• 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.

I want to add a small lake

I'm still totally confused about terrain polys and ground polys, I just can't make them work. I want to add the circled lake using the terrain polygon tool, I added the polygon around it and chose Water with Perennial Lake, then added a vector around it and chose shoreline with Lake as a tag and nothing showed up after compiling. Removed the vector and the lake showed up but looks very fake, just terrible. Tried adding the lake with polygon with other options and nothing shows up. I'm totally confused on how to use this tool properly. Is there a good tutorial just on polygons and how to use them. Not just clicking on the polygon tool and drawing the polygon that is easy the hard part is creating what you want and see it in FSX.

If you did not compile the airport directly into an active scenery folder, did you copy ALL BGL files produced. The _CVX file contains the terrain polygons.
 
Yes, I've testing with several "Poly layers" now, a flatten poly, an Exclude General with "Airport Backgrounds" tag and then another with Landclass or Water. I'm getting some results but not exactly what I want.
 
I've had to create many lakes where they are "black, dry beds" instead. (Mostly Alaska Area). I first put in a flatten poly, making sure my start point is at the lowest level of the proposed lake. Then I create the polygon trying to follow the shoreline. When Completed, I do a Terraform and set the falloff to 1 meter. I wait a minute or so and t he polygon finally settles down and I have a flat polygon in the shape of a lake. I then remove the "starting point" that was at the lowest level. I now DUPLICATE that polygon and rename it to "terraform water". In this new polygon, I unchecked terraform and check WATER and add LAKE as the type. In a minute or so, the old black polygon magically becomes water. And I have a lake. I've done this about 50-60 times throughout the RTMM area. (for adding the USFS Cabins).

My question is what to use for the "type" of water. Often I use LAKE and it works, as above. But other times WATER works and LAKE does not. OCEAN often works, but sometimes gives a deep cut shoreline around the lake (50 meters deep!). I still haven't figured out except by trial and error, which "water type" to use. So in some "lakes" I have OCEAN as the type, others have "WATER" and/or "LAKE" ... I just go with what stays and works. This is using the new SDK (today's date is: 06.20.2023). Same questions for the water Exclude ... sometimes LAKE works, other times OCEAN and or WATER. I don't see any pattern. Supposedly with the new "terraformers" all this has been settled ... (but not for me!) :-)

You probably want to start a new thread. Make sure to use the available prefix options and choose “MSFS.” This will offer you the best exposure to experienced developers who do not check threads from 2019, before MSFS was published. This thread likely refers to FSX.
