Right two little problems im trying to get to the bottom of
The first is more important than the second.
In some parts of my scenery (created by me- ive replaced both the terrain mesh and the aerial photo textures), the river sticks out of the scenery (see pic)....why? What controls the height of a river? how can i fix this? Ive also noticed that the lake levels arent quite correct? (not as bad as in FS2004 but the terrain data i have is more trustworthy than whatever FSX is using...)

The other problem is in default data- flying over Aucklands motorways, occasionally cars will appear as if driving vertically.....is this a known problem?

Cheers
Tim
