• 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.

Runway polygon flickering

hello everyone,

I've been playing around with the tutorial about Creating High-Detail fs ground polygons, got it good until the part where I have to tweak the ASM files.... for some reason my ASM files do not have the same text as the tutorials. Here's the example:

Tutorial:

The first tweak is opening rwy_base.asm using notepad and finding this entry:

OBJECT_0_START label word


IFIN1 OBJECT_0_FAIL, image_complex, 1, 32767


ADDOBJ OBJECT_0_SCALE


SHADOW_CALL OBJECT_0_SCALE

To get rid of the shadow and create a true ground poly, I change it to this:

OBJECT_0_START label word


IFIN1 OBJECT_0_FAIL, image_complex, 1, 32767


ADDCAT OBJECT_0_SCALE, 8

I deleted the SHADOW_CALL line altogether, changed “ADDOBJ” to “ADDCAT”, and gave my poly a layer number by including “, 8” after OBJECT_0_SCALE. I usually make my base layer number 8, then increment in multiples of 4 as a add layers. Higher layer numbers display over the top of lower layer numbers without flickering.

--------------------------

Mine:

Can anyone help me on that please?
Thanks

Nick,

You used the FS2004 gamepack to export your ground polygons, but to be able to apply the tweaks you need to use the FS2002 gamepack. This produces different ASM code structures.

If you do not have the FS2002 gamepack, you could also capture the FS2004 X file and run that through the FS2002 MakeMDL. This Wiki article describes that process.
 
Thanks Arno,
It's working now.
But I have another problem, now the custom runway isn't showing in FS now, can you tell me how to flatten the whole default airport?
and I have another question, is there a forum link where I can find a tutorial on how to add lights to the runways?

Thnks
Nick

Are you making it for FS2004 or FSX? For FS2004 I would use SBuilder to make the flatten, for FSX SBuilderX or ADE are good choices. Btw, without a flatten you should still see part of your polygons. If you see nothing at all something else might be wrong. For example you entered the wrong coordinates during the export.

I don't think we have a tutorial about that on the Wiki, but in the forum you will find many threads about this subject.
 
Thanks arno for replying,
I'm doing it for FS2004, I downloaded Excbuilder, but since you metioned Sbuilder, I'll download that one too.

Is it possible to create a new layout in AFCAD then overlay custom ground textures on the airport?

Nick
 
Hi Nick,

No, the custom ground polygons will always be on top of the AFCAD airport layout, there is no way to reverse that.
 
Thanks arno for the answer.

by the way, is there a tutorial on how to use the sbuilder? i'm a lil bit confused x)

thnks

Nick
