Add the option to use different HDRI images for background and skylight.
hey, I was thinking same, its really hard to add specially night scenes starry night or moons, it react as sun for moon, there could be option for moons and star as well,
also when you use HDRI it became too blurry, this is something that really need updates
Yeah. Also some clients want soft ambient overcast skylight while still having clear blue sky.
