Finally finished this example that's been sitting on my backburner. It's a really simple demonstration of how you can use the Pose Tool and Pose Scopes to get invisible rigs and motion paths in Houdini.
Has anyone used them in production, by chance? What's been your experience?
Caveat: that hip file is definitely NOT an example of good rigging practice, by any means!
