Hi Steven!

So I guess I have to elaborate, sorry for my short post the first time...
But really, actually I think the post wasn't too bad, because I think you
did everything right, only that you probably ran into a bug in Moray:

Correct, I forgot to mention that.

I guess you didn't change the density function. It seems that there is a bug
in Moray (I will notify Lutz anyway): The "constant" keyword does not get
exported to POV-Ray. If you define a halo with a density function other than
constant, you get your halo! If you need to use "constant", then it seems
that you have to hand-edit your code after export (I tried that and it
worked).

Hope this helps a little bit more!

Johannes.
