Yes, I'm pretty sure there is a way. I don't have Illustrator on this computer, so I'll have to check when I'm at work tomorrow, but I believe that you need to find a way to "expand appearance" (I think?) of the effect. Look under the Object menu, perhaps?
Heads up: Be mindful of those expanded 3D objects. If you've applied lighting/shading or anything, 'Expand Appearance' will create lots of overlapping shapes to fake the shadows. It can make for a really nasty grouped object.
