Getting Started in OpenSim


This blog post is to assist new users to get started quickly with the creation of a new “avatar” in OpenSimulator (also known as “OpenSim”), an open source virtual world server similar to the commercial Second Life service and accessed with the same sort of virtual world “viewer” as is used for Second Life. It also gives a quick guide to your initial login on an OpenSim “grid” and your first visit a virtual world “region” on that grid. Finally it describes how to visit other connected grids that make up the virtual world “Metaverse” via the “Hypergrid”.

1. Register for an Avatar on OSGrid

OSGrid is a grid provided by OpenSim community members and enthusiasts and often used for development testing and community meetings. It runs entirely on donations from users. It allows anyone to create a free avatar and even to attach “regions” hosted on their own servers or home computers. Create an avatar and select an avatar name at

2. Initial Grid Login and Avatar Setup

Download and install a suitable virtual world viewer on a system that has a good graphics capability. The viewer should be OpenSim capable. The standard open source Linden Lab provided viewer incorporates a commercially licenced physics engine (Havok) which means it cannot be directly used for OpenSim access, but many third party viewers based on the same core open-source code are suitable. I recommend Firestorm… under the download tab select the variant that indicates its “For SL & Opensim”. Windows (32 bit and 64 bit), Mac and Linux versions are available.

Run the viewer, select the grid to log into as “OSGrid” and log in with the avatar name and password you created earlier. When you are logged in you normally initially arrive at an introductory or welcome region where help boards can assist you in understanding how to use the avatar and camera movement keys and do other simple operations. You can also usually select some free avatar appearances there. Don’t worry if you initially appear as a “cloud”… it just means you don’t have an initial preselected appearance. Some grids set up such a default appearance (the “Ruth” default basic avatar is common), others don’t. “Wear” one outfit and if you want you can change your appearance in the viewer.

3. Visit a Virtual World Region

When you feel ready you can go to locations on the grid you are on. Look at the map (accessible by one of the viewer buttons, hover over them to get tool tips) and type in a name of a region if you know where you wish to visit from information on the web. Or you can also type the destination region name in the top address bar in the viewer. Try visiting the “Oil Rig” region perhaps.. a rich oil rig training demonstration region…


4. Hypergrid – Roam the Metaverse

OpenSim grids can be opened up to visits by avatar from different grids using a protocol for movement and data exchange called the “Hypergid”. You can visit by typing appropriate addresses in the map tool or address bar. Find the addresses via web pages describing such destinations. Try cut and paste of this “hop” address into the address bar to visit the “AiLand” grid “Castle” region…


Hypergrid-Safari-Sign-Trans-CroppedIf you want to take a short tour or safari through some of our own demonstration regions… and pick up various avatar outfits and tools as you travel. Take a look at his blog post for some locations… convenient signs on the regions can be clicked to automatically “teleport” you to the next locations…

5. Going Further

There are many facilities in OpenSim, but find your feet and make sure you can do basic movement, use the camera separate to movement of the avatar, sit down, text chat to others and even try to connect a headset for voice before you go further. Media playback on screens in OpenSim may require media plugins if suitable versions are not already on your computer. Others in world, or a search on the web can give more guidance, e.g. here.

It is possible to add your own regions and your own content to OpenSim. OSGrid makes available a ready-to-run download of the code to add a region onto the OSGrid grid. See OSGrid’s Download and Grid information pages for advice.
