UDS astronomical simulation

UDS can position the sun, moon, and stars using real-world coordinates and dates instead of the simple yaw/pitch/offset settings. Three independent toggles + a location/date block + an OS-clock sync. All settings live in the Simulation category.

Toggle Overrides Notes
Simulate Real Sun Sun Yaw / Pitch / Vertical Offset Manually Position Sun Target still takes priority
Simulate Real Moon Moon Yaw / Pitch / Vertical Offset / Moon Phase Phase is driven by simulated date
Simulate Real Stars Default tiling stars texture → 360° star map Both textures exposed in Stars category

When to use this skill

  • Need sunrise/sunset times accurate for a real location and date.
  • Setting the sky for a specific city — Tokyo at noon on Aug 3rd, etc.
  • Star positions matching real constellations.
  • Moon phases matching a real date.
  • Time of Day should reflect the player's actual wall-clock time.
  • Defining what "north" means in the level (level rotation vs world rotation).
