Week 16: Johnny Jupiter and Space Switching


My friend, Nick Cannon, made some super awesome concepts a while back and I promised him I would sculpt some in 3D. Alas, we have Johnny Jupiter!

Now that Johnny Jupiter has his suit on, we blast away into the land of spaces (pun intended). Chad Vernon came out with a really cool matrix space switcher and matching workflow using the new offsetParentMatrix attribute in Maya and the new blendMatrix node. I grabbed Mr. Vernon's idea and modified it slightly to better match my workflow. The latest version of piper includes my version of space matching/switching through matrices.


The workflow for space switching with piper goes something like this:

1. Add spaces to a transform node by:

import pymel.core as pm
import piper.mayapy.rig.space as space

# select all the spaces you want to assign, 
# and lastly the transform/control that will be driven by these spaces
selected = pm.selected()
space.create(selected[:-1], selected[-1])

2. Then switch between spaces by:

space.switch(selected[-1], selected[0].nodeName() + 'Space')

Where the transform with the space attributes is the first argument, and the space to switch to is the name of the attribute.

Hopefully I'll get a GUI working to simplify the space switching process even more!
