"Acropolis"-effect at KLAS

(1/13) > >>

Bert Groner:
Hello all together!

Congratulations to the whole FSDreamTeam for releasing the long awaited KLAS. It clearly seems to be a very well done successor of simFlyers version issues a long time ago for this prominent airport.

The only thing should corrected on my point of view is the hugh "Acropolis"-effect which is conspicious with FS 2004 (not tested with FS X right now) from the middle of the scenery to their western boundaries. As Umberto told me already that this is not a problem of the scenery cause it has got the right elevation but not the mesh-add-on "FS GLOBAL 2008 X" (for FS 2004 and FS X) I use.



But as the makers of this (and I guess this counts for other meshes as well) mesh are telling methat their product has got the correct elevation as well I suggest and hope that "Andydigital" should dive into that please as he have done this succcessfully with Geneva before:

Thanks in advance!

Just to be more precise: the issue is not the mesh being "wrong" or not precise enough. Instead, is exactly the opposite: it's *because* the mesh is "right", that the scenery shows this effect.

The reason is, the real world KLAS (as many airports in the world) is not flat across all its area, there's a 100 ft elevation difference, for example, between the east/west side of Rwy 25.

But, since FS9 or FSX don't support sloped airports and runways, the airport has to be flatten to the elevation of the published QNH. This will create a visual difference in areas were the flattened airport meets with the mesh, which is of course similar to real world so it IS sloped.

The default meshes from MS had some pre-processing, that smooths the mesh in an area 1-2 km around every airport, so the visual effect do not get noticed, but this technique is not always used by mesh authors, that's why the effect is more visible with 3rd party meshes.

Of course, this issue is more relevant to FS9, were the use of 3rd party meshes is basically mandatory. Since FSX already use SRTM 90 m meshes by default (at least in the US and Europe), and this mesh HAS been pre-processed as explained above, the effect is far less obvious in FSX.

Bert Groner:
Understand, Umberto, thanks!

So hopefully "Andydigital" will find time to take care of that issue fo the sake of FS-2004-users...

Best for now!

Bert

P.S. Another idea might be to extend the "Acropolis"-effect into the deep vincinity so that is no more noticable while approaching KLAS. What do you think about that?

AaronMyers:
I was about to post about the same issue. It's so dramatic that the far corners of the ground textures actually hang over the cliff.

virtuali:
The issue is that in FS9 it might be more tricky to create a mesh fix, because you need to create a whole LOD for the mesh, while in FSX is possible to create a very small local mesh instead.
