Animate opacity using data in text file
I’m trying to write a simple expression to animate the opacity (on/off) of a solid
according to data in a text file. The text file simply contains one line for each frame and will
specify if solid should be on/off.Can anyone help me out? thanks for any help you could give.

Why don’t you just copy the variables to a text layer and use that layer’s sourceText for your expression?

Can you give me any insight on writing that expression?
Either way, thanks for replying! 🙂

Here’s an example:
Pick-whip your solid layer’s opacity to the text layer’s Source Text property to change *thisComp.layer(“source”).text.sourceText*values = thisComp.layer("source").text.sourceText.split("\r");
f = timeToFrames(time);
if( f < values.length) values[f]; else 0; -
