So I have models and want to animate them blowing up. Anyone know if I can seperate vertices so that I can have shards of buildings seperate from the main building?
You can split it into pieces by selecting them in edit mode and pressing P to Part them. Then Keyframe each seperate object (part).
jms has an explode script that will shatter an object into its component faces and give them each an IPO.
these may help you with explosion fires:
