• 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.

Problem creating airport on rough land

Hi all,

I’m trying to create an airport over an island where there is a small lake. The airport area covers both the original ground and the lake I’ve used a polygon to falten (terraform) the area and exclude vegetation and water, and built the airport over such polygon (runway, taxiways and aprons).

Everything looks fine visually, however when taxiing or taking-off from the runway you can feel a lot of bump and resistance on the wheels, like if pavement was not recognized and you were running over the ground... also, on the G1000 GPS you can still see the (excluded) water just below the runway (you cannot see it visually).

I’ve played around with the priority settings for the polygon and aprons, and also checking/unchecking the “merge with ground” option but nothing works...

Any hints or ideas on how to solve this??

Many thanks!!
 
Have you tried putting the runway inside its own rectangle? I've found polygons don't do a flawless job of flattening.

Do you mean placing an exclusion rectangle right below the runway? I tried adding a big exclusion rectangle over the lake (which would affect part of the runway and part of the taxiways), but nothing... for some reason the game still “thinks” there is “ground” were should be concrete... the water is still visible in the G1000, but I can cross through it with a Cessna so I guessit recognized as ground instead of water (otherwise the plane would crash while crossing water)

Not sure if I’m doing some ring wrong or is it a limitation of the actual SDK...
 
I had a runway with a similar problem. I created a rectangle, not an exclusion one, and placed the runway inside it and hit terraform which overrode any lumps. That cured the lumpiness but I did have to fiddle around with the aprons and taxiways outside the rectangle to get them to feed onto it without huge ridges where they meet. You have to play with the rectangle's falloff distances quite a bit.
 
I’m afraid it didn’t work either... it seems a problem of “type” of ground recognition rather than flatness... maybe something related to the collision with polygons?

Is the runway asphalt or gravel? Gravel does that. If you post your ade file I could look.
 
I'm really sorry I forgot to check the forum until now, I will look unless you have sorted it?
 
Finally found the issue (I put it here so it helps other people making the same mistake):

The polygon “below” the airport (the one that flattens the surface, removes vegetation, buildings and/or water) had its “Surface” parameter set to a “grass” material. I mistakenly thought that placing taxiways, runways and aprons over it (with a higher priority setting) would override the polygon surface material but it seems not to do so.

Changing the polygon surface to “concrete” solved the issue for the whole airport.

Mu guess after this is that materials of taxiways, Runways and aprons are just textures for visual references, what defines the type of ground you are over is the Polygon Surface parameter.

hope this helps to anybody else and thanks for the replies!
 
Got this problem at the moment. Not a single thing is working for this one place. No idea why.

Polygons, including the above tip, rectangles, runway profiles, new runways. Nothing stops the runway from being a lumpen mess. Next up is starting all over again but I pretty much have with the existing project.

Very strange.
 
Now got this with ANOTHER location.

It is perfectly smooth until you add the runway. For some reason the runway is turning the land into a rippling mess. Before that it is absolutely flat as a pancake. Is there an obvious setting I'm missing here?

With no terraforming at all the land is flat enough. As soon as the runway is applied it's wavy. Deleting the runway snaps it straight back.

Adding a polygon and terraforming halves the ripples but no more.

Photo 1 is the runway dropped on to the polygon with nothing done to it.

Photo 2 is after deleting the runway.

The thing that both of these problematic areas share is that they're in the Arctic where the quality of terrain is awful so perhaps there's a different sort of mesh or something, but everything other than a runway flattens perfectly.

On checking Asobo's own airports in this area all of their runways do the same thing. Must be an innate issue of some sort.

I think I've discovered what's wrong with my current area at least. It's completely plastered in these raised squares which must be under the runway. These don't show up in developer mode but just have in the latest build. Has anyone come across these before and is there any way of dealing with it?

It looks like it only happens on areas where you've applied something. The untouched terrain doesn't appear to have it.

If I raise the polygon then they're inverted so there's some sort of innate fixed height maybe.

A tech alpha insider pointed me the right way. I would never have figured this one out.

A runway has an intrinsic terraforming value of 10. If it's giving you trouble of this type then your polygon or rectangle around it needs the priority increased to 11 or above. That tames it.

Damn so you´re telling me there is a way to disable the runway terraforming? My workaround was to put the runway into a terraforming rectangle and give both the runway and the rectangle the same terraforming profile. Then all bumps would pretty much be erradicated and I´d also have the desired runway profile. But it´s cumbersome and often needs some fine adjustments.
 
It instantly cleared up all the problems I had with multiple runways, so I guess so.

Not one single thing worked until someone told me that.

I haven't tried it to bend to any desired terraforming other than flattening but I presume it applies too.
