UDW spatial weather
The systems that make weather happen somewhere specific rather than globally. WOVs and Radial Storms drive state per location; the Weather Mask system excludes material effects from interiors and under-roof areas.
| System | Shape | Visible from outside? | Use for |
|---|---|---|---|
| Weather Override Volume | Arbitrary spline | No | Region-specific weather state, with arbitrary shape |
| Radial Storm | Circle | Yes (clouds, fog, obscured lightning) — requires Volumetric Clouds Sky Mode | A storm seen approaching from a distance; moving storms |
| Weather Above Volumetric Clouds | Above cloud layer | Implicit | Auto-adjusting weather state when the player flies above the cloud layer |
| Weather Mask Brush | Simple shape or painted texture, projected straight down | No | Mask material effects (snow/wetness) in interiors |
| Weather Mask Projection Box | Box-bounded capture of meshes inside, projected down | No | Mask material effects under structures (roofs) |
When to use this skill
- Different weather in different parts of one level.
- A storm the player can see coming in from across the map.
- A storm that moves linearly across the level over time.
- Adjusting weather behavior when the camera goes above the cloud layer.
- Keeping snow accumulating inside a building, or wetness off the floor under a roof.
