global effect toggler
Greetings all, wonder if you can help.
I’ve got a comp with about 20 solids with fractal noise, glow and various other stuff applied to them.
Is there a way via expressions to create a checkbox that will switch off specific effects for multiple layers?
So a switch that will let you turn off all the glows for a set of layers for instance. I can’t figure out how to link an effect on/off box to one of those checkbox effect things.
It’s probably very simple but I’m beat.
Cheers!

Aharon’s Expression Controls #2 tutorial (a little farther down the page) will show you exactly how to do this.

Thanks, I watched that tutorial this morning…but it doesn’t seem to tell me how to actually switch an effect off?
It shows you how to link effect propeties or opacity properties to a checkbox but not the effect itself. I just want to be able to literally disable glow effects on 20 layers with a single checkbox. If that’s in the tutorial then I’m not looking right!
Anyone care to help out an expressions simpleton here?

Hmmm… OK – I see.I guess it would depend on the effect. For glow you could set the Glow Intensity parameter to what you want and then apply this expression to that property to link it to your Check Box like this:
if(thisComp.layer(“Null 1”).effect(“Checkbox Control”)(“Checkbox”) == 1) value else 0

okey dokey, yeah that will work fine actually. The intensity of the glow and the opacity of the fractal noise.
Thanks Dan
