I am semi-familiar with PFlow but I am stuck now. I am a long time lurker here learning so much information its just rediculous. So visuslizing what I want...a spider web, but one side of the web catches on fire and spreads to the rest of the web. I can think of a few ways to get this using PArray and some animated slice planes, but that wouldn't look as real as the fire spreading throughout the geometry and then dissaprearing. I have tried to use PFlow for this as well, although i can't seem to get a good fire look from PFlow and I can with Parray, although if anyone knows how to achieve a good fire effect with PFlow let me know please. I am using default max 2008 with no plugin's so this is just raw max. Thanks guys and hope to hear from you masters in a bit.

Drive it by a gradient map. Birth at a rate and then only emit on the white points

You can do it with a deflector in PFlow too. Just add a collision test and a moving deflector, to send the particles to a new event in which they spawn and a force is moving them upwards. On a fire with pflow - http://www.allanmckay.com/tut/pflow_fire.avi - a great tut by Allan Mckay.

Render the particles in a separate pass and post composite them back into the scene is one option.

Yes, it will blur the whole scene and will also slow down the rendering... that's why sometimes you have to render the particles in a separate pass as Ian suggested.
