Player can't move to different tile in isometric tilemap.
I'm making an isometric tilemap using this tutorial: https://youtube.com/watch?v=OYn49ghh9k0&t=24s
This problem is mentioned in the tutorial however the solution isn't working for me. It uses Navigation2D and a navigation polygon on the tile. My polygon is perfectly 64x32, the dimensions of my tile, however the player can't move to a different tile. When I zoom in I can see that there is a 1-pixel gap between the polygons on all sides. I tried increasing the polygon by one pixel on all sides which creates some overlap, however that doesn't work either. The player still can't move to a different tile but can move within his own tile. Please help.
