Hi,
{Clouds lighting now depends on the sun color intensity and direct input color settings (if selected in the sun properties)}
This feature was implemented in V10 Daily build. You can see how it works in this video: Dropbox
You can download the daily build from here: https://forum.corona-renderer.com/ Chaos Corona 10 for 3ds Max - Daily Builds Changelog
Note: The daily builds are the newest, experimental versions of Corona Renderer, intended mainly for testing purposes and to showcase the recently added features. They contain the latest bug fixes but are not guaranteed to be stable and, in some cases, can even damage scene files.
