particleIllusion has a 2D workspace (like a paint program), not a 3D workspace (like a 3D app). There is no “camera” that you can move, zoom, etc.
One suggestion that I can make for your live-action project: make the particle effects move FAST. The best fire effect will look goofy if it slowly shoots out of your son’s hands. Also, when you shoot the video, make sure you move in reaction to the “stuff” hitting you. Finally, you’ll probably want to do the final particles render with the background video turned off, save with an alpha channel, then composite in Vegas (instead of letting pIllusion do the composite).
I hope others will add tips too.
Alan.
