== Overview ==<br />
<br />
OpenSim.exe is the region simulator process. It loads configuration, initialises the physics and script engines, loads region modules, connects to ROBUST services, and runs one or more regions.<br />
<br />
In standalone mode, service implementations run in-process. In grid mode, service connectors make HTTP calls to ROBUST. The same code runs both ways -- only the config differs.<br />

=== Entry Point ===<br />
<br />
OpenSim/Region/Application/OpenSim.cs -- Main()<br />
<br />
-- to be documented --<br />
<br />
----<br />
<br />
=== Config Loading ===<br />
<br />
OpenSim/Region/Application/OpenSimBase.cs<br />
<br />
Same layered config mechanism as ROBUST. Reads OpenSim.ini, then config-include/ files. Architecture is selected via Include-Architecture in OpenSim.ini -- this determines whether the sim runs standalone or connects to a grid.<br />
<br />
-- to be documented --<br />
<br />
----<br />
<br />
=== HTTP Server ===<br />
<br />
One HTTP server per simulator instance, default port 9000. Each additional region adds a port (9001, 9002, etc.).<br />
<br />
-- to be documented --<br />
<br />
----<br />
<br />
=== Region Module Loading ===<br />
<br />
Region modules are plugins loaded at startup. They provide services to the scene -- asset access, inventory, physics, scripting, estate management, and more.<br />
<br />
-- to be documented --<br />
<br />
----<br />
<br />
=== Service Connector Setup ===<br />
<br />
In grid mode, outbound service connectors are loaded as region modules from config-include/GridHypergrid.ini. Each connector makes HTTP calls to ROBUST for grid data.<br />
<br />
OpenSim/Region/CoreModules/ServiceConnectorsOut/<br />
<br />
See [[OpenSimulator Internals/Connector Architecture]] for the full connector pattern.<br />

<br />
=== Scene Initialisation ===<br />
<br />
OpenSim/Region/Framework/Scenes/Scene.cs<br />
<br />
One Scene instance per region. The Scene holds all in-world state: objects, avatars, physics, scripts, terrain, parcels, and references to all service connectors.<br />
<br />
