Hi there,

When you downloaded part one it came with two files, CharacterControls.zip and Rigging.zip if you extract the Rigging.zip it contains the partial numbered scene files for the end of each tutorial part. The file you need is Rigging_Leg_01.mb, to get it back to the starting point just select the groups called "Root" and "Ltr_Foot_GRP" in the outliner and hit delete.

Note that the model is set to template in the layer editor so it will appear pink when you select it, he sets this up in the first two minutes of the tutorial so if you watch that it will make sense.

Hope you'll enjoy the tutorial and let us know if you have any problems,
Nilla
