I am currently having an issue with all aircraft except PMDG and Fenix.  All other aircraft including A2A Comanche and the Aerosoft CRJ are effected.  The issue is that all the external lights from the taxi light, landing lights, even logo light.. Do not illuminate outwards as they used to.  You can see them on when you switch to the external views but they do not illuminate the area in front of them.  I do not have any lighting or effects mods, haven't changed any config files.. I run Windows 11 on the PC and everything works fine except for this.  I am running into a brick wall because I cannot find any other recently publicized information about this.  This is some sort of an "effects" issue that has arisen after SU15 I am sure.  I notice a lot during the night time hours because that's primarily when I fly the most.  Has anyone else noticed this or can test for it? 

 

I had a similar issue some weeks ago and after spending almost 3h to find the causing addon, I finally found the A2A Comanche to be the culprit. Happily, a simple reinstallation of the A2A Comanche fixed the issue, so give this approach a shot.

Yes.  I decided to uninstall and reinstall the Comanche also yesterday.  Didn't work, the issue still perisists.  Its as if the landing lights effects are pointed straight upwards instead of along the plane of the aircraft as they should be.  It's weird.  I've tried going to the MSFS forums but its such a mess there and I cannot even create a topic there because apparently i'm not popular enough yet with the algorithms.  Who knows.  It's not just the Comanche, it was the same on the Aerosoft CRJ last night also.  Even the logo light was pointed straight up.  The light originates between the engine cowlings and points straight up, missing the vertical stabilizer where it's supposed to shine on.  

Ok, then you have another addon that is messing with the .fx files of the sim. Sadly, it seems that you must go the same route I did: move 50% of all addons to a separate folder and test. If the issue persists, remove 50% of the remaining addons and test. And so on. the moment the issue is fixed, you might have a relatively small number of addons causing the issue. 

Of course, this approach only works if the issue does not exist with an empty community folder. Did you test this once?

No. I have no idea where to begin with something like that. I rarely have any issues at all.  This is a first for me.  I am currently sending a report to Asobo with some screenshots and information.  I dont have anything except payware aircraft and airport sceneries.  Again, does not effect Fenix or PMDG. just everything else.  So i'm thinking pmdg and fenix had a fix for this.  I will let you know if and when Asobo responds with anything to me.  I just don't have the time go thru a huge process of elimination moving files around and such.
