I’ve only had the software a couple of weeks, but if you visit the Theater section at ravensblight.com you’ll find two of my short films using PI (one’s a sci-fi and one’s a gun fight). They’ll give you some idea of what can be done with this software. I draw my muzzle flares by hand, but use PI to simulate gun smoke, bullet hits, and squibs.
You can also create explosions, sparks, laser hits, and I noticed a light saber file posted here someplace. I’d suggest trying the free demo if you’re not sure, but i think the software’s amazing! 🙂
