• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Edit Object Placment BGL

So I have an airport here, and there a couple library bgl files and a few object placement bgl files. I want to remove or reposition a couple of these objects. How can I do that?

I know that it can be done by using Instant Scenery but that is tedious -- first you have to guess which placement file it is that you need to modify and doing that takes time, since you are doing it 'in game'.

Is there any tool out that that can at least read the contents of an object placement bgl file? Is there a way to decompile it into a readable format? At least then I know what file to work on, if there is no other way but to use Instant Scenery to modify it.

Hello:

Instant Scenery version 2 (aka "IS2") or version 3 (aka “IS3") offers a couple of ways to visually identify "objects from all scenery files" in a specified radius near the user aircraft via display of colored text info on-screen at run time for BGLComp-XML-placed objects in a scenery object placement BGL; thus, one does not need to "guess which placement file it is that you need to modify", or to 'decompile' a placement BGL. ;)


NOTE: Whether or not a XML scenery object placement BGL was made by IS3 won't matter, as those BGLs made via other methods such as either FS9 or FSX BGLCompiler... can normally also be opened by IS3.

So, even if a (non-IS3) XML scenery object placement BGL has been decompiled, edited, and and re-compiled via FS9 or FSX SDK BGLComp, it can again be opened by IS3, and used to place more objects.


IS3 can ID those Objects, Generic Buildings, and Exclusions "placed" near the current aircraft location from ALL scenery files which are 'active' in FS within a number of miles specified for the IS3 object labels "scan" radius.


Identify objects in IS3 “Move / Delete Objects” mode


In FSX free-flight mode using any aircraft at the scenery project airport:

Set FS "camera" view to Top-Down or Virtual Cockpit without instruments displayed at desired Zoom level

1.) Slew aircraft to (minimum of) 50 to 100 feet AGL

2.) Open IS3 from FSX main menu > Add-ons > Instant Scenery

3.) On the IS3 main menu, click on the ‘Folder icon’ (Open Scenery) and "Open" your scenery placement BGL in question

4.) Back in FSX, right-click the ground, and click to ‘check’ “Move / Delete Objects”

5.) Again in FSX, right-click the ground, and click “Labels”, then click to ‘check’ “All Objects”

6.) Once more in FSX, right-click the ground, and click “Labels”, then click to ‘check’ “Library and Model”

7.) Back in FSX with IS3 still open, move the mouse cursor over objects to select them (mouse-over)


NOTE: When selected by a ‘mouse-over’, scenery objects in the currently “open” IS3 or other XML scenery object placement file... will display their bounding box, and their corresponding library and model name will be highlighted on-screen.




An alternate method may also be used to scan multiple IS3 or other XML scenery object placement files all at one time: :idea:


Identify objects in IS3 “Show Objects From All BGLs” mode

In FSX free-flight mode using any aircraft at the scenery project airport:

Set FS "camera" view to Top-Down or Virtual Cockpit without instruments displayed at desired Zoom level

1.) Slew aircraft to (minimum of) 50 to 100 feet AGL

2.) Open IS3 from FSX main menu > Add-ons > Instant Scenery

3.) In FSX, right-click the ground, and click “Labels”, then click to ‘check’ “All Objects”

4.) In FSX, right-click the ground, and click “Labels”, then click to ‘check’ “Library and Model”

5.) In FSX, right-click the ground, and click “Extras”, then click to ‘check’ “Show Objects From All BGLs”


NOTE: From the latter context menu, a “Objects From All BGLs” dialog pops up

6.) In the “Objects From All BGLs” dialog, click to ‘check’ “Objects”, “Gen. Buildings”, and “Exclusions”

7.) Still in“Objects From All BGLs” dialog, click in “Radius, NM” to set a Ex: (1) nautical mile radius; click “Scan”


IIUC, after the BGL scan is done, IS3 should identify on-screen, "ALL" default FS and 3rd party XML-placed scenery objects 'active' in the FS scenery library... for that geographical area (within a Ex: 1 mile radius of the aircraft) at the scenery project airport.


Hope this helps identify the object(s) in question ! :)

On it right now, Gary. Thanks for this lengthy write-up. Perfect for the slow kids around here, like me.
