CTF SDK v1.0
This download contains instructions on how to make dual textured CTF maps (so that you can have red and blue bases), the shapes file to use with Forge, and a texturing script. To make a good CTF map, you almost have to make distinct Red and Blue bases so that players don't get confused. If you plan on making CTF maps, this download will help you out a lot.
Because using Chisel isn't real easy, I have decided to put this SDK together to make it easier for people to create CTF maps. The readme explains everything you need to know for creating maps with lava and water textures.
The file is a .sit file, so that the filetypes are remain correct. This download does not include Forge or Chisel. The link to Chisel can be found in the readme included.
Good luck mapping!
