# SimpleBiomes<no value>
The `SimpleBiomes` sample illustrates the process of adding biome definitions and overriding vegetation placements in Microsoft Flight Simulator 2024. Making this example required using the [Scenery Editor](../../../devmode/editors/scenery-editor/the-scenery-editor/) to generate [Polygon Objects](../../../devmode/editors/scenery-editor/objects/polygon-objects/) which are used to define the placement of the vegetation and biome in the game world. The project also includes some custom `XML` - which defines the species and biome types (see [Living World Configuration](../../../content-configuration/environment/living-world/living-world-config/living-world-configuration/) for more information).

 

 

### Loading And Building The Project

In order to load and build the project in Microsoft Flight Simulator 2024, you must have previously enabled Developer Mode ([see here](../../../introduction/sdk-overview/) for more information). Once enabled, simply follow these steps:

 

-   Use the **Open project...** command from the [**File**](../../../devmode/developer-mode/) menu. ![Developer Mode Open Project](images/7_Samples_Tutorials/general_openproject.png)

 

-   Select the file `SimpleBiomes.xml` from the `SimpleBiomes` sample project. ![Open SimpleBiomes Project](images/7_Samples_Tutorials/Samples/Scenery/SimpleBiome/simplebiomes_projectdir.png)

 

-   The **Project Editor** should open automatically and show you the project `mycompany-vegetation` (if the Project Editor doesn't open, then you can open it from the Developer Mode [**Tools** menu](../../../devmode/menus/tools/)) ![SimpleBiomes In The Project Editor](images/7_Samples_Tutorials/Samples/Scenery/SimpleBiome/simplebiomes_openinspector.png)

 

-   Selecting the project and then **right-clicking** will open a menu where you can select the **Build and Mount** option to build the project and mount the created package in the [VFS](airportkalo/#):

-   This will build a package from the files specified in your project. This package will be named `mycompany-vegetation` and will be output in the **Packages** folder created in the same directory as `SimpleBiomes.xml`: ![SimpleBiomes New Package](images/7_Samples_Tutorials/Samples/Scenery/SimpleBiome/simplebiomes_newpackage.png "SimpleBiomes New Package")

 

-   To get to the location where we've modified the biomes, simply start a free-flight at any airport, and then *right-click* on the BGL *asset group* and select **Load In Editor**: ![Edit Simple Biomes BGL](images/7_Samples_Tutorials/Samples/Scenery/SimpleBiome/simplebiomes_edit.png)

 

-   Clicking this will load the assets into the **[Scenery Editor](../../../devmode/editors/scenery-editor/the-scenery-editor/)**, and then you can double-click on any of the polygon objects listed to take you to them in the simulation: ![Simple Biomes Asset In The Simulation](images/7_Samples_Tutorials/Samples/Scenery/SimpleBiome/simplebiomes_assetingame.png)

 

-   If you **left click** on any of the polygons to select them, you can then change the biome options in the **Properties** window and see the different biomes change in the simulation, and also see listed the new, custom, biomes that the asset introduces (in this case, those listed with the `LFLJ_` prefix):
