In any case its great to see that lighting is being actively worked on. There are probably 4 major things i have been looking for in Outerra that would make me happily settle down for the long term while the rest of the engine is tweaked.
Lighting is a biggie since without that, the world is pretty much useless at night.
Clouds because whats the Earth without clouds?
Rivers and lakes for the same reason as the clouds......
The horrible death by fire of the weird green grass!
Any of those arriving would be a huge event for me!
