If you take a closer look, I am changing one thing at a time. My point with the first two pictures is that RGB doesnt change (80 - 64 is no change), while I "jack up brightness" like you told me which doesn't bring me the darker result I want. This is why I tried both 20 and 200 brightness.
What happens here is not just my
shadows being too bright, it's the whole room being overlit.
Now that we're onto something here, I will edit this post with some results about shade brightness so we can better understand this, unless someone knows it beforehand.
Brightness 200 130 130 50
Shade 64 0 0 10
