• 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.

Geolock 1.1

When compiling a scenery .bgl file for Microsoft Flight Simulator or Prepar3D, the compiler examines each entry that positions an object and places some code in the file header that defines the geographic coverage of the placement items. In this way, Flightsim needs only examine the file header to determine whether there is anything in the file relevant to the current position of the user aircraft. This, in turn, reduces processing overhead because unneeded (relative to the user aircraft position) objects and positioning data is not loaded. The file is considered geo-locked to its coverage area.

But, there’s also a “downside” to this scheme. If the file contains any objects that might be useful outside the area to which it is geolocked, those objects are not accessible. Further, library object .bgls (which contain only object model data but no positioning data) are not geo-locked by the compiler. Hence, objects in such files are always loaded, whether or not they are needed. To address this latter situation, Microsoft geo-locked some of the stock libraries (e.g., Scenery\Orlando.bgl) when developing Flight Simulator. But, this capability is not supported by the released compilers.

Geolock to the rescue! GeoLock is a utility which allows you to:

  • unlock geo-locked .bgl files,and
  • create geo-locked or unlocked subsets of models contained in scenery and object library .bgl files irrespective of whether the source bgl was geo-locked or not.
    In addition, GeoLock can display a 3D image of each model in a file. So, it is also useful in examining the models contains in an scenery object library.
