OK ... all is working, all looks normal. I had to go in and "move to scenery.cfg" each of my 500 files (I'm a bit cross-eyed at the moment!). Went into FTX Central, they were all there on the list. I made and saved the insertion points, that worked. Went into my P3D V4 Scenery Library, everything was there, no longer grayed out and all are "active" ... (I can edit, move, etc). So Dieter comes to the rescue again! Thank you!
Bottom line ... Lorby is a great tool, but when you put things into the library using it, they are going in as xml files. These cannot be seen by FTX Central and they are grayed out and inactive in your P3D V4 Scenery Library.
If you have P3D V4, you must use version V1.18. If the entry is DARK GREEN or DARK RED, these are "xml" entries. To see them in FTX Central and the Scenery Library, you have to click on each one of them, then click on "Move to Scenery.cfg" then Submit and after you have done them SAVE!! As you move them, they turn light green. Anything Dark Red turns to sort of pink. So light green and pink mean you have the file in the scenery.cfg file.
Again, thanks to all!
