Expression Glitch with Auto-Orient?

[Filip Vandueren]

If you go to frame 1 then purge the ram, and preview again, do you still get the same results ?
Do all the layers do it or only the ‘followers’ ?

Tried it on 2 different computers. It seems to just be the followers that are having the problem. I tried adjusting the rotation, but that didn’t help.

Possbile work around … any way to have it output the auto-orient value to a expression variable?

Have you seen Dan Ebbert’s page on Trails?

https://www.motionscript.com/mastering-expressions/follow-the-leader.html

At the bottom of the page the are Orientation issues covered, in the sections titled, Follow the Null and Auto-orient.

Maybe it will help some.

If you want the follower layers to have the same orientation as the leader layer, but time delayed, apply this expression the their rotation property (leave auto-orientation off for the followers):

delay = 0.25;
t = time – delay;
L = this_comp.layer(“leader”);
x = L.toWorldVec([1,0],t);
radiansToDegrees(Math.atan2(x[1],x[0]));

Thank you, that did the trick with a little modification for my needs (300 followers). It also sped up my render time by a ton!
