Expression Property Editor


Controls a mathematical expression that drives a parameter value.

For more information about expressions in general, see Animating with Expressions [Animation].

To display: Open the property editor that contains the parameter driven by the expression - the Expression property is available on a tab within it. To open the Expression property editor by itself, make sure that an explorer is set to show animatable parameters, then expand the parameter and click the Expression operator's icon.
