Well, I would start with the "spherical" pattern... ;-)
An attempt at translating is below. (Note: I never did much with halo,
and have no way to check to see how similar the media is, so this is
just a guideline for the syntax.)
media {
emission color White
method 3// Use this if using MegaPOV, if not,
// remove this and use more intervals.
intervals 1// using 2 or 3 may help, I almost always use 1, but
// the official version requires much more.
samples 20, 20
density {spherical// ramp_wave and frequency 1 are default
turbulence <0.3,1,0.3>*1.2 lambda 2
scale 0.4
color_map {// media ignores transmit and filter and uses the
// brightness of the color to determine density
// use the color for "emission" to specify the overall
// density
[0.0 color rgb < 0, 0, 0>]
[0.5 color rgb < 1.75, 1, 0>]
[1.0 color rgb <-2,-2, 0>]// I don't know what was intended
// with the negative transmit...
}
}
}
