summerengine

Light a 3D scene: sun, omni and spot lights, WorldEnvironment, sky, shadows and ambient.

Wire music stems to game state: combat, explore, boss and tension crossfades on a shared bus.

Playtest by driving the live game: deterministic launch, frame-stamped probes, scripted or recorded input.
