Adjusting the static lighting scale isn’t probably the best solution though as will increase light build times the more your scene grows and is not only for the single objects but all objects.
The main things to check are that you’ve built your lightmaps with the hard edges snapping the grid for your target lightmap resolution (covered in the post above) and why is important.
Adjusting the world settings you can help reduce by adjusting the Indirect lighting smoothness to .6 and the Indirect lighting quality to 2. I would start adjusting these settings before ever touching the lighting scale option. Usually these settings will help as a starting point.
Feel free to ask any questions as they come along.
Thanks for reply.
I tried lighting smoothness to .6 and the Indirect lighting quality to 2 and even 4 but didnt work.
One thing I am sure that it is not about lightmap padding.
It is about indirect lighting. If I set indirect intensity 0.0 on Post-Processing volume, it totally fully disappears.
Once more, the reason of problem is within indirect lighting.
I dont even remember I saw artifact on previous versions. It could be after 4.4 or 4.5.
It is not our mistake or something. It is clearly a problem within engine.

I have similar problems.
In the post above you wrote that the grid should be 1/128 but on answerhub you wrote that it should be 1 / (128 - 2) for 128 resolution. Which one is correct?
Which padding should I use between UV shells? And how much padding between UV and the border?
In most cases I would say 1/128 is perfectly fine, but there may be cases where you would want to use the 1/128-2. I’ve just not run into an instance where I cared enough to set my grid to that.
The test cases where people mostly point out the differences are with a single color base for you a wall where they can see the seams. If you set the Indirect lighting quality and smoothness in the world settings should reduce it to the point when you have a legitimate diffuse on your mesh with normals and other details you shouldn’t see seams. Again, is most cases and tweaking will be required.
