I had a little time again for MapBuilder to make some new example levels for next update, featuring exponential shadowmapping (both for shade-c based, and pssm). I prefer the shade-c based solution because it has self shadow support on alpha textures, and a bit faster, thus some thousands of nice grass models can be placed into a scene.
I decided not to wait for engine update, so hopefully in next week it can be out, and will be followed by some usual stuff like little contribution demos, and after bug reports the game script package will be also updated.
