Blending Textures between Terrain Meshes

Background: I’m needing to break my terrain mesh into separate pieces in order to increase the relative quality per piece of terrain (break 1 x1024 grid into 4 x1024 grids as an example). The breaking part is easy, but blending the edges of these separate pieces is not (and is very time consuming to try and blend in blender or photoshop).

Question: I was wondering what the best method was to accomplish blending textures between the edges of separate terrain meshes.

I would try to use object coordinates to place a tiled texture. Use an empty for doing so. You can always bake the textures then, to further paint in an external program.

I’ll look into that.
