EDIT: The wiki is working now, so I have removed the tutorial from here. You can find the tutorial at its new home on the wiki:

Yay, I can log in now!
Unfortunately, I seem to have run into another problem. I can't upload any images to the wiki. I've tried several times, using variations on file names to see if it might help. The error looks something like this:
Could not copy file "/tmp/phpC8RHOq" to "/var/wwwroot/spring/w/images/5/59/Rnt1createimage.png".

Someone probably forgot to chmod the image directory with the server move?

Haha, POVray, of course! I can't believe I never thought of that. Here I've been making all my heightmaps by hand in gimp, and POVray's been on my HD the whole time!

Could you use povray to render those huuuuuuge textures needed for smf maps in reasonable time, using an approach similar to sm3?

How long does Pov-ray take to render?

The short answer is yes, depending on your definition of "reasonable". That's going to be the subject of my next tutorial, if I get around to it.
The maps I've rendered so far in POV-Ray take about 20-30 minutes (for a 16 x 16 map). However, the time can go WAY up in a hurry if you do complicated things with your texture. It's also more difficult to achieve L3DT quality textures.
For all of my maps so far, I've use a tiled texture (512x or 1024x) for the flat areas, and the mountains are 100% procedural textures. POV-Ray can layer textures on top of each other and use the slope of your height map to determine which texture to use. Similar to sm3.

I've never used povray, but isn't it all processor-driven? No hardware acceleration, raytraced everything?
Might there be a faster renderer you could use for a faster look at your landscape? Say, for example:

Yes, all processor-driven.
If you're just doing a quick preview of the landscape, such as in my tutorial above, POV-Ray renders extremely quickly. Those 3D images finished in about 2 - 5 seconds on my machine. It would be slower if we were doing complicated things with the texture (reflections, etc...).
