A very long time ago I used MicroEmacs in MS DOS v6.22. And then I was able to
make MicroEmacs gather the error messages from the console (when compiling) and
show them in a separate window (IIRC). So I guess that it is still possible in
Windows.

In Linux/Unix POV-Ray writes to stderr (and perhaps stdout). You can read more
about redirecting in BASH here:
https://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO-3.html

NB - What is written here:
https://www.povray.org/documentation/3.7.0/r3_2.html
- indicates that one should be able to write something like this:

cat test.pov | povray +I-

I have tested this in BASH with the POV-Ray available in Ubuntu (20.04 ?), but
unfortunately it does not work.
