I have made a wall tile and floor tile in Blender and successfully imported these objects into Godot. I have also added these objects to a meshlib and can place the tiles into a new scene. So far, so good. Now for my problem. The floor tiles snap together properly and the wall tiles snap together properly. I am having trouble snapping the wall tiles to the floor tile. See the attached image. How can I get the wall tiles to line up on the edge of the floor tiles? Thank you in advance.
