Has anyone around here figured out a way to make fire look like its coming directly off the ground? Axeman's great tutorial produces awesome fire, but I need fire in a situation where the bottom/fuel of the fire can't be masked out. I need it to be showing.

Any ideas would be appreciated.

are we talking explosions, huge plumes of fire balls? or just fire, burning on the ground?

Cause if its just fire, you could probably pull it off with practical effects. (Depending on were your location is)

It's just fire. I'm using axeman's tutorial, but trying to tone it down a little, so it's not so raging. then set it on a hillside that's not real close to the camera.

You might try starting the particles off completely transparent, and quickly (maybe 3 or 4 frames) ramp them up to your normal transparency setting, to soften the edge between the flames and the fuel.

hmm... not sure I'm understanding (still kinda new to this end of things), but I'll play around with it and see if I can't get it. I know you know what you're talking about, so I've just got to "get on board." I'll let you know if it works.

Heh, well, I'm somewhat familiar with the particle engine, but I'm just kinda throwing ideas out there. I haven't tried that personally, but it seems like it might work.

If you are familiar with the opacity gradient, set a marker at Location 0% to 0% opacity, and then another at 2 or 3% location to 100% opacity.

You might try the Flaming Death v2.0 preset as a starting point, and fiddle with that. It is already closer to what you are after, I think.

If you don't mind bypassing the particle generator entirely, some of these fire-based AlamDV image streams look as though they would be useful for a shot like that, specifically Sollthar's "Burning Ground" ones:
