What I mean is that from a "top down" view you need to increase the resolution of textures on the slopes so that when you look at the slope from a perpendicular angle you still get the same resolution as on flat ground. Example : If a flat piece of ground has a texture resolution of 1m/pixel then a slope of 45 degrees should also have a texture resolution of 1m/pixel if you look at it from a perpendicular perspective. A 45 degree slope viewed from the *top* should have a texture resolution of 0.707 m/pixel. So from a "top down" view the texture resolution will be higher. This will "unstretch" those slope textures.
