Disappearing AI in Honolulu FSX

(1/4) > >>

tetchan:
I read somewhere on previous older posts that says you must remove aircraft shadows in order to see non-FSX aircraft and that is because FSX does not show non-FSX aircraft in airports with customized textures.  What distingushes a FSX aircraft from a non-FSX aircraft? Is it it's texturing, model, air files?  What customized texuring does FSDT Honolulu FX have that makes non-FSX aicraft invisible with shadows activated?

virtuali:
What makes an AI model an FSX native model, it's the .MDL file, which should have been created using the FSX SDK. When seen with an hex editore, the beginning of the file will contain the MDLXMDLH string, compared to FS9 models, which will contain the MDL8MDLH string.

FS9 models are not compatible with airports which uses custom runway textures, unless you turn "Aircraft cast shadows on ground" OFF. Beside, since FS9 AI models in FSX are heavier on fps than native ones, you would probably want to turn off airplane shadows anyway...

Hi all,

I also have the problems with the WOAI  AI traffic disappearing in fsdt-LSZH and fsdt-PHNL sceneries when the aircraft shadow is on, but not with fsdt LSGG! This is strange. I now changed LSZH fsdt into FreeZ Zurich live and the problem is solved. But what with other fsdt sceneries?

Can anyone tell me what to do? to uninstall the shadow is a great pity. Is there a difference between "myTraffic2010" and WOAI (WOAI offers both fs9 and fsx installation, but even fsx installation does not solve the shadow problem with fsdt)

Thanks a lot for your help

Best regards

Alfred

As explained in other threads, the problem is caused by using AIs made for FS9 into FSX which is both slower than using FSX native models, and creates this problem but ONLY at airports which are using custom runway textures+lights, LSZH has them, LSGG does not. If an airport uses default runway textures, even FS9 AI models will display. Of course, an LSZH representation without its particular runway texture, loses a lot of realism. Most of our airports have custom runway textures.

And, in any case, by using FS9 AI models in FSX, you are getting worse performances anyway.

So, either you turn off the "Airplane Cast Shadows on Ground" option OR you use a proper FSX traffic package in FSX, instead of one ported from FS9. The fact that a traffic package has an "FSX install", doesn't make it FSX native. See my previous message how to identify a proper FSX model.

I believe that both MyTraffic 2010 and Ultimate Traffic 2 use native FSX models, but surely WOAI does not, for the most part.

petakas:
Unfortunately I have the same problem.
Switching shadows OFF is for me unrealistic and also on each Display Settings update the texture resolution setting goes to 1024 and then I need to manually change it to 2048 or 4096.

I found this thread though on the issue at the FS Developer's forum.

User BrBlazer explains that it is related to RUNWAY LIGHTS being compiled by SCASM and also provides a solution.


--- Quote ---Yep. Avoid using SCASM code. I know we love easy scasm code for runway lights, papis and stuff, but FSX post-SP2 doesn't which is a shame.

There are 2 solutions that I know of: Model your runway and it's lights in gmax with BGLLIGHT, or cut a whole in your ground poly to show the AFCAD runway bellow.

--- Quote ---The fs2002 gamepack poly is still good, as it's code compiled by bglcomp.exe, not by scasm.exe.

The invisible runway is the one that causes it. If you remove that bgl from the scenery folder, you'll see the aircraft in the day with shadows on.

Question to Umberto:
Is it so hard to change this to the above solution with an update so that we have certain AI planes not invisible ?
