Graphical error in Unity

[SSG]

Hi, I’m having an issue with my Tiled maps in Unity.
After I export my maps to Unity, I get some weird graphical artifacts.

As you can see in the in the images I included, in 3D mode, there are these 1px lines around each and every tile. These lines are only visible in Unity and not in Tiled.

Does anyone know what the cause of this might be and how it can be fixed?
Thanks!

It’s probably the common Tile Bleeding, you can find a lot of topics on it, for example here: Texture Bleeding and Partial grid lines a tilemap

And a solution would be:

To avoid it, either put a thin border (usually 1 pixel is enough) around your tiles that matches the color of the tile edge. This means you need to space out your tiles to allow for 2 pixels of space in between. Or you need to make sure to render the map at 100% scale and at whole pixel positions. Alternatively, sometimes it may suffice to disable texture filtering (setting it to nearest-neighbor instead).

Putting a 1px border around my tiles fixed the problem!
Thank you for your help!
