Hi Paul, to my way of thinking the resolution is not important. Pythagarus
is more important, the distance as seen in a birds-eye view as seen by FGSD
is not the distance of the terrain. Hence if you cut a material to a
birds-eye distance of say 10 what ever units it will be stretched to say
14.14 units when the slope is 45 degrees. The greater the slope the larger
the slope distortion, in the nth degree a vertical slope will have zero
length stretched to infinite length.

When TerrorGear does the UV mapping calculations on the terrain polys it
should take the terrain slope into account.
Flat ground = standard resolution
More slope = higher resolution
