So, i'm having problems with the physx of this vehicle. Going forwards or backwards is fine but when i turn the tank, regardless of if i'm accelerating or not, it accelerates a lot; and if I press A-D repeatedly the tank accelerates a lot more, Once i got it to 3200 km/h. I suspect this has to do with the model of the tracks or a misplacement of memory points, but i have no idea Video Physx simulation = "tankX"; dampersBumpCoef = 0.30000001; terrainCoef = 0; fuelCapacity = "650 * 0.165"; ACE_refuel_fuelCapacity = 650; maxOmega = 251.33; minOmega = 83.78; enginePower = 530; peakTorque = 2000; engineMOI = 20; idleRpm = 800; redRpm = 2400; clutchStrength = 50; dampingRateFullThrottle = 0.25; dampingRateZeroThrottleClutchEngaged = 8; dampingRateZeroThrottleClutchDisengaged = 0.25; maxSpeed = 75; thrustDelay = 0.050000001; brakeIdleSpeed = 2.8; normalSpeedForwardCoef = 0.6; slowSpeedForwardCoef = 0.1; tankTurnForce = 150000; tankTurnForceAngMinSpd = 0.75; tankTurnForceAngSpd = 0.75; accelAidForceCoef = 6; accelAidForceYOffset = -2; accelAidForceSpd = 10; torqueCurve[]= { { "(0/2500)", "(0/2350)" }, { "(357/2500)", "(1900/2350)" }, { "(714/2500)", "(2100/2350)" }, { "(1071/2500)", "(2250/2350)" }, { "(1428/2500)", "(2350/2350)" }, { "(1785/2500)", "(2350/2350)" }, { "(2142/2500)", "(1965/2350)" }, { "(2500/2500)", "(0/2350)" } }; waterPPInVehicle=0; maxFordingDepth=-0.65; waterResistance=0; canFloat=0; waterLeakiness=15; antiRollbarForceCoef=50; antiRollbarForceLimit=20; antiRollbarSpeedMin=10; antiRollbarSpeedMax=65; class complexGearbox { GearboxRatios[]= { "R1", -23, "N", 0, "D1", 50, "D2", 40.123, "D3", 28, "D4", 23, "D5", 18.6, "D6", 16.2, "D7", 13.91 }; TransmissionRatios[]= { "High", 1 }; gearBoxMode="auto"; moveOffGear=1; driveString="D"; neutralString="N"; reverseString="R"; }; changeGearType="rpmratio"; changeGearOmegaRatios[]= { __EVAL(2400/2400) , __EVAL(1000/2400), // R1 __EVAL(800/2400) , 0, // N __EVAL(2350/2400) , __EVAL(1900/2400), // D1 __EVAL(2350/2400) , __EVAL(1900/2400), // D2 __EVAL(2100/2400) , __EVAL(1900/2400), // D3 __EVAL(2200/2400) , __EVAL(1900/2400), // D4 __EVAL(2200/2400) , __EVAL(1900/2400), // D5 __EVAL(2200/2400) , __EVAL(2000/2400), // D6 __EVAL(2350/2400) , __EVAL(1900/2400) // D7 }; switchTime=0; latency=1.5; engineLosses=25; transmissionLosses=15; driveOnComponent[]={}; wheelCircumference=2.2; numberPhysicalWheels=16; turnCoef=5; class Wheels { class L2 { boneName = "wheel_podkoloL1"; center = "wheel_1_2_axis"; boundary = "wheel_1_2_bound"; steering=0; side="left"; mass=150; width=0.51999998; MOI=14; latStiffX=2.5; latStiffY=50; longitudinalStiffnessPerUnitGravity=18000; maxBrakeTorque=37500; sprungMass=3125; springStrength=264063; springDamperRate=17236; dampingRate=260; dampingRateInAir=260; dampingRateDamaged=10; dampingRateDestroyed=10000; maxCompression=0.15000001; maxDroop=0.15000001; frictionVsSlipGraph[]= { {0,0.5}, {0.34999999,1.2}, {1,0.5} }; }; class L3: L2 { boneName = "wheel_podkolol2"; center = "wheel_1_3_axis"; boundary = "wheel_1_3_bound"; }; class L4: L2 { boneName = "wheel_podkolol3"; center = "wheel_1_4_axis"; boundary = "wheel_1_4_bound"; }; class L5: L2 { boneName = "wheel_podkolol4"; center = "wheel_1_5_axis"; boundary = "wheel_1_5_bound"; }; class L6: L2 { boneName = "wheel_podkolol5"; center = "wheel_1_6_axis"; boundary = "wheel_1_6_bound"; }; class L7: L2 { boneName = "wheel_podkolol6"; center = "wheel_1_7_axis"; boundary = "wheel_1_7_bound"; }; // rear left wheel, usually Idler or Drive Sproket // Note, this wheel may not always be touching the ground, but we need it anyway! class L9: L2 { boneName = "wheel_podkolol9"; center = "wheel_1_9_axis"; boundary = "wheel_1_9_bound"; maxCompression = 0; maxDroop = 0; sprungMass=0; }; // front left wheel, usually Idler or Drive Sproket // Note, this wheel may not always be touching the ground, but we need it anyway! class L1: L2 { boneName = ""; center = "wheel_1_1_axis"; boundary = "wheel_1_1_bound"; maxCompression = 0; maxDroop = 0; sprungMass=0; }; class R2: L2 { boneName = "wheel_podkolop1"; center = "wheel_2_2_axis"; boundary = "wheel_2_2_bound"; side = "right"; }; class R3: R2 { boneName = "wheel_podkolop2"; center = "wheel_2_3_axis"; boundary = "wheel_2_3_bound"; }; class R4: R2 { boneName = "wheel_podkolop3"; center = "wheel_2_4_axis"; boundary = "wheel_2_4_bound"; }; class R5: R2 { boneName = "wheel_podkolop4"; center = "wheel_2_5_axis"; boundary = "wheel_2_5_bound"; }; class R6: R2 { boneName = "wheel_podkolop5"; center = "wheel_2_6_axis"; boundary = "wheel_2_6_bound"; }; class R7: R2 { boneName = "wheel_podkolop6"; center = "wheel_2_7_axis"; boundary = "wheel_2_7_bound"; }; // rear right wheel, usually Idler or Drive Sproket // Note, this wheel may not always be touching the ground, but we need it anyway! class R9: R2 { boneName = "wheel_podkolop9"; center = "wheel_2_9_axis"; boundary = "wheel_2_9_bound"; maxCompression = 0; maxDroop = 0; sprungMass=0; }; // front right wheel, usually Idler or Drive Sproket // Note, this wheel may not always be touching the ground, but we need it anyway! class R1: R2 { boneName = ""; center = "wheel_2_1_axis"; boundary = "wheel_2_1_bound"; maxCompression = 0; maxDroop = 0; sprungMass=0; }; };

this solved my problem, thanks

I have a problem with the tank, when trying to climb a hill or when going through rough terrain the tank just slides. I tested the merkava that comes with the game and i couldn't replicate the problem

As the title says, i have a problem with the physx.hpp and the tank only reaches 12kph, it doesn't change gears.
