Hey, I’m experiencing a problem with the map once I get it imported to Unity. Lines seem to appear on the map only in Unity. They weren’t present in the Map Preview. I tried searching for a solution, however most of the problems seem to be with grid lines. These are how the lines that appear on my end look.
Those are seams. Do you have anti-aliasing enabled? There should be a warning about that in the Console window in Unity when you export.
