Using rigify, Automatic weights parenting fails I'm doing a basic human rig for practice. All of my bones are set up and the rig generates just fine, however, when I try to parent to the rig with auto weights, a majority of my mesh disappears (See pictures) 

Any ideas on what's happening?
To make Rigify work properly you need to enable running python scripts or scripted expressions. When opening your file click on Reload Trusted button on the top of blender screen.
