    Hi,

    I am trying to drive a linear wipe transition with the y rotation on another layer. So I have linked them using the pick whip. This works however it animates from 0-100%. I need it to animate from 100-0%. Is there something I can put in the expression to reverse it?

    linear(x, 0, 100, 100, 0);

    Replace x with your pick-whipped property.

    In English, this code says, “as x goes from 0 to 100, return a range from 100 to 0.”
