Hi,
I think I know what you are aiming for, I really don't know an easy way for doing this, but I'll tell you how I did it for an animation. You can find the video segment in my demo reel 07 @
http://www.fxtudio.com/reel07.html The animation is the one that has kind of a teddy bear logo with the words "BIMBO"
I took my object, in this case the extruded logo. I made it editable and made some knife cuts in the desired pieces, most of them cubes or tetris like. then came the tedious part of selecting the two corresponding faces (front and back), then Choose "disconnect" from the functions menu and then "split" from the same menu. This leaves you with your original object and a new polygon object which consisted of the two faces. Then using stitch and sew, bridge tool, create polygon tool, close polygon tool or your method of choice I proceeded to link the two faces, there fore creating individual objects. Now repeat that process for every object. Believe me it is time consuming and repetitive. After that you finish with lots of individual objects that can be animated and are able to do what you please.
I hope this is useful, this is the approach I took and maybe it's not the best one but it works, other than that maybe TP but not sure...
Regards,
Alejandro
