I was wondering if anyone has a guide or pointers to get unity 4 physics based assets working with unity 5. Car controllers, vehicle controllers, hand controllers, rope controllers....none of it work when I import into unity 5. Hand and rope controllers go all bonky, the joints they control leap all over the place. Vehicles tend not to get off the ground -- but sometimes once they are moving they are ok, other times they just won't move at all. There must be some value(s) that can be tweaked without rewriting all the scripts? Please help! The physics in unity 5 is freaking awesome, it would be a shame to have to pass it up for subpar u4.6 physics just because I cant get some assets to work.
