This is the sand to grass tileset but with the grass removed(transparency), as you can see the grass shapes. So this tileset you're using is not meant to be used for this, there are other tilesets with transparency that transition to dirt, sand... In this last update I added neutral grass to transparency tileset so you can use it to make transitions to any dirt or sand. Did you see it there? If you are tying to find tileset that transition from sand to any tile then you can't because there isn't XD. The sand in this asset was meant to be used beneath the grass and not go further from the beach(possibly meeting dirt or any other terrain variation). However, I can add this tileset in the next update.
