Yes. In a way.
I couldn't get good results unless the "complementary color" was used along with
scattering, because otherwise it always remained transparent. Which I think is
where the self-shadowing would have been if rendered in v3.7.

method 2 intervals 2 and a sufficiently high samples (50) was best I could find
for it. That's for both scattering and absorption (complementary color) while
leaving light_source color <1,1,1> and extinction 1.0.

Not much luck using method 1, while method 3 just kept over-brightening in the
directly lit outer portions. However, using commenting out intervals or raising
its value above 1 was better than if left at 1.
