What's New in MEL and Python

PySide now included with Maya

PySide version 1.1.1 is now included with Maya. It is built with Python 2.7 and Maya Qt version 4.8.2.

PySide is a set of Python bindings for Qt that are now shipped with Maya. It is an Open Source project with the same licensing as Qt.

See http://qt-project.org/wiki/PySide for more information regarding PySide.

For sample PySide code, see creaseSetEditor.py in the following path of your Maya installation:

(Windows) \Python\Lib\site-packages\maya\app\general\

(Linux) $MAYA_LOCATION/lib/python2.7/site-packages/PySide

(Mac) Maya.app/Contents/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PySide

New commands

The following commands have been added:

addMetadata
Note
For the addMetadata, editMetadata, getMetadata and hasMetadata commands, the channelType flag (from Extension for Maya 2013) is renamed to channelName in Maya 2014. Although the channelType flag still functions correctly, you are encouraged to switch to the new channelName flag.

Use the scene flag when you want to add metadata to the entire scene as opposed to individual nodes. If you use this flag while having nodes selected, the nodes are ignored and a warning displayed.
