Since P3D v3 I had installed most of my sceneries outside the P3D root folder (even on an extra drive) and point to these outside folders with the HardLinkShell Extension (which basically creates a virtual link from the P3D main folder to the outside folder). Works flawlessly.
So, I would like to keep my FT sceneries in that outside folder and patch these rather than re-installing them into P3D v4 (which would then point to the same outside folder location). Of course applying the patch itself works perfectly, however, for instance the SmokeFX in Toronto don't work and in Amsterdam I had elevation issues following that procedure). After a complete re-install these worked. So, I assume, if there are files that the (original) installer had copied to any other folder than \Prepar3D v3\FlyTampa (i.e. into any of the standard scenery folders) then this process will not work, and I would indeed have to re-install everything into P3D v4.
Hence the question: Are there any sceneries that install anything outside the \Prepar3D v3\FlyTampa folder?
Many thanks for your patience with us and your great support
