This is a follow-up to the last Practical Physics on how to use particles with physics driven props to get ground explosions and starburst explosions. Covers using gravity to control the explosion which leads to a question I received about how to adjust gravity when you have a scene that needs negative gravity for one group and positive or no gravity for another group.

Run the groups independently to bake in the animation based on the current gravity setting then set the gravity for the next set of props and so forth.

Thanks to all for the emails and words of support for this ongoing series of tutes. I appreciate it very much!:cool:
