Texture Blending in a Terrain
I am currently trying to make a tile based engine, each type of tile having it's own texture, I wondered how it is possible, when two different type of tiles meet, to make a progressive blend in between the two, using some sort of interpolation.
I have already played(without much success) with the ARB extention, I managed to mix 2 textures. But it's not really what I seek.

Thanks for your time.
