The environment declared the sky as its ambient source without a sky, so
shadowed faces received no ambient light. A procedural underwater sky now
feeds ambient and reflections; the directional light is steeper and
stronger with 70 % soft shadows; SSAO, filmic tonemapping, aerial
perspective and tinted volumetric fog complete the pass.

Lighter fog and volumetric fog, brighter key and ambient light, terrain
tiles visible to 420 m (60 m fade), and a background colour equal to
the fog colour times its energy so culled tiles never read as a dark
band. The seabed shader culls back faces again now that the tiles are
wound front-face up.
