I want to make a round space command deck with lighted windows. I
am using Moray 3.2 and POV 3.1g. So I thought "Just make a hollow
sphere, put a point light inside, and cut out some cubic
windows." That didn't work. How can I do this? Here's my POV
file.

Using the keyword "hollow" does not make a sphere hollow. That keyword
is only there to allow media and fog to be used inside of an object.
To truly make the object hollow you will need to difference out
another sphere from the first.

I assume you're talking about a typical space scene, camera outside, you
want to see the decks marked by rows of cool little brightly-lit windows.

Try making flat little boxes with a high ambient setting and white color.
They will render bright-white regardless of how much light hits them. Also
this way you don't end up with hundreds of light sources so it should render
pretty fast.

  On a similar note, if the command deck is round like the Discovery
spacecraft from "2001: A Space Odyssey", you can use a white sphere with
high ambient that is scaled slightly smaller than the outside of the
command deck. This eliminates the need to make individual bright pieces
that fit each window opening.

A different way that I've used with some success is to create a window grid
texture.  This is a texture where a color map is used to create lit and
unlit parts.  Using a variable pattern scaled up, you can even get that
light and dark windows effect.

If you want to see an example of this, you can check out my recently posted
animation of a space ship.  Only certain parts of the object used this
texture, and the texture was specially modified to allow the windows to
close.

I do not recommend cutting many many holes in your ship, though.  I've found
that lots of differencing can slow things down a great deal.
