I tried to add the road tile with markings on top to the generichouse, but I found a bug related to the texture atlas. If there are more different tiles on the map, the tile atlas texture will be bigger for that chunk and it is more noticable that a margin is cut off the tile. In chunk.gd the create_atlas function does not have a margin for tiles, but prepare_mesh_data does use a margin for the tiles. It's only 0.01 but it becomes noticable when more different tiles are added and the atlas is bigger.
