I previously had an issue where I had small seams, but I fixed them. I was super happy because in Tiled, everything looks perfect. However, in the Preview Map option in Tiled2Unity and also inside of Unity I see huge lines in between tiles. It almost looks like the tiles are inverted or something. Anyone know what is going on??
The drawing order seems wrong, the top tile should be painted first whereas now it is painted last.
I finally figured it out! I am not sure how to fix it if you are using regular Tiled2Unity. If you use SuperTiled2Unity, once you import your map into Unity, click on the prefab. Change Layer/Object Sorting to Overhead Static, press apply, and it should be fixed!
