Description

Returns a Boolean of whether or not a module with a name that matches the specified string value exists in the scene.

The exists command is used to query the scene for the existence of a given module or module type. For instance, you may be writing an automatic editing script and are trying to determine whether or not a certain marker, like LUPA (left upper arm) exists or not, in order to determine what method to used for filling in gaps on other arm related markers.
