How to get good quality shadows from static sky light?
I'm having issue with illuminating my scene with sky light.
On a screenshot below, light is baked with static skylight and stationary directional light. Directional light gives nice baked shadows, including shadows from light bounces. However, as you can see, there is also a lot of "noise" around it - it's what I get from baking skylight.
I want to achieve a smooth "glow" effect around the place where directional light hits the room. But no matter what settings to I use for lightmass, my skylight shadows are dreadful!
Is there a trick for illuminating scenes with skylight correctly?

I figured out what was causing the issue.
I turned sun brightness on sky sphere from 50 to 300, because I wanted to get the smooth glow of the sun disk, instead of it being just a white circle in the sky.
And because of that, skylight went crazy, and made that terrible shadow noise everywhere.
I thought sun brightness on sky sphere was purely cosmetic. But I misunderstood how skylight component works.
After I set sun brightness back to 50, my scene is lit correctly. However, now I can't make the sun to be "glowing". If I crank up bloom in post process, it messes up reflections so badly that they become blinding, filling the entire screen with white. And I can't increase sun brightness on sky shpere either, as it turns out.

I would raise the lightmap resolution of the bed. Turn off compression on your lightmaps... ...and would raise indirect lighting quality to 4-10! Are you using a HDRI cubemap? Do you have portal(s) in your opening(s)? ...lightmass importance volume?
