thisLayer & Master Layers
When creating custom controls within an expression you always have an option to select either 'thisLayer' or a 'master' layer.
Understanding thisLayer and Masters
What Is thisLayer?
If you haven't been writing expressions for long you may be unaware that you can reference a layer with a simple line: thisLayer basically means what it says, this layer.
The variable doesn't matter in this situation. However, I like to set layers as targets to easily reference back to them for later.
What Is Master?
A master layer referes to a layer that normally contains effect controlls for properties on other layers. Basically this means you are able to maipulate layers by using the master instead of having to find the layer itself. You can reference a master by doing the following
I like to set master variables inside the expression so I can quickly reference them again if I need to.
