Hi, For a car simulation, I've made some tests with JointSuspensions, but I've realized that it's not possible to keep real mass values for the bodies without getting instability. The physics car demos have still "fake" values like gravity of -19.6 or a car mass of 4Kg to get better mouvement. It would be great if you improve this. Regards, Philippe

Hi, In Unigine script, I'm tring to create a vehicle with 4 wheels using 4 JointSuspension, but I enconter a problem : I encounter a lot of jittering, the vehicle doesn't stop to bounce on the ground. For information, my vehicle has a mass of 1000 and each wheel (a sphere shape) has a mass of 20, (ratio of mass_vehicle / mass_wheel = 500). I've tested also in your car_00.cpp physics demo, I've noticed that the body of the car has a mass of 64 and the wheels a mass of 33.5 each (ratio of almost 2). When I reduce the mass of the wheels (3.3 for example) for a ratio of almost 20, it begin to bounce. How can I have more stability with JointSuspension ? Philippe
