Water polygon affects the terrain in FSX

[kmarek98]

Hello everyone,

I'm trying to do a landclass scenery for Romania using OSM data. Everything works fine, the forest, residential polygons and roads follow the form of the terrain but the water polygon dosn't do that. It makes big holes in the ground and puts the water on the bottom.

How can I fix that?

Hello:

CVX vector water polygons are flattens textured with a water class "color"; these require an assigned elevation for all vertex points ...which is set in the SBuilderX properties for the object as a "constant altitude" value.

See:

SBuilderX Menu > Help > Contents > Making Scenery with SBuilderX > Make Polygons > Polygons >Textured Polygons

Hi,

I've already found the solution. You just need to go to your FSX folder, find the terrain.cfg file, then open it in notepad and change flatten method to none, then overwrite the file. After that you can compile the shapefiles again to BGL. That's what I did and it worked for me perfectly.

Hello:

Thank you for taking the time to post your work-around.

However, I recommend NOT doing that, as it will change the attributes of all default and 3rd party custom add-on CVX vector objects in the FSX world which use that same GUID, and may result in many terrain scenery anomalies.

This may prove to be a problem even if you do not release your scenery to anyone outside your own computer.




If you wish to use "terrain-mesh-clinging" water polygons to make custom scenery, you can use:

* "Legacy_LWM_Water_Flatten"

...and/or:

* "Legacy_LWM_Water_NoFlatten"

...as another type of FSX-compatible CVX vector polygon objects from the land class pick-list in SBuilderX; these are enabled by installation of the "Modified Terrain.Cfg" at the time that SBuilderX is installed.

NOTE: These 'emulate' the way that legacy FS8 / FS9-type LWM vector objects function in FS at run time.

FYI: If you already have SBuilderX installed now, but did not allow installation of "Modified Terrain.Cfg" you can:

* use it as is, if you do not plan to utilize some of the enhanced and legacy-compatible scenery creation features

...or

* you can manually install the "Modified Terrain.Cfg" available via links in this thread:

CAVEAT: Terrain.Cfg should ONLY be manually edited by advanced users who know what they are doing, and who check their work at least 3 times after doing so !

It is best to not modify default or 3rd party add-on entries within the Terrain.Cfg file.

Only after considerable study should one add custom entries within the Terrain.Cfg file.

Please note that any modification of the default Terrain.Cfg file that is utilized in making custom scenery will require that any end-user of that scenery must also have the same custom entries within their own Terrain.Cfg file; otherwise custom scenery based on a modified Terrain.Cfg may not display properly ...or at all.
