Parameters Description

Parameters Description

Global Scale
Control the global scale of the cloud shadows.

Cloud Texture
Select the texture representing the cloud pattern that will cast shadows on your scene. This texture will define the shape and appearance of the clouds.

Cloud Scale
Adjust the scale of the cloud texture to control the size and coverage of the cloud shadows in your scene. Larger values result in larger, more spread-out clouds.

Opacity
Control the transparency of the cloud shadows. Higher values make the cloud shadows more opaque and prominent, while lower values make them more subtle.

Density
Set the density of the cloud layer. Higher density values create denser cloud formations.

Smoothness
Adjust the smoothness of the cloud edges. Higher smoothness values result in softer, more diffuse cloud shadows, while lower values create sharper, more defined edges.

Wind Speed
Define the speed at which the clouds appear to move across the sky. This parameter simulates the movement of the cloud layer in your scene.

Wind Rotation
Specify the direction of the wind.

Enable Cloud Morphing
Enable or disable cloud morphing, which adds realistic changes in the cloud pattern over time. This can simulate the dynamic nature of real clouds.

Cloud Morphing Texture
Select a secondary texture to be used for cloud morphing. This texture will influence the transformation and evolution of the cloud pattern over time.

Cloud Morphing Scale
Adjust the scale of the cloud morphing texture to control the magnitude of changes in the cloud pattern. Larger values result in more noticeable variations.

Cloud Morphing Speed
Set the speed at which the cloud morphing occurs. This parameter determines the rate of change in the cloud pattern over time.
