Hi guys, I am working on a Truck Trailer, The truck head and carriage are two seperated wheeled vehicle actor, which are attached by a physics constraint, only the head has power(throttle), however the carriage’s rear wheels are not rotating as expected, it rotates for a second at first when the head starts to move, and then seems to stuck there, behaviours like a real car had it’s hand brake on.
I’m sure my physics settings and vehicle settings and vehicle animblueprint are perfect-I’ve been working on these stuff for some time.
I also tried to manually set the carriage’s brake and handbrake to 0.0/off,still not working.
When I set the throttle of the carriage to 1, the wheels works perfectly, so i doubt that there’s some kind of engine resistance or auto locking system going on behind the scene. I tried to set “Damping rate zero throttle”, “damping rate full throttle”, "Clutch Strength"etc. to zero, but nothing changeds.
Anyone knows what’s going on?
