Gearbox always be stuck at the first gear

[CN_Lurker_1011 1]

Main code:                MOI=16;
                                    dampingRate=1;
                                    dampingRateInAir=1;

Not sure whether you've already resolved the issue so just in case, I would get your attention to the apparently too high

idleRPM = 1000; 

in your PhysX config. If the engine cannot go lower than that, it cannot reach the lower RPMs calculated for the higher gears as shown on your first screenshot.

this parameter is only used by sound simulation and doesn't affect vehicle driving at all. MinOmega affects actual minimal RPM in simulation.

 

You need to tweak dampingRate params most likely

If vehicle is too slow, then lower the param. If its too fast, then increase it. It's sort of magic parameter so you have to figure it out via trial & error method so usage of diag_mergeConfigFile is sort of mandatory. Keep in mind also that dampingRate & dampingRateInAir should be using same number.

        dampingRate                = 3145.0;
        dampingRateInAir        = 3145.0;

 

MOI should be calculated this way

        MOI            = __EVAL(1.1*(0.5*193*(0.378626^2)));        // radius 0.378626m

Yeah, obviously you're right. I must have had been dizzy afterward a party.
