This plug-in gives animators an easy constraint workflow for picking up and putting down objects. Most useful for character animation but also works for other instances where one object picks up another.
Install Instructions:
1. Install Python! I use Python 2.6 and I don't believe anything higher is supported by Softimage.
2. Drag and Drop the .xsiaddon into the viewport to install. Or use File > Addon > Install
3. Help is available by right clicking on the addon in the Plug-in manager and choosing 'Help'
Works with 7.01 and greater.
