Jump to: navigation, search



Welcome to OpenSimulator version Yeti, an open-source multi-user 3D virtual environment and metaverse server platform.

If you are upgrading from a previous version of OpenSimulator, then we strongly recommend that you start off with the default configuration files and port over any changes you made to your older version of OpenSimulator.

This version is a follow up to, with a few fixes and improvements

Changes and Fixes

  • Added [LoginService] option AllowLoginFallbackToAnyRegion. With this option set to true users may be sent to any region that is online, when the requested one is not found and there are no Default or Fallback regions online. This option should only be set true on standalones or very small grids where this is not a potential privacy issue.
  • Various small changes to reduce cpu load
