Hello, I know it is a very old tread but maybe it could help some body. Just select the object and go to: Edit/Delete By Type/History before applying the Shatter. If you try to apply the shatter without deleting by type history you will get this error: {An error occurred while running the Crack Shatter script. Results may be invalid. If necessary, undo to restore the previous situation.} And the shatter will not be successful. Regards.
