UV stretching in mission editor

I have been doing some tests lately with the terrain editor. One thing I cant help but notice is that when I extrude the hight of a hill/hole the textures (from standing on a horizontal axis) apear quite streaked and end up looking.. somewhat artifacty. I am assuming that Torque only renders the terrain maps down from the vertical axis. I guess there is no simple solution to this, asside from re-coding major sections of the engine? OR is there a quick had for say, doing FACE mapping so the co-ordinates are not all restricted to the one axis?

It's late here so I hope I'm coming across ok.
