Terraforming on 2020 project not working as expected on 2024

Version: * 1.0.72.0*

Frequency: Consistently

Severity: Blocker

Context: Loaded 2020 project into 2024, Rectangle with heightmap not working as expected, seems not to apply falloff correctly

Bug description: Falloff seems to be ignored on FS2024. Terraforming that worked on 2020 does not work on 2024. Polygons with terraforming and rectangles seem messed up

Repro steps:. Load Scenery into 2020 community, observe terraforming

yes, I have this a lot. Here is an extreme example.

@milosanxx What are the falloff values for this one? Could also be that your heightmap is based in older elevation data which may have changed in MSFS2024. But that of course only makes sense if your falloff values are rather short.

Between 100 - 500

New elevation data would affect but still a falloff of 100 did not generate such a sharp cliff on 2020.

I always found falloffs caused problems when doing this scenery, kept it to minimum. (1)? I even have long bush tracks with multiple rectangles joined together.

I cant recall and not helpful for a 2020 to 2024 folder throw in, but can these rectangles be moved up in altitude and still keep their form?

Heightmaps always have been a bit of a mystery. A falloff value that works somewhere doesn’t necessarily work somewhere else and vice versa. Let’s hope that things improved in the next build?

Terrain falloffs are still behaving very differently in 2024 compared to 2020 (1.0.77.0)
The falloffs are much less smooth.
