Super quick color and time expression
Greetings folks. Something super easy for expressions geniuses…
I have a bunch of layers using a “Change to Color” effect, that goes through several colors. Every layer has a the same effect, but each layer starts at a different time. I want to tie the color changes to a null with a color control, so I can play around with different colors without having to change the effect for each layer.
But how to do I get the various layers to start their operations based on the time of the null layer. So no matter where these other layers are, they actuate based on the beginning of the null layer. I’m sure it’s a simple time expression of some kind.
thanks for any help!

i think you’re looking for something like this:
ctrl = thisComp.layer(“Null 1”); // change this to your control null
ctrl.effect(“Color Control”)(“Color”).valueAtTime(time-inPoint)it will make all color changes relative to the inpoint of the layer itself. it does assume that the color changes on the control null are start at the beginning of the comp. if that’s not the case you could try this:
ctrl = thisComp.layer(“Null 1”);
ctrl.effect(“Color Control”)(“Color”).valueAtTime(time-inPoint-ctrl.inPoint)Kevin Camp
