Okay, I hope it's safe I'm more looking in how to handpaint stuff myself to avoid those problems. If you want to model more things let me know Thank you for working on this !
c++ for core js for ui and unit ai Json for civs lua for premake python for lobby There is a github branch for pathfinding I dont have the link right now If you are a student you can get a visual studio pro licence else you can go by visual studio express or code blocks. To get the code you will need a git client or a svn client like tortoise svn. Depending also on the platforms you are on. Read the getting started for programmers in the wiki.
@Trinketos, could you provide a link to get all the new models you made ? So we could make the public access them, As far as I know you haven't commited them here : If you need more info on how to this, I will help you.
@Gusseb, could you scale it down when you do so ? I'll add it when it's done. Also, sorry to be a little annoying but are you sure the graphical sources for the textures match the license ? I just want to avoid juridic issues.
