You will need a 32 bit unzip utility to de-compress and install files from the net. There are many to choose from. A 32 bit file manager, such as Windows Explorer, which is part of Windows 95/98, is also necessary to move/copy files during this process.

In this case, let's say you are adding scenery for Don Mosers Webbers landing. Don puts his work into folders scenery and texture. He doesn't recurse the two folders into a third folder. This is where you'd create a new folder and call it webbers or anything you want, really. Then move the scenery and texture folder to your newly created folder. Don always includes an install file in which contains flatten switches, we'll get to that later! With this scenario you must unzip the file into a temp directory. Here is where you need to make certain that you know if your unzipped files are recursed into any kind of subdirectories.  If they are in a temporary directory on your hard drive, you can see this in Windows Explorer. Make sure that your final scenery directory is formatted like the illustration on the left. You need both a scenery and a texture folder. When you eventually add the area seen here in the select scenery box your directories will point the way for the simulator.

...	The scenery files themselves have a name extension of .bgl These contain all of the scenery code (sprite information) and drawing instructions for FS 2000 to display your new scenery. You'll also notice developers (sorry for this!!) include an exclude file.

There are two methods to install scenery into FS 2000. The first is to simply add the file path to your new scenery within the library while the simulator is running. To do this, go to the menu and select World/Scenery Library. You will see this menu. Select Add area.

You will be presented with this standard Windows file dialog box. Just locate your new directory, give the scenery area a name and select OK. You will also notice a selection asking you if you want the scenery in the cache, or if you want FS 2000 to use it directly. Your best bet is to just leave it set to Use this scenery directly.

The second method is to install the new scenery yourself via the Scenery.cfg file. FS 2000 now looks for add-on scenery, in a simple to edit text file called Scenery.cfg, which is located in the FS2000 root directory. It is here also that the flatten and exclude switches are used.

Warning!! If you do not have the correct path entered in the Scenery.cfg file, you will get an error when FS 2000 boots up!! No biggie go back and retry.

Warning!! Try not to install new scenery into an existing default scenery directory.If there is an update to the scenery you may need to do this however. 

The Exclude and flatten Switch
Exclusion and flattening switches in the Scenery.cfg file
If you add custom scenery that is designed to take the place of scenery that already exists in Flight Simulator, you must use switches in the Scenery.cfg file to ensure that your new scenery displays correctly.

For example, if you created a custom set of buildings and textures for O'Hare airport, you would need to exclude the O'Hare buildings and textures that shipped with Flight Simulator so that your custom scenery would display correctly. The instructions for using exclusion filters and flattening switches can be found below, as well as in the Flight Simulator 2000 Readme file.

Switches are added to the end of a particular scenery area entry that you create in the Scenery.cfg file using a text editor. Both switches affect only scenery areas with a lower layer number than the scenery area they are added in. For example, if the switch is placed in layer 70, then only layers 69 and below will be affected. Exclude and Flatten switches can both be added to the same Scenery area.

Flattening switch
The Flatten switch flattens a given four-sided area to a single specified elevation. This solves the problems that might occur with backward-compatible scenery due to the fact that Flight Simulator 2000 uses a digital elevation mesh terrain system instead of the flat "seed" system from prior versions.

The Flatten switch syntax is as follows:

Flatten.X=Elevation,Latitude1,Longitude1,Latitude2,Longitude2,Latitude3,
Longitude3,Latitude4,Longitude4

X is equal to a number between 0 and 9, but you must start with Flatten.0, then Flatten.1, and so on, up to Flatten.9. You are allowed a maximum of 10 Flatten switches per Scenery Area (thus the numbers 0-9).

The Elevation is in feet above or below mean sea level (msl) and can be any number between -2000 and 99999.

The Latitude and Longitude of points 1, 2, 3, and 4 must be entered in a clockwise or counter clockwise fashion about the four sided area such as:

and must be in the form of degrees and minutes. You do not need to add the * or ' symbols to indicate degrees and minutes, and the shape does not have to be a rectangle. Any four-sided shape will work.

The maximum size of a flattened area is 90 degrees of longitude and 45 degrees of latitude.

Exclude switch
The Exclude switch excludes the default Microsoft scenery (objects and/or navigational aids) in a given four-sided area from being displayed (or transmitted in the case of radio navigational aids). This solves the problems that might occur due to the fact that Flight Simulator 2000 incorporates nearly every airport and published navigational aid in the entire world and you may wish to put your own airports, navaids, or other scenery objects in place of the ones that ship with Flight Simulator.

The Exclude switch syntax is as follows:

Exclude=North Latitude,West Longitude,South Latitude,East Longitude,category

Exclusion happens only in a rectangular area such as:

You must follow the form North Latitude, West Longitude, South Latitude, East Longitude. The Latitude and Longitude entries must be in the form of degrees and minutes. You do not need to add the * or ' symbols to indicate degrees and minutes.

The category determines which default scenery type you choose to exclude in the defined area. There are 4 categories:

Objects - Excludes all default 3-dimensional buildings and objects as well as airports.
VORs - Excludes all default VOR and ILS navigational aids
NDBs - Excludes all default NDB navigational aids.
All - Excludes all default objects and navigational aids

You can use 1 or more categories in an Exclude switch.

The maximum size of an Exclude area is 90 degrees of longitude and 45 degrees of latitude.

Recap
1.) Always unzip your new file to a temp directory.
2.) .bgl files belong in the scenery subfolder ie FS2000/scenery/webbers/scenery
3.) You can put texture files in one of two directories FS2000 main or scenery local.
4.) Use the scenery config file to add flatten and exclude switches.
5.) Put static aircraft textures in your main texture folder.
6.) Always follow the developers instructions to the letter!
