[edit] OpenSimulator 0.9 and later

By default, regions are configured in a file named Regions.ini in the bin/Regions directory. If you started a completely fresh installation of OpenSim, it will ask you a series of questions to set up your first region.

Here's an example of a Regions.ini file

[Big Fat Region]
RegionUUID = 5ce85740-6460-43d3-ba4c-29207b010072
Location = 1000,1000
InternalAddress = 0.0.0.0
InternalPort = 9000
AllowAlternatePorts = False
ExternalHostName = mymachine.something.org
SizeX = 512
SizeY = 512

This is a list of settings that must be present for a region to operate. When you start OpenSimulator for the first time without an existing Regions.ini file, you'll be asked for an entry for each setting in order to set up your initial region. For more details, see Configuration#Running OpenSimulator for the first time.

Attribute Description
[Big Fat Region] The name of the region.
RegionUUID The unique ID of the region.
Location The (x, y) location of the region on the grid.
InternalAddress 0.0.0.0 if you have more than one NIC on the server and you don't care which IP address OpenSimulator listens on (this is the usual setting). Alternatively, you can set to a specific IP.
InternalPort IP port for all incoming client connections.
AllowAlternatePorts Not Used. Leave it always False.
ExternalHostName External IP Address of the router or FQDN. (must be the same for all regions on file)
SizeX and SizeY The region size, must be a multiple of 256, and equal. If not present will be 256m

If you want to add another region you can

  • enter another section in Regions.ini
  • create another separate .ini file in bin/Regions
  • create an old format OpenSimulator xml file (these still work with current OpenSim)
  • or use the create region command on the region console (I don't recommend this since it seems to be a bit buggy).

Here's an example where a second region has been added to Regions.ini

[Big Fat Region]
RegionUUID = 5ce85740-6460-43d3-ba4c-29207b010072
Location = 1000,1000
InternalAddress = 0.0.0.0
InternalPort = 9000
AllowAlternatePorts = False
ExternalHostName = mymachine.something.org


[Greek Wedding]
RegionUUID = 5c445740-6460-43d3-ba4c-444444445555
Location = 1000,1001
InternalAddress = 0.0.0.0
InternalPort = 9001
AllowAlternatePorts = False
ExternalHostName = mymachine.something.org

As you can see, the Second region is named Greek Wedding and has a different UUID. It has a different location (1000,1001) and a different InternalPort (9001). Other than that, the details are the same.

To create a new UUID you can either tweak an existing one by hand (e.g. by changing one character so that the new one is in the range [0-9][A-F] or a generator can be found at uuidgen webpage. On Unix, you can also use the uuidgen command.

As well as the critical entries above, there are some additional optional ones that can change the properties of a region. These are

Attribute Description
MaxAgents The maximum number of agents that can be in the in the region at any given time. The default is 100. As of 4/22/2011 this option only exists in the current git master.
MaxPrims The maximum number of prims that the region will be listed as supporting. However, this limit is not currently enforced by OpenSimulator. Due to LL protocol constraints, the maximum limit that can be shown is 45000.
PhysicalPrimMax The maximum dimensions of a physical prim. This is a single number which applies to X, Y and Z co-ordinates. This will affect resizing of existing prims. Default is 10. This setting can also be used in the [Startup] section of OpenSim.ini. If the region setting exists then it will override the OpenSim.ini setting.
NonphysicalPrimMax The maximum dimensions for a non-physical prim. This is a single number which applies to X, Y and Z co-ordinates. This will affect resizing of existing prims. Default is 256. This setting can also be used in the [Startup] section of OpenSim.ini. If the region setting exists then it will override the OpenSim.ini setting.
ClampPrimSize If true then if a viewer attempts to create a prim which has any dimension larger than the NonphysicalPrimMax, then that dimension is reduced to NonphysicalPrimMax. Default is false; This setting can also be used in the [Startup] section of OpenSim.ini. If the region setting exists then it will override the OpenSim.ini setting.
RegionType The region type as shown in the Covenant tab of the Region/Estate dialog in a standard Second Life viewer. Can be used to specify Mainland, Estate, etc. based on type of grid.
MaptileStaticUUID UUID of texture to use as a maptile for this region. Only set if you have disabled dynamic generation of the map tile from the region contents.

[edit] Other Tasks

[edit] Configuring Multiple Regions on a Single Server Instance

To configure multiple regions on one server (i.e. a 4x4 server), edit the Regions.ini file to include multiples of the single entry already there. Make sure the RegionUUID and InternalPort are different on each one, or it won't work. To load individual OAR files into each region, use the 'change region [regionname]' command and then 'load oar [oar-location]'.

[edit] Loading from the web

OpenSim.exe can read the region definitions from the web using the following settings :

   [Startup]
       region_info_source = "web"
       regionload_webserver_url = "http://example.com/regions.xml";

The following format has been reported to work with OpenSimulator 0.8.* :

   <Nini>
    <Section Name="My region Name">
      <Key Name="RegionUUID" Value="4208aa66-ce9b-4f49-a4da-06a27d95f001" />
      <Key Name="Location" Value="7000,7000" />
      <Key Name="InternalAddress" Value="0.0.0.0" />
      <Key Name="InternalPort" Value="9016" />
      <Key Name="AllowAlternatePorts" Value="False" />
      <Key Name="ExternalHostName" Value="mygrid.org" />
      <Key Name="MaxPrims" Value="15000" />
      <Key Name="MaxAgents" Value="40" />
      <Key Name="RegionType" Value="0" />
      <Key Name="SizeX" Value="256" />
      <Key Name="SizeY" Value="256" />
      <Key Name="MaptileStaticUUID" Value="00000000-0000-0000-0000-000000000000" />
    </Section>
   </Nini>
