We had a "Mini-Map-Contest" on our Clan (Hyper-Frag.de.vu) beginning of 2006 and this was my entry.
It was aiming at using all space available with
"/newmap 1"
and it does use the whole octree structure. Hence the huge size of the file.
It doesn't use any configuration though ...
It has 3 distinct levels - a basement area, with lots of items, a ground-floor area with some items only and the roof area where you can do some sniping.

This is the first sauerbraten map I am releasing to the public so I'd appreciate some comments.
Also I hope I really fixed everything to the new physics algorithms, since I was building it right before these were implemented :-/

BTW : I am aware there is very little ammo distributed ... it's supposed to be like that, to encourage more strategic play,
... there's always somewhere to run to ;-)

Thanks for the input makkE!
I've added 4 jumppads (one to each gallery walkway) and
another one to the bottom "garden" to reach the "hanging garden" ...

Also I remip-ed the map and relighted it ... I seem to remember I used to get weird lighting errors with lower light precision;
guess that was due to the old sauerbraten not doing lighting as efficently as the current release.
Thanks to this filesize has dwindled down to 1.2 MB (previously 5.3MB) ... thanks again : makkE!

Just need to give a shout out to octree and it's merits here too. Lighting a BSP used to take my old box AGES -
mapping cube/sauerbraten is so much more rewarding since you get releaseable results in just the time it takes to refill your cup ;-)
