Layer markers trigger alternating scale values with easing.
Hello all,
Let’s say the layer has a ‘natural’ value of 100%
at the first layer marker this value jumps up to 150% over 5 frames (easy eased)
at the second layer marker the value returns back to its natural value of 100% (again, over 5 frames eased)
at the third layer marker the value jumps to 150% (over 5 frames eased)and so on…
I’ve seen a few useful expressions that use layer markers to trigger changes in value, but haven’t found anything that alternates between the original value and one generated by an expression.
Thanks in advance for your help.
Wal.

Something like this probably:
easeTime = framesToTime(5);
n = 0;
m = marker;
if (m.numKeys > 0){
n = m.nearestKey(time).index;
if (m.key(n).time > time)n--;
}
if (n > 0){
t = time - m.key(n).time;
if (n%2){
ease(t,0,easeTime,value,[150,150]);
}else{
ease(t,0,easeTime,[150,150],value);
}
}else
value
