JC, I wasn't trying to show off or anything just trying to show that it was possable to get the glass to look broken in B5. I thought of something I did to make it happen that I didn't mention. after making sure I intersected properly (front and side views) and that I had my booleans goung on, instead of selecting the group and the rock I selected the group by clicking on it them held down ctrl and selected the rock. I don't know that it makes a difference but you could try that too. cheers, - TJ
