I’d post the .blend, but I didn’t keep it since I was just playing around. 
The basic concept, as Nico showed me is the following:
- Instead of using norm or xyz forces on the emitter to shoot off the particles, use a force field above the emitter to pull on the particles instead.
I think this is really cool for 2 reasons. 1, it helps to focus the particles at a point like fire is apt to do. 2nd, it makes it really easy to animate a gust of wind or what have you by animating the location of the force field.
-
Animating the halo size on the particle texture. This really helps with the tongue lashing effect of the flame.
-
Use a fairly high RandLife setting also helps with the random flame tendrils
-
The rest of the flame settings, I think you’ll find in most blender particle tutorials.
As for the deflector, it’s just a solid mesh with “deflection” turned on. I think I just left it at the default settings, though I may have played around with “dampening” a little bit.
