I'm trying to make a TD 2D TopDown view. Actually the map is just a horizontaly line of title.
I use some asset from kenney.nl.
If i use the Navigation tab from TileSet menu like that :

BUT if a make this:

I don't get it, if i turn on the Visible Navigation in Debug it seems ok. (The navigation debug color change).

Thank you for your time.
Tell me if you don't understand me.
