– Sun: assign the main directional light from your scene. The rotation of the directional light is used to compute the day/nighttime. Also check the Ambient Light setting for additional lighting.
– Camera Layer Mask: let you specify which cameras can render the effect. For example, if you have multiple cameras and you don’t want one camera to render the clouds, just assign that camera to a specific layer and exclude it from this setting.
– Profile: the profile is where all appearance settings are stored. The first time you add the Cloud Shadows manager, the inspector will let you create a new profile. Profiles are scriptable objects (assets) which can be assigned by dragging & drop into this field, duplicated or deleted from the Project inspector.
– Show Clouds: shows or hides the cloud layer. Note: the cloud layer is designed to be very performant and be viewed from a top-down perspective. It’s not a volumetric effect.
– Coverage: density of clouds over the sky. A value of 1 will fill the entire sky with clouds.
– Thickness: visually simulates a thicker cloud.
– Opacity: uniform transparency for the cloud layer.
– Sun Color: the color used to illuminate the clouds (usually matches the Sun color but you can change it here).
– Light/High Density Color: you can specify up to two colors for the clouds which are picked depending on the density.
– Light Intensity: the intensity of the lighting affecting the clouds.
– Anisotropy: the Sun will shine brighter when viewed from the ground through the clouds.
– Ambient Light: intensity of the ambient light which is added to the clouds lighting.
– Show Shadows: shows or hides the cloud shadows on the ground.
– Coverage: similar to the clouds coverage setting. Usually this value should be same than the clouds section but you can increase it to obtain a more dramatic effect.
– Opacity / Tint Color: customize the transparency and color of the shadows.
– Top Down Only: enable this option to improve performance if the effect will only be viewed from a top-down perspective. If this option is disabled, the screen space normal is calculated to avoid cloud shadows appear on ceilings.
– Altitude: the altitude of the cloud layer in meters.
– Scale: scaling factor for the clouds.
– Offset: shifts the cloud textures sampling by an amount.
– Distance Fade: fades out both the clouds and shadows over the distance.
– Contrast: increase to make cloud borders sharper.
– Edge Noise: increase to produce “wispy” borders.
– Wind Speed: the displacement speed. The y coordinate is not used.
– Clouds Textures: you can change the default textures used by the asset. Additional textures can be found inside the demos folder. The cloud texture 2 is used to add the details for the clouds. The bump map texture is used to simulate a bit of relief.
