Brief description of the issue:

Some modeled traffic is sometimes invisible. I have provided screenshots of one, but there were several invisible at the time. Checking Developer Mode Debug, there were currently 122 aircraft simobjects - maybe exceeding some limit?

Provide Screenshot(s)/video(s) of the issue encountered:

In this screen shot AAL1429 is invisible except for the Taxi Light reflection.

If you move away and come back later, AAL1429 is no longer invisible.

The aircraft navigation lights were visible on both aircraft in the screenshots below. It seems that there is no texture mapping for the B789 & C680, so they are transparent.

This was at Suvarnabhumi Intl (VTBS), 02/26/24 (build 1.37.4.0):
Repro - Modeled Traffic Is Sometimes Invisible @ Suvarnabhumi Intl (VTBS)

and at Phoenix (KPHX) 03/08/24 (build v1.37.7.0):

had the same thing happen at KJAX this evening like the modal was missing but the tag was ‘flying’ like normal

Still seeing (or rather not seeing, ha!) invisible aircraft. I just followed a C172 as number 2 for landing at KSBP, only it was invisible. I had to turn on nameplates to “see” it.

Same happened to me yesterday in LSZH

I suspect this is some kind of connection management to not overwhelm SimConnect.

What I see on the map:

Is not what I see out the canopy:

Invisible airplanes are very pervasive for me.

Airplane lighting does show and sounds. I made a report on having so many invisible airplanes with their beacon lights on that it looked like a fire department response was occuring.

Sometimes the invisible airplanes are also of the upsidedown spinner variety.

I believe this is a SimConnect/SimObject limitation issue that has been around forever! Not sure if Asobo is able to fix this as it has been brought up many times in the past! It’s good to keep bringing it up and see if it will ever gets fixed!

You mean the same thing where you will get your start airport empty when coming back after turnarounds? This has ruined a lot of this sim for me, since turnarounds is a big part of daily airline operations. Cannot belive they have not manged to fix this yet :grimacing:

Yep! Same issue! Somehow I haven’t had that issue in the past few months, but yes, it’s the same!

Empty with a big light show of invisible, upside-down airplanes spinning around.

I do quite a bit of real-life, student type flying. I’ll go out and do a few touch and goes at another airport and come back to the origin. That’s when things can get weird.

I get it every single time. Have you made any changes recently that might make it work for you sometimes?

Not really! I am not sure what happened but after Sim Update 13 or 14 it started working for me again! It’s stuttery but works. Have you tried changing the number of clients in SimConnect document to 128 instead of 64? That may help…

I see. Nope, I was not even awere that was a thing. Thank you so much for the tip, Im willing try anything at this point. At least until BeyondATC comes out with traffic

Yeah, it’s a frustrating issue! Hope it gets resolved. Good luck.

Is that for invisible airplanes or no airplanes?

Potentially! Try it and see if it works …
