   calculating a tile's texture
  hello, i have a tile-based terrain where each tile has a list of several terrain layers. like water, sand, grass, forest.now each tile has either one or two of those layers. what i want to find out now is, which texture to use for the tile. textures are either full with the texture of a layer or make a 90° curve with one layer on top and another one below.if it is one, then the solution to find the correct texture is trivial.but if it is two, how can i find out which texture to use? i need to get information. i guess it is some algorithm that takes neighbouring tiles into account.thanks.
