Hello. My posting is the first time. I am making CAR model with Box, Sphere & Hinge2 Joint. My wheeling is implemented by Hinge2's first Histop, Lowstop. In HIGH fps(Frame/Sec), wheeling is sharp, it means steep curve. But in LOW fps, it's slow curving. I don't know what's the wrong. Or maybe my approaching on hinge2 model is wrong?
