Parameters Reference

All appearance settings are stored in the CloudShadowsProfile ScriptableObject. Select the profile asset or expand it in the Cloud Shadows inspector to edit these values.

Clouds

Parameter	Type	Description
Show Clouds	bool	Show or hide the cloud layer. The cloud layer is designed for top-down viewing and is not volumetric.
Coverage	float 0–1	Density of clouds. A value of 1 fills the entire sky.
Thickness	float	Visually simulates a thicker cloud appearance.
Opacity	float 0–1	Uniform transparency of the cloud layer.
Sun Color	Color	Color used to illuminate the clouds (usually matches your directional light).
Light / High Density Color	Color	Two colors blended based on local cloud density.
Light Intensity	float	Intensity of lighting applied to clouds.
Anisotropy	float	Makes the sun appear brighter when viewed through the clouds from below.
Ambient Light	float	Constant ambient light added to cloud lighting.

Shadows

Parameter	Type	Description
Show Shadows	bool	Show or hide cloud shadows on the ground.
Coverage	float 0–1	Shadow density. Usually matches the Clouds coverage, but can be increased for a more dramatic look.
Opacity	float 0–2	Shadow transparency. Values above 1 darken the shadows further.
Tint Color	Color	Tints the shadow overlay color.
Top Down Only	bool	Improves performance by skipping screen-space normal calculation. Enable if the camera always looks downward. When disabled, the effect avoids projecting shadows on ceilings.

General

Parameter	Type	Description
Altitude	float	Height of the cloud layer in meters.
Scale	float	Scaling factor for cloud textures.
Offset	Vector2	Shifts the cloud texture sampling position.
Distance Fade	float	Fades clouds and shadows over distance from the camera.
Contrast	float 0–10	Increase to sharpen cloud borders.
Edge Noise	float 0–1	Adds wispy, irregular borders to clouds.
Wind Speed	Vector3	Cloud movement speed (Y component is unused).
Cloud Textures	Texture2D	Primary cloud texture and detail texture. Additional textures are available in the `Demo` folder.
Bump Map	Texture2D	Normal map used to simulate cloud relief.

Tip: All these properties can be modified at runtime via C#. See the Scripting page for details.
