I guess you're talking about the slope pattern, not slope maps for
normal pertubation.
The slope pattern is not a true 3D pattern - it is only defined on the
surface of an object (after all it needs a normal vector); so it doesn't
make sense to move it around separately from the object. Instead, the
slope pattern always "sticks" to the object it is applied to, as far as
translations go. (Note however that the slope pattern's "up" vector
stays fixed all the while.)
The same goes for the aoi pattern, by the way.
