Hi All, I'm very new to unity (matter of days) and have been slowly working my way through tutorials and learning extra JS to cover all bases! Anyway, after feeling like I have been doing well I decided to try something a bit more complicated and make a simple racing game, after multiple youtube tutorials I've pretty much got everything down except that the wheel colliders will not collide with the plane mesh leaving the car sitting on its box collider with the wheels submerged. I've tried all the obvious stuff like starting a car from a height and dropping onto the plane, making a concurrent plane with box collider, making radius of wheel colliders bigger than wheel etc. but none of it seems to have any effect!?! If anyone had any ideas what I'm missing I'd be hugely grateful!
