Opacity Expression Based on first Position Keyframe
Hi All!
I imported a scene from maya with a bunch of nulls, and the position keyframes start at different times, they were particles so the visibility keyframe did not translate with the nulls. Is there an expression to tell the layer to turn on once it lands on the first position keyframe? I also want them to stay on indefinitely tough.
I appreciate your help!
Best,
Aldo.

Like this maybe:
if (position.numKeys > 0){
if (time < position.key(1).time) 0 else 100;
}else
value
