Corona clouds are available in Chaos Corona 9 and newer. Adding such elements as clouds to your scene has never been easier. Simply add a Corona Sky and Sun object to your scene and in the Sky object, click on the Clouds tab and select ''Enable''. Within seconds, your scene has now been populated with our graceful clouds!
Corona clouds allows you to control the cloud coverage in the following ways:
Clouds
Note: Overriding the Sun's color directly will now affect the color of the clouds respectively.
Corona clouds work in conjunction with our Sky/Sun object. It's the same Sky/Sun object that you're used to in the past, just with the added power of clouds! So as you change the rotation or angle of the sun's positioning, the appropriate light will also be represented in the clouds. An example of such can be seen below as the sun's position has been lowered dramatically. They can even be added to the LightMix panel for further post-processing!

Corona clouds can also cast shadows onto your scene by toggling this feature on or off from within the Corona Sun settings. By default, shadows are enabled when adding a Corona sun object into your scene.

Corona clouds can be randomized by using the seed function allowing up many different combinations. This setting can be found in the Clouds tab as shown below:
Contrails
Another feature added to the Corona Clouds is the Contrails. By default, these are switched off and can be enabled from within the cloud settings.
