I am designing a rectangular tilemap where the tiles are 64x64px, but the top 16px are meant to be stacked over the tile above, so that shapes such as tall grass and sand dunes rise above the tile. Thus, each tile must be placed only 48px below its neighboring tile, while being 64px in height. Can Unity accommodate such stacked tiles?
This image shows how, in each tile, the grass rises above the 48px-high blue line:

EDIT: another example: in the image in this link, the mountain tile images on the bottom-left go above the bounds of their tiles. This is what I’m aiming for and I would like to know if Unity accommodates that.
