Applying To Properties

Depending on the type of expression you have selected it will change how it's applied to the property or properties.

Selection

Applying To A Single Property

An expression library item that contains a single expression.

This will allow you to apply the selected expression to the selected property regardless of if that expression can be used on that property or not.

An expression library item that contains multiple expressions.

When trying to apply a multiple expression library item to a single property it will check if any of the expressions inside the expression library item match that of the selected property. If any match it will apply them. However, if there is no match it will not apply anything.

Applying To Multiple Properties

An expression library item that contains a single expression.

The selected expression library item will be applied to every single one of the selected properties. Regardless of if that expression can be used on that property or not

An expression library item that contains multiple expressions.

When trying to apply a multiple expression library item to multiple properties it will check if any of the expressions inside the expression library item match that of the selected properties. If any match it will apply them. However, if there is no match it will not apply anything.

Applying a single expression to either a property or properties can result in expression errors as you may apply an expression built for the position property to the scale property and will get an error that the expression is a value of 2 instead of 1.
