Supervariable

[Dan Ebberts]

There aren’t global variables, but there are ususally ways to work around that limitation. What are you trying to do?

[Jose Sancho]

I want to control a variable that I use in several comps.

[Jose Sancho]

I make a comp with a slider in a null. I just access to the slider through the pickweel and then reuse the code where I need it.

Thanks for your interest Dan.

Use a slider and pick whip to that from other expressions. Just keyframe it if you need set values.
You can add an expression to the slider if the value needs to be calculated.
But! The “variable” is read-only, you can’t set it or alter it via calculations in another expression.
