Hi, I think there is problem when using multiple CoronaSky maps in CoronaSelect map.
Clouds look as expected in render background but shadows from clouds behave wrong.
It seems to me that CoronaSky in 0 slot of CoronaSelect map controls clouds amount in all other slots, or something like that.
Same problem happens in corona 9 and latest corona daily build, max 2023.
Simple max scene attached, try changing clouds amount in map0 while map3 is selected as active.
