Query: #1 Max Particle Book on the Market

If you want to know how to use 3ds Max's Particle Flow...this is the book you should buy. One word of caution...make sure you brush up on your PFlow basics before digging in. The book definitely assumes that you know what you're doing when wiring up PFlow's Operators and Tests. There's screen shots to help you along, start and completed scene files, and a real nice handful of cool effects covered. More for the Intermediate and Advanced user.
