Cogitatio

Cogitatio is a suite of plugins for Unreal Engine that operate independently of each other, but are capable of empowering each other and exposing new features when present.

Aer

air, climate, atmosphere

Aer is a weather and atmospherics plugin. Originally, night and day cycle functionality was going to be handled in Hora, but weather and atmospherics have such a close relationship with the sun and moon, that it made more sense to move that functionality into Aer. On top of weather, atmospherics, and night/day cycles, other visual (and not-so-visual) elements such as shooting stars are in the works.
