@Dan: I've planned a "Tree-Placer" like in the Sandbox editor, so that you can select different entities an place them on the terrain, randomly in an area.

Almost the whole editor is rewrited. Only some parts of IceX are in IceX2. The terrain system is totally different. now you can have real mesh LOD an the terrain texture is using multitexturing. If you want to import an IceX-level into IceX2 you can not import the terrain texture.
There is no release date yet. I would say till christmas the editor is ready for the betatest. I hope I have cleared all bugs in IceX2 which was in IceX (especially the shadow generating).
The editor will be released with 2 language modules (english and german).
