  How do I control the rotation speed using CC Sphere

  Posted by David Cabestany on December 3, 2011 at 1:20 am

  I’m animating a globe using a map with CC Sphere, to make it rotate I’m applying a “time*” expression to the y axis, since I need it to rotate very fast at the beginning and then slow down I applied the multiplier to an expression slider control which is keyframes from 1200 to 25. However All I’m getting is the globe to rotate at a certain speed at the beginning) and then rotate super fast and in the opposite direction when it moves from 1200 to 25, looking at the values I see that the rotation is going backwards from 9x+323.6 (highest rotation attained) to 91.8 (time*25 at the time of my last keyframe.

  Evidently the fact that the time keeps going up but the degrees reset itself each 360 is messing up the speed, is there an expression that can control the speed without making it go in the opposite direction?

  Thanks in advance.
