checkbox expression

[Dan Ebberts]

It will depend on the effect, but as an example, you could use this to set a blur amount to 5 while the checkbox is on and set it 0 when the checkbox is off:

if (effect(“Checkbox Control”)(“Checkbox”) == 1) 5 else 0

i Think i can help;)
so first create an adjustment layer in your edit window of your project name it, let`s say “_Fx CTRL” with the checkbox control name it, let`s say “GLOW” after select your comp or layer with your effect press T which brings you the opacity, keep press left ALT on ur keyboard and click on the stop watch now type: value * thisComp.layer("_Fx CTRL").effect("GLOW")("Checkbox");

DONE! I hope is gonna help you! chhers

yes there are many ways to do it and easier with other expression (slider, …), but I wanted to know if for example:

I have a layer with an Effect “Black & White” and I have an “Adjustment Layer” with “Checkbox Control” .
I want when Checkbox is tick “Black & White” else to be off

[Dan Ebberts]

You could add a CC Composite effect below the Black and White effect and use this on its Opacity control:

if (thisComp.layer(“Adjustment Layer 1”).effect(“Checkbox Control”)(“Checkbox”)==1) 0 else 100

Very helpful this 🙂

But this expression only works with properties of one dimension. How works it with a property of two dimensions? I hope you can tell me.

[Dan Ebberts]

Two dimensions would be like this:

if (thisComp.layer(“Adjustment Layer 1”).effect(“Checkbox Control”)(“Checkbox”)==1) [0,0] else [100,100]
