Thanks Mike, if I may annoy you or anyone else with another question regarding blend shapes.

I am following the tutorial you did. I duplicated my head and created a few different facial expressions on a series of duplicates, deleting history and freezing transformations on the way. I deleted the history on each one when i was done, froze the things, selected them shift selected the original and went to deform create blend shape. I opened up the editor and all the blend shapes show up fine.

However when I move the slider the original head shifts to the right to where the blend shape copies are, gaining the expression of the blend shape as it goes. This does not seem to be the desired result as my head ends up on the other side of the screen. I have tried doing it again and I get the same result - any idea what I am doing wrong?
