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).
