I am truly surprised that such a simple scene as 2 scans running a circle in opposite direction, is not possible on mydmx !?
I mean, when I use the FX Gen for the first scan, I create the circle and set the direction. Ok, fine.
Then I generate the scene, by choosing the max number of steps I get
100 steps (andnot 10 as specified by the soft).
I believe 100 steps is good to get a smooth circle, and not that 8 dots geometrics...
So go ahead and manually set the second scan to move in opposite direction for the 100 steps...
Good luck on that !
