie force altering, the index value is based on type. Eg. if the chosen modpart is at index 20, but it is the second part of a specific class, then the index will be 1 and not 20. Slot value must be correctly defined, and the handbrake wheelie advanced flag must be enabled on the vehicle in order for the multiplier value to have an effect.

Value

The multiplier value.

strFlags

Flags that adjust the behavior of the special flight feature.

Special (Flight) Flags
HEX	Name	Description
0x1	_SF_DISABLE_THRUST_HATCH	Disables movement of the "misc_c" bone, which is used as a hatch hiding the thrusts. See: Deluxo. Additionally, using the handbrake will fold the extended wings.
0x2	_SF_UNK_1	Unknown.
0x4	_SF_REDUCED_CLIMB_RATE	Reduces the rate at which the vehicle gains altitude while giving it additional hovering velocity.
0x8	_SF_HB_SMOOTH_LANDING	Using the handbrake makes the vehicle will gradually hover down to the ground. In addition, the player will not bail from the vehicle when using "exit vehicle" input, instead having the same effect. This seems to only affect bikes/Oppressor Mk II.
0x10	_SF_ENABLE_STABILITY_ASSIST	Enables the fStabilityAssist value. Causes the vehicle to 'snap' towards the original direction it was heading in, in the event that the player turns left or right. This makes the vehicle less 'slidy' and easier to control in hover mode.
0x20	_SF_UNK_5	Unknown. Used by Oppressor Mk II.
0x40	_SF_INCREASE_PITCH_ANGLE	Slightly adjusts the maximum pitch angle of the vehicle.
0x80	_SF_PERMANENTLY_HOVERING	Permanently places the vehicle in hover mode. Hover mode cannot be switched off.
Flag names prefixed with an underscore are unofficial and/or based on guesswork or observations.
