Weirdly I reloaded the scenery without any traffic (aircraft), and didn't see any floating cones anywhere, so not sure if it's connected to having aircraft enabled, or maybe GSX if that has an input?

On the main menu, select Marketplace. In Marketplace select My Library, then search for EGLL, and then disable it.

I disabled the default EGLL and have restarted the sim a few times and it has remained disabled. I do run the sim with admin rights, not sure if that may help?

I'm not seeing that, do you have photogrammetry on? I am seeing a few minor mesh errors though.

Thanks, didn't spot the dual scenery. I disabled the default scenery, deleted the rolling cache, but still seeing the odd floating cone, but they turn up in random spots. Also spotted a few other minor issues.

Scenery looks great so far, just spotted this ...

I did a couple of high speed taxi checks (80 -100 knots) along 13L/31R, and did notice a slight bump around this area that made the aircraft move around, but not enough to cause me to crash, weird how it affects some people more than others. Obviously this is not ideal, the runways and taxiway's should be flat, hopefully the developers will carry out taxi and take off checks of their own.

I had a quick look and can't see any bumps on 13L/31R runway (although I just used the external camera and didn't taxi or try landing on it). Are you using GSX? There is an interesting post here if you are. Troubleshoot - GSX Causing Bumpy Terrain, Double Parking Spots & Broke – Macco Simulations

I use addon linker and have not had any problems in the past, weird.

The only thing I can suggest is to temporarily remove ALL addons from the Community Folder, start MSFS, turn Rolling Cache on, physically delete any rolling cache and turn it off, then close MSFS. (I know you mentioned that it's not turned on, but there could possibly be an old cache present). Delete any scenery indexes (I know you mentioned that you had already done that, but do it again), do a fresh install of the Luton Scenery (do not put any other addons in your Community Folder) and then start MSFS. In options, just make sure the Bing Data and photogrammetry is turned on, I've had the odd occurrence of them turning off, and see how you get on.

Do you have photogrammetry turned on?

You could try deleting the contents of the SceneryIndexes folder

Do you have Bing Data and Photogrammetry turned on in the MSFS options?

Seems to be working okay for me now

Same issue here

I don't have this scenery, so can't test it myself. In general, if I have had terrain problems, I have found that having Bing Data and Photogrammetry turned off can cause these issues, and also clearing out Rolling Cache and the SceneryIndexes can sometimes help.

Do you have Bing Data and Photogrammetry turned on in the MSFS Settings?

Okay, I got mine directly from IniBuilds, but is showing the same 1.0.3 version. Good luck with the troubleshooting.

I'm seeing some differences to my scenery. May I suggest that firstly check that you have the latest version. Then remove ALL other addons from your Community folder, and do a fresh install of KDTW so that just KDTW is the only addon in your Community folder and check the issue. If that doesn't work, maybe delete your Scenery Indexes and Rolling Cache to see if that works.

I'm not seeing that, have you uninstalled Asobo's KJFK?

If I were you, I'd remove EVERYTHING from your Community Folder, start MSFS, clear out the Rolling Cache and close MSFS. Do a fresh install of the airport (no other addons), and start MSFS to see if you still have the issue. If you don't, start installing other addons to see if any of those are conflicting with the scenery.

It's in the General Options - Data - Photogrammetry within MSFS

Have you tried removing everything from your Community folder, and doing a fresh install of the scenery? Also, check that Bing Data is turned on.

Standard thing (other that what is already been suggested) is to remove EVERYTHING from the Community Folder other than the PHNL scenery. Start the sim, clear/delete any rolling cache, then restart the sim, check and report back.

Having been to that area on a couple of occasions, I was surprised and happy to see the Inibuilds email regarding the Corpus Christi airport. However, I still find it a shame that developers seem spend MORE time on modelling and texturing the interiors of an airport for a FLIGHT simulator (understandable for a passenger simulator) than the concentrating on the exterior airside area's where the aircraft are.
