The folks at Motion Boutique were kind enough to send me a copy of I’ve been experimenting with mixing the Newton physics engine for After Effects with Trapcode Particular. Although it’s still not a substitute for something like Krakatoa or Fume, there’s some cool possibilities here.
Newton is incredibly easy to use. So far, I’ve not needed any additional reference or tutorials on it. Just pop it open, experiment and you shouldn’t have any problems. The short story is this: create your 2D layers in a comp, access Newton from the composition menu, and solve. Just like any dynamics system, you’ll have to define what objects are dynamic, static, etc.
In this example, I used about 20 null objects, and parented a light to each (this is begging for a script to speed along the process, and I hear Motion Boutique is working on it.) From here, I used these lights as emitter objects and created some basic Particular settings that mimic basic fire.
The biggest shortcoming I’ve found in the process is that Particular forces the user to choose between Bounce and Air Physics. The impact of this is that I can either have my particles affected by turbulence and wind, or I can have particles bounce off surfaces. You’d think the bounce would sell this more, but I opted for the Air physics and some turbulence.
This is just an early test. I plan to fine tune this and develop for a future tutorial.
