Hello Dan, thanks again!
Yes your expression actually works well ! I just changed the y and x coordinates in it to x and z :…(v[0],v[2])

Only a little problem with the z axis of my Null facing the back (like starting à 180°) when adding the expression to it.

Thanks really much for your clarification on this ! Love it, it’s pretty close from the ‘Auto-orient Y Only’ in your Expressioneer’s Design Guide, but with transform.position.velocity.
This rocks, 🙂

Hello Dan,
thank you for the answer! Yes I finally found that later on, actually I’m hitting on another problem…
After I linked this layers expressions to a Null in my main composition
this way :
angle = comp("MainComp").layer("Null1").transform.yRotation%360;
minAngle = -11,25;
maxAngle = 11,25;
if (angle < minAngle || angle > maxAngle) 0 else 100
I’m trying to find a way so that this Null1 stays automatically perpendicular to its path. Something like Auto-orient, but this one doesn’t change my Null rotation (so doesn’t effect on my layers expression..)
Hope I made it clear, and thank you so much for the help.

Hello Dan,
thank you for the script, as well as your whole website.

Maybe can someone here help me with my script, in the same spirit of this one?

I’m trying to use this code but then my layer stays transparent, it may have a mistake:
angle = transform.yRotation%360;
minAngle = -23;
maxAngle = 22;
if ([angle < minAngle] || [angle > maxAngle]) 0 else 100

There I want the opacity to go from 0 to 100 without fading. Hope this is understandable enough, or?
Thank you for the help.
