Chaos Vehicles controllability: turning and skidding

[JediSkywalker2]

Hi

I’ve finally managed to get a drivable Chaos Vehicle BP after testing the standard PhysX one. What is really disappointing about Chaos Vehicle, it’s its controllability. I raised and moved right points on Steering Curve to have better steering 60 KmH, but it didn’t help: it still takes ages to turn right or left at this speed. Also, I can’t make the car to go skidding (sliding).

After that I changed Wheel Settings Longitudal friction force multiplier to 3 and lateral one to 5, it got slightly better, but I still wonder how to improve that.

Wondering that by myself too, very weird behavior.
If you figured something, hope you wouldn’t mind sharing.

Maybe you guys can help…

Found bugs

In this thread I will post all the bugs I find. Engine\Source\Runtime\Experimental\ChaosVehicles\ChaosVehiclesCore\Private\WheelSystem.cpp Line 120 // use slip angle to generate a sideways force if (Setup().LateralSlipGraph.IsEmpty()) { float AngleLimit = FMath::DegreesToRadians(8.0f); if (SlipAngle > AngleLimit) { SlipAngle = AngleLimit; } else if (SlipAngle < AngleLimit) { SlipAngle = AngleLimit; } FinalLateralForce = SlipAngle * CorneringStif…

Adventures in UE5 vehicle land

If there’s a better place for this let me know… I’ll be trying to implement a few vehicle types derived as much as possible from UE4 version I have, and give as much feedback as possible here. The first up is a plane sim and a fly through of my ue5 mapping experiment. I’ll reply later a write up of the technical issues, etc… v=3YCXkTn3eMA

Have you tried doing the same in latest Unreal engine 5 version?

4.27-chaos is a newer chaos version than the ue5 ea copy, its the current active iteration branch (though they have been merging to ue5 EA you would have to download a source copy).
