    Hi guys, how can I animate and increase the amount of text on a path? I can animate the shape and size of the path but not the amount of text inside it. Please find attached a video example of what I would like to do. Thank you very much in advance for your help

    Hey,

    add a slider to your Text Layer,

    the give the sourceText this expression:

    numChars = Math.floor(effect("Slider Control")("Slider").value);
    value.substr(0,numChars)+"\u200b";

    The slider now controls how many characters are visible.

    Adding the +”\u200b” (unicode character #200B = a zero width space), this makes the start and end characters line up with the same spacing as all the other characters along the path do.

    If you omit this, they will hug each other without any spacing.
