Hello:
AFAIK, you appear to be trying to further modify FSX local display of this add-on scenery:
Algiers Real Scenery X (aka "AlgiersX 2011" cited in the OP above)
http://library.avsim.net/esearch.php?DLID=159368
IIUC, the above add-on scenery is intended to modify FSX local display of another scenery:
Algiers City X - PhotoTerrain FSX scenery
http://library.avsim.net/esearch.php?DLID=159367
FYI: These scenery packages were made via a curious (
but interesting ! ) mix of legacy FS2Kx and FSX SDK methods / files.
As a minimum, you 'may' need to:
* Disable a legacy format (BGLC-compiled) 'Exclude'-type BGL:
[DAAGRealSceneryX install path]\Scenery\vtpexclude.bgl
UPDATE: This BGL does not exclude Autogen

; This file contains terrain data of textured polygon type

* Create your own custom photo-real aerial imagery BGLs via FSX SDK Resample using blend masks and specific LODs which allow for super-imposed display of your scenery on top of the underlying custom photo-real aerial imagery from:
[AlgiersCityX install path]\Scenery\0130020332_13.bgl
[AlgiersCityX install path]\Scenery\0130020332_13lm.bgl
[AlgiersCityX install path]\Scenery\0130020333_13.bgl
[AlgiersCityX install path]\Scenery\0130020333_13lm.bgl
* Decompile the 461 *an.AGN files mapped to the above scenery photo-real BGL and merge their data with your own autogen annotation data, then output new 1-piece "hybrid" *an.AGN files under their original FSX location-specific file names ...which you can then annotate (IMHO 'properly') using FSX SDK Autogen Annotator.
Alternatively: with your own custom photo-real aerial imagery BGLs created via FSX SDK Resample loaded (but the above cited "AlgiersCityX" Scenery
NOT loaded / not 'active':
1.) Copy the 461 *an.AGN files from the [AlgiersCityX install path]\Texture folder
2.) Place those 461 copied *an.AGN files into the \Texture sub-folder paired with your
own \Scenery sub-folder containing your custom photo-real aerial imagery BGLs
3.) 'Annotate' your
own custom photo-real aerial imagery BGLs using FSX SDK Autogen Annotator
FYI: This may edit and update your
copies of any *an.AGN files from the AlgiersCityX mapped to your own custom photo-real aerial imagery BGLs ...which
do over lap with those specific LOD-13 scenery tile areas already covered by the AlgiersCityX custom photo-real BGLs.
[
EDITED]
NOTE: Any annotations you perform on your working
copies of the 461 *an.AGN files (from the [AlgiersCityX install path]\Texture folder) which were placed into your
own project \Texture folder ...will be intended to
replace those original *an.AGN files from the [AlgiersCityX install path]\Texture folder.
Thus, when you are finished doing your Autogen annotation for your
'own' photoreal scenery, the
'original' 461 *an.AGN files from the [AlgiersCityX install path]\Texture folder should be
disabled (by
ex: moving them into a *.ZIP file inside that same original folder).
This is necessary because, IIRC, FSX can use only (1) such specifically-named *an.AGN file mapped to a specific LOD-13 scenery tile area at a time when a FSX Resample SDK 8-bit Alpha channel 'Blend Mask' source file is configured via gray scale value transparency thresholds to blend (2) or more custom photo-real aerial imagery layers into one another (...so that underlying photo-real aerial imagery layers and any locally-mapped Autogen is allowed to
show through to the layers above).
[
END_EDIT]
BTW: 'New' *an.AGN files will be created by FSX SDK Autogen Annotator for any LOD-13 scenery tile areas which do
not over lap with those specific LOD-13 scenery tile areas already covered by the AlgiersCityX custom photo-real BGLs.
CAVEAT: This project will require some rather complex techniques and study.
Hope this helps with the learning process !
