Spend the weekend on working with the general atmosphere.
We now have dynamic day and night with sun, moon and skygradient. Bloom shader was added which just gives total pizza during sunset and day (the parameters might need slight tweaking to avoid overbrightness). The directional light switches correctly without a seam from sun to moonlight thanks to 1D - lookup textures.
Also did preliminary saving and loading for trees so I don't need to place them each time. Have to create some lowpoly trees some day, but it will require some sort of LOD-system so let's go with the x-planes for now...
The overall feeling of the scene seen in realtime is really good currently so I did a quick export of one of our models to the engine. The model has poor unwrap (made automatically) which shows some blurring and streching, along with over large texture. But now that I see it in the game it doesn't need much more, just good unwrap and some precalculated ambient occlusion, so the bottom of the roof and floor won't receive as much light.
Now lets add the cloud layer.
