Synopsis

requires( string string )

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

requires is undoable, NOT queryable, and NOT editable.

This command is used during file I/O to specify the requirements needed to load the given file. It defines what file format version was used to write the file, or what plug-ins are required to load the scene. The first string names a product (either "maya", or a plug-in name) The second string gives the version. This command is only useful during file I/O, so users should not have any need to use this command themselves.
