If you want the glass to fall down (vs a zero gravity flyout) you will need some downforce to get the glass to drop. You will need physics on all the glass parts. If you have the free "Attribute Iterator" plug-in from AssociatedFX you can drag select all 75 and apply it in one shot. To get it to break from the middle drop a sphere into the scene and scale it down so that it is small enough to hit just the middle part of the stacked up glass shards. You can hide the sphere during the render or bake the physics onto the glass and delete the sphere ( a good way to speed things up once you have the glass flying the way you want it) The sphere would need an initial velocity in the right direction to get it moving. If you have C5 I have a simple sample file I can put up here. wayne k guam usa
