The online building is working. That means that NPC's can build buildings during gameplay (for testing proposes the barack was built into the air!):
The start:

In the middle:

Only the roof and the furniture is missing (still need to implement this):

C Mod Interface: We also exposed all Lua Plugin functions via a C interface. So it is possible to make plugins via C++.
Smooth Far Landscape Renderer: I also improved the far landscape renderer to support smooth surfaces and plants and trees. Here is a non (!) voxel example of a landscape:


Now I only need to finish the new trees so that they can be send to the rendering system.
Support for High Resolution Textures on Intel Graphics Cards: A low resolution texture is loaded if now hardware support is detected. But it still looks good because of the detail map!
Archive Support: That was only some fun thing. I found a good library which can read zip/7zip files. Now I can put all game files into one archive.
And I also changed the grass rendering so that small dirt blocks are not visible any more.
