Added a block of buildings in the background. Also added windows, doors  
and grass.

I keep running out of memory so I made less grass than I wanted to. I'm  
considering converting the walls to a heightfield, but only when the  
building is 100% right. Maybe now is the time to start.

Comments and critique will be appreciated.

Grimly beautiful indeed.

You could use heightfields for the wall sections farther from the camera. 
That might already make a difference.

Looking better and better!

It doesn't look like a particularly memory-hungry scene... what is it that's
using most of the memory? I would have thought that a heightfield wall would
take far more memory than the equivalent mesh bricks.

Debugging memory usage in POV-Ray scenes is a little-mentioned but very
important task! Turn off media and radiosity and see what the scene uses (render
small with no aa for a quick answer). If it's still eating loads, try
commenting-out elements of the scene and render again to see how the usage
changes. You won't need hi-res bricks unless you intend rendering a huge final
version; in fact, they should be one of the smallest scene elements (memory and
speed were the main motivations for my mesh macros). Lower mesh (and heightfield
- same thing!) resolutions until they're on the threshold of the quality you're
happy with. Make simple low-detail versions for distant objects. Can you get
away with clever normals instead of meshes/isosurfaces?

Hope this helps :)

The close brick wall consists of a mixture of isosurface, high and low  
poly mesh bricks. Further away are low poly mesh bricks.

Thanks. I'll take a look and see. I'll give the normals a try.

This is a really neat image. I think the cyan color at the far end of the alley
creates a surreal effect. For that reason it kind of reminds me of a "Twilight
Zone" scene.

I really love those bricks!

Thanks. That's what I was going for :)

Thanks :)

I'll put the macro on the Pov Object Collection when I've fixed it up  
nicely.

I've never looked at the size of my include files before. It turns out my  
mesh bricks were 9Mb each. 6 of them. I'll just have to use lower poly  
bricks...
