  How to set range

  Posted by Tom Hilfiger on January 12, 2020 at 4:27 pm

  Hello! Does anybody can help me with the problem of setting range?

  For example, if “Y Rot” value of slider control layer falls into the range from 1 to 10 then opacity of another layer should be set to 100%. Otherwise it should be 0%.
  Thanks!

  You need to put the expression in opacity and link it to the slider. Something like this, although you should pickwhip the slider into the expression

  var mySlider = thisComp.layer("Control Layer").effect("Y Rot")("Slider");//here you should pickwhip your slider

  (mySlider>=1 && mySlider <=10) ? 100 : 0;
