Demo scene

Demo/Scenes/EasyWeatherDemo is a finished scene with terrain, trees, rocks, water and the complete system. Open it from the Quick Start window or the Project window.

The demo folder also holds the three demo weather presets (Demo/Weather Effects), the demo water shader and material (Demo/Water) and URP settings for the demo (Demo/Settings).

Camera controls#

DemoCameraController has two modes, switched with Tab.

Esc frees the cursor, a click captures it again, and the right mouse button looks around while the cursor is free. F1 hides the help text. In first person, deep water turns walking into swimming on the surface; walk out at the shore. The controller works with both the Input System package and the legacy Input Manager.

Test HUD#

DemoWeatherHUD is an on-screen test panel that needs no canvas: add it to any object. It shows the frame rate, one button per weather preset, a time of day slider with speed controls, switches for the cloud layers, cloud shadows, fog and the night sky, and an event log.

The HUD writes straight to the module fields. A value driven by a 24 hour curve is shown disabled, because the curve would overwrite it the next frame.

Demo water#

The KDA_Water shader is part of the demo, not of the weather system, but it shows how a custom shader can follow the sky:

• Its reflection and sun glitter come from the sky globals, so they follow the time of day and the weather. The glitter dims under cloud cover.
• It receives Cloud shadows.
• Looking up from below the surface shows the sky through the water.
• It needs Opaque Texture for refraction and Depth Texture for its depth color.
