Howto:Add shared models manually: Difference between revisions

Next, locate a .stg file into which you will place a reference to the object's model and its position.  

The .stg files are named according to tile number and stored under the scenery directories.  The default installation places a limited amount of scenery (for the area around San Francisco) in <code>[[$FG_ROOT]]/scenery</code> but you may have scenery in other directories, as specified in <code>[[$FG_SCENERY]]</code>.  (See [[Howto: Install scenery]].)  Under each scenery directory, you will find directories called <code>Objects</code> and <code>Terrain</code>, and under them directories that group tiles into larger and smaller quadrants.  Thus, if the tile number is 942058, you will find <code>942058.stg</code> under <code>$FG_ROOT</code> as <code>$FG_Root/Scenery/Objects/w130n30/w123n37/942058.stg</code>.

There is generally more than one .stg file for a given tile, in different directories.  It's important to edit one that will actually be read by flightgear (see below).  One thing you can do is create a personal customized scenery directory separate from the standard installation.  That way, if you upgrade FG your customizations won't get overwritten.  If you create such a directory, list it first in <code>[[$FG_SCENERY]]</code>, create a directory structure inside it parallel to the one in the standard scenery story, and create a .stg file in the appropriate place. Similarly, it is best not to edit the .stg files in the folder where [[TerraSync]] stores the scenery it has fetched, since TerraSync may overwrite them with newer versions.  Objects associated with airports are usually put into a .stg file under a "Terrain" directory; other objects are put under "Objects".
