The Galaxy Editor is not out yet however it is still possible to start working on maps. I will show you different projects that have already been started by the Mapster community.
Terrain Editor by hyarion and Grum
Grum has been working hard to crack down the terrain format and hyarion made a convenient tool to show and edit it! This is actually an Alpha but it looks very sweet.
3D Model by Kanaru
Kanaru just made two new models. It's still early but that's a nice start. If you too are doing some 3D or 2D artworks, just post on the forums and will get coverage :)
Fan Sites
I am looking forward making a listing of all community fan sites working on mapping. There are many great things done all over the net and I would like to feature them all. I've made a compilation of them but it's far from complete. If you know more please feel free to complete that list on the comments.
