Underwater window

Seen from under the water, the game's surface is a bright window of sky straight overhead, the depths mirrored in it everywhere past the window's edge, and every surface under the water, not only the ground, shimmers with caustics.

Why deferred: Windrise's lake is shallow and nothing leads the camera under it. The fog already turns to the water's own under the surface, which carries most of the look, and the window needs its own shading path for the surface's underside.

Revisit when: the Fontaine region is built, whose explorable depths make the world under the surface a place rather than a moment.
