Unknown Terraforming flattening my airport

Hello,

after working on my ENOL Orland Scenery in Norway I suddenly found that the terrain height increased out of nowhere. And that a large area around my airport was being flattened.

So far I cannot find the cause of this issue. In the terrain debug mode I can see two rectangles but no package name or anything related to them. They flatten the terrain around the airport and disappear when I load the scenery in the scenery editor. When exporting it to my community folder and testing the scenery the terrain issues will appear again.

The yellow rectangles are what causes the terraforming. I have not placed these. This image was taken with only the the project opened in the Project Editor.

This screenshot was taken after opening the Scenery Editor and loading the scenery BGL.

So far I have tried:

  • Exclusion rectangle around the unknown rectangles.
  • Uninstalling and installing the two Nordics packages with the content manager.
  • Creating a new project and moving the old XML contents to it.
  • Turning off/on photogrammetry while editing and testing.

Other information:Airport flattening is turned off.

  • All terraforming polygons are inside the airport area.
  • There are no other sceneries loaded around Orland.
  • SDK version is 0.24.5.

Hello @PervonHarke

Are those terraformers visible through the Debug -> Terrain -> Debug Shapes DevMode debug?
If so, can you please check what’s displayed when checking the “Draw package name” option?

The text for the package named pervonharke-airport-enol-orland aligns with polygons and taxiways placed down by me. The “vertical” line in Image 2 and 3 that intersects all the manually placed polygons etc. is from the generated airport shape. The yellow unknown line lines up perfectly with it.

Hello @PervonHarke

These are the shapes on the generic airport:

Your first pictures mention the Scenery Editor is not open, but still we see some shapes from your package, so you have a Community version of your package mounted already.
The debug is unclear, but I think the shapes with fs-base-genericairports title you show are the orange and green one, not the yellow one.

Can you follow step 3 here and provide us with a version of your project please.
We need to investigate further.

Hello @FlyingRaccoon

Step 3 in the post you linked has been followed and a message has been sent.

Apologies for my unclear wording. When saying “taken without scenery editor loaded” I meant actually loading the scenery (file?) through the scenery editor window. When doing this the terraforming goes away. See images for before and after selecting the scenery in the scenery editor.

Before loading the scenery in the scenery editor.

After loading the scenery in the scenery editor.

Hello @PervonHarke

We have identified the problem, it comes from your terraforming polygon located here (GUID 359C73E8-06BE-4FB2-ABCB-EC942F7761D0):

It self intersects (8 shape), and is located right on the junction between two tiles.
The engine does not handle support this very well and generates the 2 big rectangles instead when building the package.

Just make sure it does not self intersect and it will solve the problem.
