I am making a 3D game on Unity. Currently I work on main menu. The problem is when I use 16:9 aspect ratio I get this result:

The background is not scaled.

However when I use Free aspect ratio, I get this: Here is background object properties and sprite properties:

I have no clue what is the problem here and how to solve it. I hope to find some help here. Thanks in advance.

You should extract one tile of the background sprite like this:

Then it should be tiled correctly. The key is to extract the smallest repeatable element.

Also, you don't have to worry about the Free Aspect. Just make sure it looks fine on the real screen resolutions.
