• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

FSXA SBUILDERX Flatten problem

Evening to everyone.

I'm creating some 3D objects to my project and I have little problem. After placing II world war monument onto the hill according the photo real ground it needed to flatten the hill little bit. So I created polygon in SBUILDERX around it and gave it specific altitude. The size of the polygon is something about 80 meters by 30 meters in size. I tried to make it with four vertexes only but it created to wide flatten on the hill. Then I created more defined shape of the surroundings but with same conclusion.

At first I tried simple AB flatten type of polygon and then Legacy LWM Land Flatten but with no avail.

You can see on the pictures how large the area is red circle and how big actually the monument is (blue).

Any help would be appreciated.

Thanks

If I understand your problem, it is how the flatten polygon transitions to the underlying mesh. I think it is mainly a function of the mesh resolution slider. You can try looking at different resolution settings. You might be able to get around some of the problem by creating some surrounding sloped flattens but that is a guess.

I was expecting that when I use flatten polygon of exact shape of the 3d object placing on photo real texture I will repair slope of the hill so the monument will not be placed one side in the air and another side into the hill. Instead of just changing shape of the hill just around the monument only it created flat area larger than defined by polygon as you can see on pictures.

Just added picture showing situation before flatten correction.

Any thoughts?

Hi Joe:

Legacy LWM flattens display in both FS2004 (aka FS9) and FSX, but size and shape of aliased edges vary in precision according to what terrain mesh resolution (and complexity) you have FS9 (or FSX) set for; borders of such flattens fall back to the nearest LOD quad QMID quad vertices.

The maximum terrain complexity that FS9 is enabled to display is additionally determined based on Terrain Max Vertex Level (TMVL) in FS9.Cfg; as this is not controlled by any sliders in the FS2004 GUI, it must be set manually (FSX controls this parameter with the FSX GUI terrain mesh complexity slider IIUC).


You will likely get more precise results using a FSX SDK compliant CVX vector type flatten made with SHP2VEC; perhaps even a "sloped flatten" (not to be confused with an FS8 or FS9 "LWM3 flatten") might better suit your described scenario.


There is some information regarding sloped flattens in this thread:

Hope this helps ! :)
