I am aware that some level of overlapping is present in the screenshot however I can’t close off the hole in the middle.
The situation is caused by triangular tiles not having the same length as square tiles.
When I say “length” I don’t mean the length of one side of the triangle, but the height itself (in geometry terms).
I’m not sure if making the triangles the same height as the squares will fix this thing. Perhaps adding right-angle triangles might solve this.
In that case I am fine with overlapping tiles as long as they are considered “connected” and not a non-collision piece.
FYI - I can still fall through that hole.
