Is the method arras describes here the only way to blend more than two textures without using custom shaders?

While we're on the subject, I'm not entirely sure blending multiple textures is the best solution to my problem. I'm working with a subdivided icosahedron mesh representing a planet. Each vertex has a terrain type associated with it, which will sometimes change, but not often. I was originally thinking about creating a layered material containing all the terrain textures and using the same tile for every triangle. But now I think it might be faster/simpler to texture the whole planet with one large texture, and re-generate it whenever a tile changes. But I'd need a separate graphics library for that, wouldn't I?
