    Hi All,

    I am racking my brain trying to figure this one out…

    I need a specific Layer Marker (marker named “opacity” on lets say layer 1) to switch another layers (layer 2) Opacity off (0%).

    Any help would be great…
    Thanks

    This opacity expression for layer 2 should do the trick:


    try{
    if (time > thisComp.layer(1).marker.key("opacity").time) 0 else value
    }catch(err){
    value
    }
