lighting up layers through a slider?
I’m not sure how I’d do this:
I’d like a slider that, depending on what number it is set at, causes individual layers in the comp to “light up” (full opacity). So if it is at 1 then layer 1 is at 100% opacity, if it is at 2 then layer 2 is at 100% opacity and layer 1 is at 0%. Is this possible?

use this expression for the opacity:
selectedIndex = Math.floor(thisComp.layer(“Contorl”).effect(“Slider Control”)(1));
selectedIndex == index ? 100 : 0Xinlai Ni
