We’re still doing research into the possibility of weather. We would like to do it, but it’s extremely expensive at the moment ( realtime lighting / shadows ).
At some point I’d like to look into some optimizations ( lightmap fading, screenspace post-processing ) that might make this idea more viable.
The problem with making it an option right now is that we’d have to ship two versions of the lobby map, one with baked lighting ( performant ) and one with dynamic lighting.
