Can't remove trees around POIs in World Update 18... why?

Dear all
I’m trying to remove some wrong placed trees on mountains around some of the new World Update 18 PIOs.
For example these trees here (red circle) at Mount Pilatus near Lucerne/Switzerland.

I just drew some usual simple polygon, set the vegetation slider to 0… but these trees just wont disapear.
It’s like they are backed into the scenery now cause of the nearby PIO…
The PIO could be removed with an exclusion rectangle… but that’s not what I want of course.
I just want to remove these normal MSFS trees in the red circle area because they don’t exist in real life.
But unlike other trees in other areas, these just won’t disapear :confused:
Any ideas? Coordinates: 46.978574, 8.250422
The same issue also exists around some other of the new PIOs…
Thanks a lot, Oliver

Most likely those trees were manually added with a polygon
So to remove them you need to add an ExclusionRectangle
And in its properties select excludepolygons

Thank you very much Federico
I tried this… but it does not work :confused:


The tries don’t disapear… not with excludeall, not with excludepolygon :confused:

I even created a gigatinc exclusion rectangle that was as large as the whole mountain… but these trees just stay there :pensive:

Are they photogrammetry trees? Have you tried suppressing photogrammetry?

Ah no no, it’s not photogrammertry/TIN, it’s normal MSFS trees/vegetation.
That’s what makes it so strange that it can’t be removed.
It’s like it’s backed/hardcoded into the sim :weary:

Just checking – did you build the scenery and reload the sim? Some aspects of exclusion rectangles require this.

Coordinates?

I did. No difference.

46.978574, 8.250422
Would be great if you could try it :slight_smile:

I’m unable to check the WU at the moment, but seems a duplicate of this

It was solved using a polygon with override biomes
(Actually the ExclusionRectangles should have worked too)

Also you might want to try to place the compiled package in community

I have a vanilla MSFS. Nothing in the Community folder. No paid marketplace addons. I do not have those trees. You must have a 3rd party addon making those trees. Mamu’s suggestion is a good solution. If the compiled package in your Community does not use the exclusions, then you may have a naming convention problem with your package, forcing it to load before the 3rd party addon. Your package needs to load last.

Well, that’s a little bit pointless. Of course you need to install the World Updates as well. Both World Updates that are covering Switzerland.
So World Update 6 and 18.

If you install thouse and check again, the trees will probably be there.
And the point is not that they are there… they point is that they can’t be removed

My install has all updates and contains no 3rd party addons. That is what 90% of developers need for development. And the point is you may have an addon causing those trees to appear.

No one here can help you as we do not have those addons. Once you find the addon package causing the problem, examine it’s name, and see if your package name is alpha-numerically later than that addon name. If not, then rename your package starting with ‘z’, and see if the problem gets resolved. That is naming convention.

I appreciate your help… but I think you are missing the point.
It’s not caused by an addon.
Just install World Update 6 and 18 and you will see.
This issue is new and seems to be caused by the PIO of World Update 18.

You don’t have this installed… as I can see in your screenshot because the PIO is not there.

So therefore you don’t see the problem.
But I don’t think just not using World Update 18 is a solution ^^

I just checked my sim. You are 100% correct. I had not installed the World Update XVIII. I tried a variety of solutions, and there is none, excepting uninstalling the world update. You can change the biome with a polygon, but that is of little value for you. This is definitely a bug in the world update.

The trees can be removed by a combination of an exclusion rectangle set to excludePolygon, and a new polygon set as Vegetation with scale and density set to 0.00

Hmm ok I see.
I managed it to work, also for example at the Brienzer Rothorn POI.
The problem with this method is however that the “excludePolygon” exclusion rectangle also breaks the POIs… at least in the Brienzer Rothorn case.
Because the POI has some terrain modelling going on and by excluding polygons, those get broken and then the POI won’t work properly anymore (the terrain stars to overlap the POI for example)
So… Not really a suitable method when they fiddled with terrain modelling polygons in a POI. It all falls appart with this method.
Maybe in the Pilatus area it works “by accident”… but in other areas… no :confused:
