OK, I thought about that but was hoping there was a "volumetric lighting" setting or something like that.

So it looks like I have to fake it with a seperate light source. My first thought would be to make an expression that ties the light's intensity property with the flame particle's (blank). Or maybe the tie the light intensity to the average value of the (blank) property of the particles, since there are many particles at play in a fireplace.

I really don't know how to tie the light intensity to the particles. Any suggestions?

Another idea I was playing with was Mental Rays global illumination/final gather. Would I get the right effect if I threw enough photons on the flame particles with a really high intensity setting?

Thanks,

Brian
