Mobius is discontinued. Please instead use our successor fork Consortium

This is our public version of Mobius. Features will be added here once they reach a relatively stable stage in their development.

Features will be developed on their own branches that are based on master until they are ready for beta. Small patches and changes will go straight to beta. The beta branch will always be up-to-date with master. Once the beta branch is stable it will be remerged into master. In short, master is the stable release, but beta will have more stuff.

Beta 1.4.2

+ Added support for the additional info on the top scripts floater
* Updated prebuild to support vs2019
* Updated .gitignore to core's
* Fixed a minor issue with os_groups_Store.migrations

Beta 1.4.2 Notes:

  • I haven't done the additional filters yet for Top Scripts

Mobius inherits the following from osCore2:

  • phpmutelist is included by default
  • YEngine (formerly XMR) is included and is the default script engine
  • Bulletsim has been removed and UbODE is the default physics engine

OpenSim Overview

OpenSim is a BSD Licensed Open Source project to develop a functioning virtual worlds server platform capable of supporting multiple clients and servers in a heterogeneous grid structure. OpenSim is written in C#, and can run under Mono or the Microsoft .NET runtimes.

This is considered an alpha release. Some stuff works, a lot doesn't. If it breaks, you get to keep both pieces.

Compiling OpenSim

Please see BUILDING.md if you downloaded a source distribution and need to build OpenSim before running it.

Running OpenSim on Windows

You will need .NET 4.6 installed to run this version OpenSimulator.

We recommend that you run OpenSim from a command prompt on Windows in order to capture any errors.

To run OpenSim from a command prompt

  • cd to the bin/ directory where you unpacked OpenSim
  • run OpenSim.exe

Now see the "Configuring OpenSim" section

Running OpenSim on Linux

You will need Mono >= 5.x to run this version of OpenSimulator. On some Linux distributions you may need to install additional packages. See http://opensimulator.org/wiki/Dependencies for more information.

To run OpenSim, from the unpacked distribution type:

  • cd bin
  • mono OpenSim.exe

Now see the "Configuring OpenSim" section

I'd suggest the following settings in your linux startup script for OpenSim.exe

ulimit -s 1048576

export MONO_GC_PARAMS="nursery-size=32m,promotion-age=14,minor=split,major=marksweep,no-lazy-sweep,alloc-ratio=50"

export MONO_GC_DEBUG=""

export MONO_ENV_OPTIONS="--desktop"

Configuring OpenSim

When OpenSim starts for the first time, you will be prompted with a series of questions that look something like:

    [09-17 03:54:40] DEFAULT REGION CONFIG: Simulator Name [OpenSim Test]:

For all the options except simulator name, you can safely hit enter to accept the default if you want to connect using a client on the same machine or over your local network.

You will then be asked "Do you wish to join an existing estate?". If you're starting OpenSim for the first time then answer no (which is the default) and provide an estate name.

Shortly afterwards, you will then be asked to enter an estate owner first name, last name, password and e-mail (which can be left blank). Do not forget these details, since initially only this account will be able to manage your region in-world. You can also use these details to perform your first login.

Once you are presented with a prompt that looks like:

    Region (My region name) #

You have successfully started OpenSim.

If you want to create another user account to login rather than the estate account, then type "create user" on the OpenSim console and follow the prompts.

Helpful resources:

Connecting to your OpenSim

By default your sim will be available for login on port 9000. You can login by adding -loginuri http://127.0.0.1:9000 to the command that starts Second Life (e.g. in the Target: box of the client icon properties on Windows). You can also login using the network IP address of the machine running OpenSim (e.g. http://192.168.1.2:9000)

To login, use the avatar details that you gave for your estate ownership or the one you set up using the "create user" command.
