Thanks!

However I am far from being satisfied. I encounter issues with radiosity and
media (camera inside or outside the container, you can play with LAYERx_H
parameters, lower or higher than camera height). In the absolute, POV-Ray lacks
specialized density functions that fit into a spherical shell.

Besides, real atmosphere is a very complex thing, not easy to model, and real
clouds are also quite complex and there are many kinds of them, each one having
a specific behaviour with light.

I also cannot figure out whether and how spectral rendering could help.

PS: I could get the POV-Ray code into VS Community and have my own build! For my
first steps inside, I implemented the f_shell_exp() function I was talking about
earlier (==> one more entry in functions.inc).
