I have followed all the instructions hence still noolaero vdgs doesn't work in EGLL. There is no file "noolaero-vdgs-egll" from inibuilds-airport-egll-heathrow\SimObjects\Landmarks\ - making it instead "noolaero vdgs egll". There is inibuilds-vdgs-egll on which I removed the dashes and run the MSFSLayoutGenerator. I have the latest scenery from Inibuilds, Premium version 1.0.8 for MSFS 2024. Noolaero works fine in other airports such as KLGA, CYUL. Not sure why it doesn't work for me.
