If I remove the density map, will rendering times change? Also, how
should I specify the media's density when the pattern is absent?

You may not need as many samples, whitch will make things go faster.
NEVER use intervals and only use samples. It's MUCH faster.
Set your media base density. The density from the map get multiplied
with it.
scattering{1, rgb 0.01,.....}
Change the rgb value.

I'll try that then.
OT - Too bad we don't have a GasSys include like we have a LightSys one! :)

It's worth a try at least. As for the density, just specify none. All
you use to control the constant density is the parameter after the
"emission", "absorption" or "scattering" keyword.

No such luck.
:(
It still drops render times to the pixels-per-minute range.

Try with less samples. Uniform media usualy need less samples. Don't set
intervals but leave it to default = 1.

Samples right now are at their defaults. Should I use values smaller than 1?

Try samples 5.
A value of zero or negative don't make any sence, and should'nt work.

I'm using the defaults which are 1,1. Can I go lower than that?

samples 1,1 may have been the default for method 1.
The default method 3 only use a single samples value. If there is a
second value present, it's ignored.
samples 1 is the lowest you can go. That mean that you only ever take a
single sample of your media.
