Applying a Glow to a bunch of layer and using a slider to control the random
Hello, I recently asked a question like this and I got some excellent help but I’m stuck on something. I have this expression:
n=thisComp.layer(“Glow Null”).effect(“Glow Slider”)(“Slider”);
n*indexApplied to a layers “glow intensity” and the slider controls the glow intensity but how do I apply this to each layer, yet have each layers glow intensity random based on the slider?

Try posting in the After Effects Expressions forum. Dan Ebberts can point you in the right direction.

I am not sure what exactly you are trying to do, but you can achieve the effect I think you are after by applying a slider control to an Adjustment layer, then apply a wiggle expression to the glow intensity and pick wip the amount to the slider control. You can then use a random number generator on the slider control or manually adjust it. simply copy and paste the glow layer with the expression to the other layers.
Not sure what you were after, but I hope this helps.

The code in my original post I have applied to (2) test layers. I have a slider which is controlling the glow intensity for those (2) layers, now my goal is have the slider control the random glow intensity. So for example, say you have 10 layers and you want each layer to glow randomly without the use of keyframes, a expression is applied to each layer and all I have to do is keyframe the slider and all the layers would randomly glow on and off via the glow intensity property.
