  Motion trail: How to invert a path direction ?

  Posted by Christophe Charbonnier on November 3, 2008 at 10:02 am

  Hello,

  In order to do a “motion trail” effect, I am applying a vegas effect on a path with just 1 segment and I am animating the rotation attribute. The thing is the motion is “counter-direction”. I want it to turn the other side. I have found a workaround (by inverting the first/end opacity and the rotation evolution), but this does not work when I must stop the motion (by stopping the rotation, and fade-out the length attribute).

  I only want to tell vegas-effect to change the direction of my path.
  I tried to change the first vertex of my path, but this does not work…

  Does somebody know how I can change the direction ???

  HAve you tried TIme Reversing the keyframes that you currently have? With Vegas, you either rotate clockwise or counter clockwise. You may also want to exchange the start and end opacity values.

  I was just having the same problem and came up with an answer that worked for me. The time reversing idea would’nt work because that would put the trail of my light streak following the motion path ahead of it’s source. Instead I flipped the solid around (-100 on X) so that the motion path would also travel in the reverse direction.

  You can invert the Vegas stroke by setting the start opacity to 0 and the end opacity to 1.
