Sorry to bring this old post up, but I need help on the same topic...
Suppose you have more than 2 types of tile and they are all next to each other for example:
green = grass
yellow = sand
red = rock
How would you decide which tiles should blend and which verts should have what alpha and which textures need to be used for blending?
I know that one work around I can use is to have a base tile type (eg grass) and then keep all other tile types at least 1 tile apart (with grass in between) but it would be cool if there was a way to universally blend any combination...
