Bummer.

The hills were easy to make; use a heightfield!

I have used heightfields several times, but I can never get them to look
exactly as I want them too.  I wanted hills that really looked like the CS
hills in this case.

My hills weren't really like the classic space ones, but you could
fine-tune them to perfection.

That's the hard part.  And creating heightfield images is quite difficult,
especially when you know exactly what you want.  For some reason, I also
tend to get randomly scattered, small, unsmooth triangles in my heightfields
too, which really ruin the effect because they get shaded much darker.

Tip: If you are just going to use the hills as a backdrop, use a plane
first, as the main "floor" for the models, then add the heightfield,
scale it so you can't see the edges of it, and translate it to a
position behind your model. Then, you make a union {} of the plane and
heightfield, and add the same texture to them. (I used "Goldenrod"
colour with a bump normal, scaled down pretty much to look like sand)

This is basically what I did for the first render, but then I redid the
hills in PhotoPaint since I didn't like the way they turned out.  For some
reason, the way I orient my light sources always ends shading the hills very
different from the plane, so I get ugly edges where the hills intersect the
plane.

If you wish, you can then add focal blur to the camera, to make the
hills a bit blurry. (I don't know how to use focal blur, though)

I think I've tried to use focal blur once or twice, but it takes a whole lot
more rendering time...
