• 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.

FSX Runway vanishes at night...strange!

Hi all,
Finally got round to joining this community after being a long time lurker.
I've got an odd one here.
I've used ADE for a few years now and usually get on just fine with it and the learning curve has enabled me to improve my designs over time. A fantastic piece of software all round.

I've been working on a new airport at Greenham-Common (EGVI), U.K. using Brian Clarke and Daryl Paynes' FS2004 scenery converted over to FSX. All the Library Objects, etc have been brought over to FSX and I've created the Airport Background. After a bit of pushing and pulling the airfield around a bit (I have a Pro Key) we got the altitude and flattens spot on. The aprons. Taxiways and Runway are all showing and working fine after adjusting some elevations to allow for Orbx Region England.

I overcame the Runway elevation fault (patches of terrain showing through here and there) by creating a vehicle path (same dims as the Runway) underneath and now all shows correctly during Day, Dusk, and Dawn.

Night time is another matter.
At night the Runway vanishes (also the vehicle path) to leave just the airport background grass and the lights. On touch down I hear tyre squeal so it's there - just not visible. I'm using DX10 via Steve's DX10 Fixer. Switching back to DX9 does not solve the issue.

I've had a good search for possible answers and found none that would seem to fit.

Is it something obvious?

Here's hoping someone can help.

Glad to be here at last,

Ganter (Jim)
 
This runway - FS or Ground Polygon? What surface type? How wide/long?

Created from the Add Runway menu,
placed on the Airport Background Poly Flatten Mask Class ExcludeAutogen,
Asphalt,
L=3059 Metres w= 65 metres
 
Did you check the altitude of the runway vs the altitude of the Flatten?
 
The fact that you have 'bleed through' on the runway leads me to believe you do not have an FS runway but a ground poly. A true runway would flatten the terrain.
Either you have a double somewhere at a different elevation or the airport elevation does not coincide with the runway elevation.
Just an educated guess.
 
Hi, I had a load of trouble with disappearing runways and like has been said here my runway, airport and flatten background were correct I noticed a problem in map view like in this post.

http://www.fsdeveloper.com/forum/threads/disappearing-runway.440302/#post-774939

the airport hadn't reset even after moving the big airport circle in ADE, have you moved your airport at all?

If so you need to reset the radio frequencies for the airport, this can't be done by setting coordinates, you have to go to list/comms, make a note of the name, type and frequency, with the correct frequency selected(could be tower FSS, etc), delete then add new setting up as before, this seems to set things around the new airport position.

Whenever I start a new airport now I put the runway in the correct position and copy the coordinates, I then paste the coordinates to the big red airport circle thing placing it central to the runway, at this point i reset the radio comms as above.

This problem was noticeable during the day so could be a different problem but worth checking.

BTW, runways do not flatten the terrain, while taxiways and aprons do.
 
Currently on Nimitz, about to take off in the F-35 and fly back to EGVI (Greenham-Common)
I've acted on all that has been posted. Many thanks Chaps.
Wish me luck for some tarmac at the end of the flight.
 
We have a Runway at night. Combination of just redoing the Runway, then the under Runway Vehicle Path to cure the terrain fault due to Orbx Regions and Hey Presto. landed on the tarmac.
Thanks to all who posted.
 
Is a Runway centreline the correct thing to use?

Because I've just flown in to RWY 26 and the bl**dy thing's doing it again. Disappearing before my eyes as I come in (kind of rolling away to leave the grass beneath).
What am I doing wrong?

Runway paths are usually used on runways to provide AI routes. Generally ADE doesn't like non runway paths on a runway so perhaps check to see if it was changed. If it shows as a black line in ADE then it is a runway link or edit it to see
 
Right, Jon.
I should have been more specific in view of the comment that runways do not flatten the terrain.
I gathered that it would have been self evident that a runway center line would have been placed on the runway as that one does flatten things (but you still have to check if the runway itself is at the same level as the airport elevation).
I still do not understand, Ganter, why you decided to put in a vehicle path on a runway!?
 
Hi,

No, the runway center line also does not flatten terrain. You must place an apron or similar object under a runway to flatten it.

Can I post the .bgl for your perusal Boss?

I understood that it would do the trick of flattening. I'll try a centre line instead now and see how that goes.
Cheers.
 
Tom,

I stand corrected. Sorry.
But, after having taken out the vtpp and the vtpx. and having added a flatten, I see no problems at night.
