I’m still working on the world editor.  I’ve made some real strides in the terrain editing functionality.  Now you can save a terrain and it produces a height map that can then be loaded by the world editor.  I’m still trying to work out all the specifics of how to make this work exactly the way I want it to, but I’m sick today and I don’t have the patience to work on it right now, so I’m really just posting a “no update” update.  I guess it’s better than nothing.
