Runway goes under the ground

[tulma]

Hi everybody

I've a problem, appeared with Prepar3D V5 on only one of my aiports : As shown below, the end of the runway, on one side, goes under the ground.



I had to modify a little the geographic coordinates, because the stock ones are not correct. To do that, I used ADE 1.79, the last version, and I created a background poly set as "flatten" and another background poly "Exclude Specific Airport Backgrounds Flatten MaskClassMap Autogen" to remove the stock data.
It's not the first time I do that, but usually, there is no problem.


Somebody has an idea to solve this problem ?
Thank you for your help

[tulma]

Up,
does anyone have this kind of problem ?

You yourself have changed the airport, so only you have this particular problem...
You better ask the ADE forum.
As for the broken airport by default, just report it here with a screenshot and ICAO.

[tulma]

Thank you Niksan

It's already done on the ADE forum. But no solution was found.
In fact, it's very rare.
I sometimes modify a bit the coordinates sometimes so that they correspond exactly to reality, but it's the only one of my airports with this problem.

On the screenshot, we can clearly see that my surfaces correspond exactly to the satellite image.
The airport is LFMV
Coordinates :
43.907306
4.901822
Must I create a specific topic ?

I think the best topic for this would be:
viewtopic.php?f=6312&t=137107&p=215320#p215320
I already mentioned your problem there.

This one is more of a custom airport question. Variations on imagery from headings and other distortions are common and you have to adjust for those in add-ons. Is there a custom mesh or model involved here?

[tulma]

Hi

Thank you for your answers.

Max, I don't undestand. I made this airport like the others. I modeled the surfaces, buildings ... And placed them using a background picture from satellite/aerial views (Google, IGN ... ) .

I also create a flatten background to be sure it's perfectly flat and elimate possible faults ...normally this should fix the problem. It's the case usually but not this time.

I specify that the problem does't exist on prepar3D V4. It appeared with Prepar3d V5.


I can't change the coordinates of background image of course (they are correct).

Trying to found a solution, I changed the coordinates of my airport to stock coordinates and the problem seem to disappear. Of course, in this case, the airport is offset from the reality (50 to 60m).

Maybe a problem with the bakground stock airport in P3D V5 ?


Niksan I saw, Thank you

[tulma]

Oh, I forgot your question :
No I've no mesh here.

And I think it's due to Prepar3dV5 since I've no problem with the same scenery in FSX, P3D V3 and V4

Hi!
By the way, is this a free scenary? You can share it? And I'll see ...

[tulma]

Hello

Sorry for this late answer.

I send you a PM :)

[niksan29]

I send you a PM :)

hi!
received by me, but because you didn’t give scenary to me completely, it looks completely different for me than for myself I cannot reproduce the problem...

Also, it’s not entirely clear to me what difference in coordinates you are talking about:

because the stock ones are not correct.

As we see in the screenshots above, your texture is almost perfectly in the default runway coordinates?

Nevertheless, there is a small problem with the stock scenary, I think it needs to be cropped a little and correct the runway end:

This one is more of a custom airport question.

Max, can you fix it?

[Max Perry]

I can remove the unnecessarily long and weird shaped airport background. It may be based on some actual data, i'll go look. I'm still not sure what the other issue is though.

[tulma]

Sorry.
I send you a new file :)


Max, you can see the problem on the first picture sent by niksan, at the bottom of the picture.
My runway texture goes under the ground before the end.
it should go almost to the end of the default black texture

[Max Perry]

Have you changed the airport elevation at all? You might need to extend the default runway to match your custom one better, in his screenshot they look off.

[tulma]

Hi Max
No, I did not changed the elevation, the default one is ok. I only changed the coordinates
