Hi ,
When I animate the 4 wheeler ext using Keypad or the autonomous mode my wheels are not getting the exact roation they seem to rotate backwards...Could you please help me to solve this issue....!

hi bineshraj.

What you experience is not a real effect, it is simply a frame rate effect (an "optical illusion"). It is the effect you see on the horse carriage's wheels in western movies. The reason is that when the wheel starts rotating fast enough it will repeat itself at the next frame and then if it spinns faster it will look as if it rotates backwards.
But here is the good part: the 4WExt wheel is rotating correct inbetween the frames so that your motion blur will be nice as expected. To see this you can increase the fps say 10 times and link/parent for example a box to the wheel and then move the timeslider manually one frame at the time, and you will see that the wheel actually rotates exactly as it should.
