I have this problem too. I am using a translucent material because I wanted the dirt on my bottles to have different opacity values, but my sky light makes the dirt lit like if the walls weren’t even there. If I toggle my skylight off, my bottle reacts as they should, but I really wanted a skylight in my scene. I’ve tried all of the solutions above and a couple more on my end but didn’t find anything to make it better. If I really have to, I will place some lights to fake a skylight, but I don’t know if it will turn out as good…
Here’s three screenshots (one with and one without skylight, and another one with a rect light) :
