There are not meny resources for files you need to make maps
here are the KVX's that are needed for the most basic of map making, but it is more then a swamp tree, there are 2 Minecraft Trees I made build structure platforms some letters Flooring, a smashed building, mostly small things, some larger ones also, I made every thing and am cleaning out the old stuff to make new stuff. I hope this can help some more prople get into good map making.
