• 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.

FSX Strange issue with landclass

I am doing a freeware thing which redesigns a coastal area. The area has very low ground profile (up to 5 meters) and it has some ports for ships as well. I am using SBuilderX x64 and both QMIDS have an enclosing Exclude Shorelines.

One of the issues is with the container port. I am not (so far) making a model for it and instead just created a polygon with class LC_Cement which covers the container area as well as the 4 docks where the large cargo ships dock. I set this poly to constant altitude 4 meters. But what I see when flying over it is that as it nears the coast where it should protrude into the 4 docks, I see the coastlines that define the docks BUT the cement surface seems to sink into the water so the container area shows with cement but somehow the 4 docks are showing water with a cement triangle sinking underneath.

Another problem is another coastal poly which is kind of round around the coast, inside I filled it with a Forest polygon. But when flying over it it appears as if you have taken an X-Acto knife to cut the circle almost in half, one part shows land and the other half is filled with water instead of showing all land.
 
If I understand your problem correctly it sounds like the default FS coastline is still present and affecting the new coastline you are trying to create. That has to be excluded with an Exclude All Water Polygons).
As I described in your other thread. The new coastline will have to be redrawn using holes set in a new hydro_polygon.

For your second problem, it sounds like the polygon you are trying to draw may be covering two QMID grids. Not sure about the reason for the behavior, but perhaps a photo of the vectors you created in your BGL viewed in TMFViewer might help.
