One of the first things I'll do is add more cameras so they aren't quite so extremely zoomed in.
It's actually me who works on this map, in fact Eric originally built this some years back with some distant scenery to make it look nicer, but then got diverted onto all the new graphics stuff before it was finished. Recently I resurrected an old LFS track editor so I could actually save a track that can still be loaded in the public version.
I removed distant scenery as there were problems trying to draw things so far away. And I added the long fences.
I wonder if the configuration system could be used for something useful. I'm not sure we need both wide grid and long grid? Or are they of some use? You can place your own start positions anyway.
I'm pretty busy on other things though. I don't know how easy it would be to allow a configuration to perhaps turn one of the 1km squares into a dirt arena. I could try to copy one or two of Eric's methods and textures and see how it looks.
What would be the purpose of being walled in to a 1km square? As Degats suggests, can't you just use an existing square? Or would it be particularly useful to use the walls as a boundary? Other questions, if I could do a dirt square, would only 1km by 1km be enough? I'm trying to limit both the workload and number of configurations, so rather not do more than is needed.
