However, the last joint in the chain isn’t auto-oriented: A joint’s auto-orientation is based on the vector between it, and its child. SetAttr ($x + ".I have this pet peeve: Whenever I create joint hierarchies in Maya, it will automatically setup the joint orientation value for you (based on option set in the ‘Joint Tool’ tool settings).

PyMEL node classes now include hundreds of new methods derived from the API, but with the same intuitive and unified design as before. It doesn't matter what name you use to access an attribute: > cam.t = cam.translate > cam, shape = camera()Ĭomparing attributes is just as easy. Keep in mind that the changes could have just as easily been performed by the user interacting with objects through the GUI. And what's more, if anything causes the name of your object to change it will automatically be reflected in your python object.īelow, we make a camera, rename it, and then group and instance it, to demonstrate how the name changes are constantly reflected. This means that the annoying inconsistencies of string comparisons are over: no more worrying about short names versus long names, DAG paths, unique paths, instance paths. PyMEL harnesses the API to create a name-independent representation of your object. The node and attribute classes have been rewritten from the ground up to use the python API as their foundation, increasing the speed and fidelity of PyMEL's object-oriented design. PyMEL 0.9 is a dramatic leap forward in the evolution of python in Maya.
