When Microsoft defines a river course through a city with complex terrain, it often gets it wrong and as a result, one can sometimes see an ugly gash cutting through the wrong part of a custom photoreal image. I will fix this with many, many hours of tedious work using Ground2k (a marvelous tool). However, since I have FSGenesis custom terrain, I thought I could run this mesh at a higher priority,(1) than my photoreal scenery, (2) and the custom mesh would effectively override the lower priority default river course errors in the FS9 terrain. It doesn

HI John,Because terrain doesn't use the same priority rules that other types of scenery do, and because the rivers are constructed using a different schema, independent of the terrain, having their own hard-coded elevation (flattening) data.-------Justinhttp://www.fsgenesis.netHigh Quality Scenery for FS200x
