As of UE4.21 the intensities to be set on light components such as a directional light (which I use as sun to light my scene) are explicitly phyiscs based. So I thought, looking up lux intensities for my sunlight, setting the intensity to 1,000 - 2,000 lux, corresponding to “Typical overcast day, midday” according to Wikipedia, would give me a decent sunlight for my scene. But rather everything is ridiculously overexposed to a point where auto exposure and explicit exposure setting in a post process volume wont help.
Obviously I am missing a point here, but after hours of seraching the internet I find myself unable to get any information on how to setup dynamic(I only use dynamic lighting in my scene) physics based lighting properly.
Appreciating all help!
