Cell Fracture adding unintentional items to object I'm trying to use the Cell Fracture add-on in Cycles Render to shatter a wine glass. The final product had added "blocks" onto the final object.

Does anyone know what could be causing this and how to fix it??

Original:

Shattered Object:
It's because your "wine glass" has no volume in some parts. The brim of the glass is infinitely thin. How can something like that be fractured? 

Try adding some thickness to your model first before doing your spin extrusion (if that's how you made this).
