Weird Lighting After Building Ligthing
Before I built lighting, it was quite good with temporary ligthing on the viewport. However, after I've built lighting, every road pieces on the spline meshes started to show different brightness. I tried building on preview, medium and high but result is same. I tried replacing my materials with the ones that are in starter content, but result is still same. How can I fix this?

It looks like a light map issue. I would check to make sure the light maps are of at least 32 pixels. Also make sure that they have a decent light map UV layout (ie no overlapping UV's and all in the 0 to 1 space) and usually not in the same channel set up to use your textures.
If you are sure you have a good layout and the resolution is of adequate size, another thing you want to make sure of is that the asset is using the right UV channel that you want it to use for the light map and not your 0 channel.
The documentation has a good [article on the best practices for building light map uv's here:
If you need more specifics on how to do any of these checks let me know.
