How To Toggle Layer Visibility With a Checkbox Control in After Effects
Learn how to turn a layer on and off in After Effects using the Checkbox Control.

if you work in a team environment or want to create a template for multiple projects, the Checkbox Control is a handy tool you can add to your AE projects. Unfortunately, many people don’t use Checkbox Controls because they can’t be created without writing an expression, but don’t be intimidated! Once you have a Checkbox Control in place you can quickly turn layers on and off in any comp in your project. The controller is a simple way to turn on/off layers without having to track them down in your compositions.
1. Create a new adjustment layer.

The adjustment layer will simply be a place for the checkboxes to live. It doesn’t really matter what the adjustment layer is called, but you might want to call it something like “Controller” if you are planning on using this technique in a template.
2. Add the effect “Checkbox Control” to the Adjustment Layer.

Simply grab the “Checkbox Control” effect from the Effects panel. It can be found under Expression Controls--- Checkbox Control.
3. Open the opacity of the layer you want to check on and off.

Find the layer that you want to turn on/off with a controller. Select the layer and hit the “t” button on your keyboard. This will call up the Opacity options.
4. Add the expression.
5. Your layer should now turn on and off depending on whether the checkbox is selected.
