World partition and 1:1 mapped textures on landscape


Trying to map orthographical satellite images onto a large tiled landscape in world partition. but since world partition divides the landscape up in uneven chunks where the landscape proxies are not in line with the world partition grid, nor the height data (my xX_yX.r16 files), i am having trouble matching the heightmaps of the tiled landscape with the satellite images.

Any tips would be helpful.

I have 6x10 tiles worth of heightmap (and textures), but i am getting 29x44 landscape proxies.
