• 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.

MSFS20 Cleaning Up Large Areas of Overdense Vegetation

Hi everyone,

There is an issue with the automatic vegetation near my home airport and I am wanting to clean it up. I think the problem stems from the fact that the color of the satellite imagery abruptly changes, and the sim is adding way more autogen trees than it should. You can see in the attached screenshot that everything on the left looks correct, while there are far too many trees on the right.

I'm not terribly familiar with the MSFS SDK yet, and most of the tutorials I'm coming across only deal with manually editing things like airports and landmarks. I was hoping someone could point me in the right direction or provide an example of how I might go about editing the vegetation over a large area like this.

It will be quite simple to do, once vegetation customizations are again enabled in polygons. The latest update broke them and they are promised to be repaired by end of May, I think is the next update.
 
I just checked and I seem to be able to draw a polygon in the scenery editor, check the 'vegetation' box in the property window and play with the 'vegetation scale' and 'vegetation density factor'. Is this what you're referring to?

The problem is that changing the sliders seems to make the vegetation density completely uniform throughout the polygon. Is there some way to tell the sim to place vegetation according to the satellite imagery (like its doing in the left half of the screenshot I posted), but to be much more judicious about it?
 
I can't offer the same degree of certainty that the jagged edge reflects an abrupt change in color of underlying satellite imagery. Satellite imagery transitions on a line, or at a corner of several tiles, but the jagged edge is unfamiliar to me. Also, I am not aware that vegetation, beyond the ubiquitous grass, responds to color changes. When you create a satellite photo derived ground polygon, all vegetation is excluded, except for grass.

If it is possible for vegetation to automatically generate where the ground is dark, or green, or bushy, there is no setting to adjust that.
 
So I did a little digging on the MSFS forums and I found a solution. Posting this here for anyone who comes across this issue in the future. The sharp boundary in the screenshot I posted is actually due to the terrain type transitioning to 'default' past the edge of the city (which also happens to coincide with a change in the color balance of the satellite imagery). Outside of cities, MSFS has a number of biomes defined, which can include different vegetation types. This is all contained within the \OneStore\fs-base\vegetation\10-asobo_biomes.xml file. There is a 'spawn ratio' parameter for each vegetation type, which controls how densely the plants in that biome populate the terrain.

Tree density

NB: I’ve posted this in another topic a few days ago: Tree density is preset in files (most likely). For example: \OneStore\fs-base\vegetation\10-asobo_biomes.xml <BiomeRule name="Cactus" speciesInstancesPerHectar="200" artificialSurfacesScaleFactor="0.6"> <SpeciesList> <Species...

Within each biome entry, there are a list of EcoRegions, each of which corresponds to some geographic location in the world. The EcoRegion I was looking at appears to have been placed under the incorrect biome by Asobo. Moving it to the correct spot in the xml file produces a much more reasonable foliage density around the city (and makes that jagged edge in the scenery much less prominent).

In any case, thank you for the help!
 
Asobo messed up the EcoRegions data (their source was OK, but someone altered it). Lots of vegetation is wrongly assigned and many biomes are just wrong. I made a world-wide set of polys and biomes to replace the default. I don't know if this is helpful for you, but here's a link: rhumbaflappy-vegetation

Polygons and biomes can be adjusted for smaller areas as well.
