Ok.... so, since i've spent an hour or so messing with this..... thought i'd share my findings......

I'm using mandriva 2024 FWIW.........

installing povray (as root ...)
Code:

urpmi povray-common
urpmi povray-official
urpmi povray-pvm


This installs povray.....
some samples are included HERE:
Code:

cd /usr/lib/povray31/scenes/advanced


To run the samples..... i had to be root .... as my user didn't have permission to execute in that directory.....however any povray scripts in my users home directory ran just fine as a normal user.

so...... as root.......
Code:

[root@localhost advanced]# x-povray -i chess2.pov

produces this in the terminal window.........
Code:

Renderers like POV-Ray, Mental Ray, and Brazil R/S are absolutely wonderful, but the fundamental flaw that most people overlook with all rendering is textures. If you guys want to do some great looking renders, pickup a program like deep paint for UV mapping and the like, thats where the real meat is.

I think you'd be better off with Blender. Unforunately last time I used blender they didn't have a native global illumination engine, and you had to use radiosity to fake it. Man I wish they'd incorporate mental ray into their system....mmmmm mental ray. ^_^
