Sky Integration
Sky Integration mode is designed to increase the realism of volume objects in scenes that have hazy or foggy atmospheres. When Sky Integration mode is active, the sky effects such as haze and fog are taken into account when the volume object is rendered. This helps blend objects realistically into the atmosphere.
This mode is very useful for creating realistic cloud objects or fog objects.

The image below shows two spheres with a cloud texture applied. The sphere on the right has Sky Integration enabled. On these small objects, it's not easy to see the difference, but the sphere on the right shows a slight difference in how it is blended into the sky.
