The Ember Rift's arch at 11:12 on Graphics: Smooth, the setting every new visitor starts on: unchanged from before.
The same view on Graphics: Epic: ultra max, Rock and sky light, 1.5x resolution, bloom round the lava and the heat shimmer over it.
The arch at 20:36 on Smooth: the walls lit evenly by the night sky.
The same night on Epic: the walls take the moonlit sky's colour, the cracks glow and bloom, and the stone round them warms orange.
Rock on at night without lava light: the lava glows, the stone beside it stays cold.
Lava light on: each vertex's nearness to the law's cracks, baked in the workers, lights the rock orange within 22 cells, strongest at dusk and night.
Close to a lava wall, before: the lava's flicker was read across the ground, so on a vertical face it smeared into diagonal stripes.
Lava on walls on: the flicker is read along the wall and up it, drawn out downward, so the lava runs down the face. The basalt columns beside it are unchanged.
