One of the main aspects that we had to overcome was the shatter of the glasses, as we were quite new to maya it took us a while to work out how to use the dynamics. We had to play around abit until we got it how we wanted it. These are the tests we did for the shatter.
as you can see the dynamics need to be changed to make the glass fly apart more, it also needs to be cracked into more peices.
here is a test with the fly, again it is to slow.
Once we got the shatter how we liked it we had to import it into our scene then time it with the fly.
