Recently I've been experiencing these strange raised terrain with water bodies on top of them. This is happening around Seattle KSEA and Chicago KORD but probably in the whole US as well. But it was fine at frankfurt EDDF and Munich EDDM. Any suggestions???Is it a mesh problem? If so can i download some mesh files to fix them?Thanks guys~Eien

Looks like goofy mesh. Did you recently install some add-on mesh?Greg

I'm not entirely sure. But I have the same problem with the river running along the edge of Renton. Most of the lakes and large rivers in the Alaska region are doing the same thing. From what I can tell, this is the same problem as with the airports. The lakes, I'm assuming, are set to a specific elevation and flatten there. With new mesh, the elvations were lowered or raised and the lakes now appear risen or sunk. So if I am correct in my assumptions, the lakes would have to be altered themselves to go to the new elevation. The implications of this are troubling for large rivers like the Yukon in Alaska though, as it's made right now, it's a bunch of large narrow interconnected lakes with streams running between, causing a terraced look to it. This means that you could not make large wide rivers, since rivers are not level like lakes. But this is only from my observations in the Alaska and Washington areas, I have yet to see how the Missessipi was done. Although Lake Hood in Anchorage appears to be a hill of water and not flat at all with the higher resolution mesh, although I believe the Anchorage area is for the most part, a satellite photo.----------------------------------------------------------------John S.

>I'm not entirely sure. I take this to mean you probably have installed some kind of addon sceneryStart uninstalling whatever you have put in recently - one thing at a time- in reverse order- it almost certainly must be bad mesh (as suggested above).The mesh itself may be for areas hundreds or even thousands of miles away - the effects of faulty mesh can manifest themselves far away from the installed areaI've seen this before somewhere relating to the NW USA(possibly on Avsim Forums- try a search on "Bad Mesh" etc)Dave

John (Sentirus) is correct. This topic has appeared before with the same problem concerning airports; as he also mentioned. It's something to do with the fact that FS9 cannot model surfaces like runways on a slope, and so any airport that is on sloping ground will find itself appearing as though on some kind of a 'shelf' of falsely raised ground. The same also applies to lakes; as the ground around them slopes, the lake appears in a raised, almost 'bath-tub' like area of ground. I'm not sure if it would be possible, or practicle, for the mesh designer to sink the lake lower into the surface of the terrain and then more gently slope and smooth the ground around the lake. Given the number of lakes and rivers, if it were possible, it would take one heck of a long time to do!!This odd 'feature' is unfortunately global, and not just confined to the USA: a great many European airports have a great 50foot high ridge of cliff falling away from the head of runways, and man-made looking bath-tub lakes sticking up out of the ground!It is present in the default FS terrain, but exascerbated by the use of more detailed add-on terrain.

DOes this mean we have to stick with it???no solutions???even installing a new mesh instead of the default?ThanksEien

If I'm not mistaken, setting the TERRAIN_MAX_VERTEX_LEVEL=20 in the fs9.cfg file to 20 or 19 instead of 21 can help alleviate the problem some, but of course this lowers the mesh resolution a bit too - personally, I can live with less mesh res easier than the raised lakes and airports which look totally goofy...

Just for comparison - this is the same location using Raimondo Taburets mesh for the area.Davehttp://forums.avsim.net/user_files/92259.jpg
