• 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.

Extract from libraries

I am trying to convert some old FS9 sceneries to FSX/P3D. I have some of the models as separate files - no problem with those. But some models are in a library file and MCX can not access them. Is there any way to extract models from a library?
 
Hello:

Some FS9 scenery libraries utilize SCASM-compiled 3D models (not in MDL format) with conditional display code.

Depending on the individual 3D model and the conditional display code context, one may be able to still convert after de-compiling to *.SCA source code, editing, then importing the edited *.SCA file into MCX.

Tell us more about the BGL file(s) and whether they are payware or freeware, and we may be able to advise you further as to your options for conversion for use (only) on your own computer.

The bgl files are files from my own earlier scenery projects and projects I have contributed models to. Some models were made by other members of the Finnish Scenery Designers (FISD) and included as libraries in our various projects. Don't know if they are SCASM-compiled, how can I find out? I am trying to re-create some of our sceneries as FSX/P3D versions. All freeware.
 
What happens when you import these libraries into MCX? Can we get an example of one of these?
 
Unfortunately it appears you have indeed compressed the file. I tried several decompilers and they all report the file is not readable. This is great to avoid pirates, but keeping a copy of the uncompressed file becomes important at that point...
 
Ok, thanks anyway for your help! Then I know. I have to try to find the original author and hope he still has the originals. Or make new models...
 
I don't think there is any decompressor for compressed bgl files. I never found one. Luckily not that many files are compressed.
 
Hello:

Indeed as Essex states above, there is a legacy FS2000 - 2002 SDK de-compressor in the "BGLZIP" SDK component

IIUC, this is a FS2000 / FS2002-era SCASM compiled BGL which can be automatically de-compiled by BGLAnalyze version 3.1, and contains legacy format' Library-type' object placement info for 40 trees in the vicinity of Turku airport in Finland.

Chances are that such trees in the called legacy format "Library" are older uni-planar 'rotate-to-camera' tree types which, IMHO, are best replaced by FSX / P3D format, default or custom 'crossed-plane' trees placed with BGLComp-type XML 3D scenery tree objects.

The Geographic coordinates in the 40 placement RefPoints might be used as a guide for placement info. :idea:

Ok, fine, thanks. I already found the trees - they are in a separately installed common FISD library (and all cross-plane). But looking closer at my project it turned out that parts of the airport have changed so much that I have to place trees and stuff from scratch anyway. So there is no use for the old placement info...
