Change opacity of every other frame?

[Dan Ebberts]

Something like this, probably:

opacityEven = 50;
opacityOdd = 100;
f = timeToFrames();
if (f%2 == 0) opacityEven else opacityOdd

doesn’t seem to work. I am testing it with a black solid over a red solid. I clock opacity, then alt click to add the expression. it shows the opacity at the points as either 0 or 100, but the actual black solid does not go to 0% opacity?

So you edited the expression to look like this, correct?

opacityEven = 0;
opacityOdd = 100;
f = timeToFrames();
if (f%2 == 0) opacityEven else opacityOdd

Are you saying that as you step through the frames the opacity says it’s changing between 0 and 100, but it really isn’t?
