You may notice subtle changes in the overall look of the game, especially when looking toward the sun, with improved light scattering and atmospheric effects. This new system also gives us a stronger foundation for future visual tuning and features.

In addition, sea base and power plant lighting were improved on Tenebris Island. We’ll continue improving location specific lighting in the coming updates.
