Want to set a mood for your adventure map? Want to change your world to eternal day? Want the sky to magically glow? If you want any of these, ATMO is for you! ATMO is an atmosphere generator, meant to set a mood in your adventure maps, as well as control weather and day/night cycles. This current build of ATMO feature selection between eternal day, night, rain, thunder and clear weather as well as special effects such as glowing skies and sped up time. It is very simple to use and is quite effective. It is easy to upgrade, so if you want any new weather effects, custom timesets or faster/slower day/night cycles, feel free to post it in the comments. I'll try my best to add them to ATMO in it's future updates.
