Map size and aprons

An apron is the terrain bits that go around the map, the scenery beyond the map edge. The Caesar 4 editor lets you choose from a fair number of map sizes; however, for most of the sizes, there are no fitting aprons available. Using an apron that is too small will make parts of your map disappear under the appron, while too large an apron will sport a (usually rather ugly) strip of water on the north and east side of the map.

It is impossible to create new custom aprons, unless you wish to invest a lot of time into it and have a 3d modelling program that can export files to the .gr2 format.

Setting the map size and apron

To set the map size, select the proper map size from the dropdown at the top of the first map. Then click on the "Reset all" button next to it to confirm the change in map size.

There are two things to note about this dropdown control for the map size:

  1. The value will reset itself to "64" when you load a scenario into the editor
  2. The value will say "64" for newly created scenarios, while the actual default map size for maps created with the "Create scenario" button is 512

The "64" in the dropdown can thus be ignored.

When you change the map size, the apron will be reset to the first one in the list. So, the proper way to set both the map size and the apron is the following:

  1. Set the map size
  2. Click the "Reset all" button to confirm the map size
  3. Select the correct region for your apron
  4. Select the desired apron

List of aprons

This is the full list of available aprons, their fitting map size and the scenario they were originally used for. The column "Water trade supported?" indicates whether the apron contains open sea or rivers, making trade by water possible. On aprons without water entry, trade by water is still possible by running a river to any map edge, but it will look odd.
