The steup dialog allows access to parameters which are essential for locating ADD-ON FS sceneries.

| Name | Description | Min | Max | Default |
| Scenery.cfg | A file which tells FSImp where to look for any ADD-ON FS sceneries.
The scenery.cfg file contains information on available ADD-ON sceneries. The path of this file is used as the FS main folder and also locates the common
FS TEXTURE and AIRCRAFT sub folders. FSImp allows you to use a file with any name and folder location.
If you have any version of MSFS installed then use the Browse... button to locate this file which is in the main MSFS folder. This can be used directly and should need no special modifications for FSImp. If you do not have any version of MSFS installed then use the NOFS button to locate the example file which is in the X-Plane...\Resources\plugins\FSImp\NOFS folder. This is a sample with two simple demo areas - a few generic buildings near EIDW and KSLC. It gives you an idea of the syntax for ADD-ON sceneries and may be used for adding new ADD-ON sceneries. See sceneries Alternatively you can use the Browse... button to locate a scenery.cfg file that you have created yourself. Should the Browse... button not work, for some reason, then you can type in the full filename for your scenery.cfg file. | |||
| User key | A personalized software key which switches FSImp from demo to normal mode.
This software key looks like FSIMPversion,name=number. Please note the following: Keep your personalized software key safe as it may be needed again Note that if the demo mode timeout has been reached and you enter a valid key, then FSImp will run in normal mode next time X-Plane is started. See registration | |||
| Air FPS | FSImp attempts to maintain this FPS rate when in the air (flying). Too small makes flying unresponsive, too large may not be attainable and sceneries will not be displayed. | 16 | ||
| Ground FPS | FSImp attempts to maintain this FPS rate when on the ground (taxiing etc). | 12 | ||
| Scenery density | The scenery density can be selected between very sparse and very dense, or auto. Each ADD-ON FS scenery decides for itself which models to show depending on the scenery density. When Auto is selected FSImp dynamically sets the density depending on frame rates. | v.Dense | ||
| Traffic Active % | Controls what percentage of flight plans, from traffic files, are to be activated | 0 | 100 | 100 |
| Advanced Menu | Allow an advanced plugins FSImp menu. Most FSImp menu items are blanked out when this option is not selected. | no | yes | yes |
