At last I have started to mess around with fractures. In the following video I broke up a wall using Blender's new in built Fracture tool. After fracturing the object (crashing the computer lots) I shot a ball through it making the shattering effect. I am currently working on a solar system projects using the fracture tools. This will have all the planet exploding from a collsion of a Sun. Currently it is the biggest Blender file I have ever worked with, it is currently 767mb in size with only 1500 objects. Using this new project I have for the first time crashed the Windows 7 desktop. (ha ha, program called windows explorer) Anyway here is the video.
