.OAR File

What is an OAR file?

An OAR file, also known as an OpenSimulator Archive file, is a compressed archive file format used by the OpenSimulator application. OpenSimulator is an open-source 3D application server for creating virtual environments accessible to multi-users over the network. OAR files can be used to save and load regions, objects, and assets in OpenSimulator.

OAR files are binary files that contain a variety of data, including:

• Terrain data
• Object data
• Asset data (textures, scripts, etc.)
• Region parcel data
• Inventory data

OAR files can be used to create and share virtual worlds in OpenSimulator, or to back up and restore virtual worlds. They can also be used to convert virtual worlds to other 3D formats, such as OBJ and FBX.

Here are some examples of how OAR files can be used:

• To create a new region in OpenSimulator, you can load an OAR file containing the region data and terrain.
• To add an object to a region in OpenSimulator, you can load an OAR file containing the object data and assets.
• To back up a region in OpenSimulator, you can save the region to an OAR file.
• To restore a region in OpenSimulator, you can load the OAR file containing the region data.
• To convert a virtual world in OpenSimulator to another 3D format, such as OBJ or FBX, you can export the virtual world to an OAR file and then convert the OAR file to the desired format.

OAR files are a powerful tool for creating, managing, and sharing virtual worlds in OpenSimulator.

How to open an OAR file?

There are two main ways to open an OAR file:

1. Using OpenSimulator: If you have OpenSimulator installed on your computer, you can open an OAR file by double-clicking on it. This will load the OAR file into OpenSimulator and create a new region or object, depending on the contents of the OAR file.
2. Using a third-party OAR viewer: There are also a number of third-party OAR viewers available that can be used to open OAR files without the need for OpenSimulator. Some popular OAR viewers include:
   • OAR Viewer
   • OpenSim Archive Explorer
   • OAR Convert

How to convert an OAR file?

There are a number of ways to convert an OAR file to other formats.

One way is to use a third-party OAR converter tool. Some popular OAR converter tools include:

• OAR Converter
• OpenSim Archive Converter
• BVHacker

Another way to convert an OAR file is to use OpenSimulator itself. To do this, you can open the OAR file in OpenSimulator and then export the region or object to another format. To do this, follow these steps:

1. Open OpenSimulator and load the OAR file.
2. Select the region or object that you want to convert.
3. Click on the Export button.
4. Select the format that you want to convert to and click on the Save button.

How to create an OAR file?

To create an OAR file, you can use OpenSimulator or a third-party OAR creator tool. To create an OAR file in OpenSimulator, follow these steps:

1. Open OpenSimulator and select the region or object that you want to save to an OAR file.
2. Click on the Save button.
3. Select the OAR file format and click on the Save button.

To create an OAR file using a third-party OAR creator tool, follow the instructions provided by the tool.

How to use OpenSimulator archives?

OpenSimulator archives can be used to create and share virtual worlds, back up and restore virtual worlds, and convert virtual worlds to other 3D formats.

To create a new region in OpenSimulator, you can load an OAR file containing the region data and terrain. To add an object to a region in OpenSimulator, you can load an OAR file containing the object data and assets. To back up a region in OpenSimulator, you can save the region to an OAR file. To restore a region in OpenSimulator, you can load the OAR file containing the region data. To convert a virtual world in OpenSimulator to another 3D format, such as OBJ or FBX, you can export the virtual world to an OAR file and then convert the OAR file to the desired format.

Troubleshooting OAR files

If you are having problems with an OAR file, there are a few things you can try:

• Make sure that you are using the correct version of OpenSimulator to open the OAR file.
• Try opening the OAR file in a third-party OAR viewer.
• Try converting the OAR file to another format and then opening the converted file.
• If you are still having problems, you can try searching for help online or contacting the OpenSimulator community.

Using OAR files to create and share virtual worlds in OpenSimulator

OAR files are a powerful tool for creating and sharing virtual worlds in OpenSimulator. To create a new virtual world, you can create a new region in OpenSimulator and then export the region to an OAR file. Once you have exported the region to an OAR file, you can share the OAR file with others so that they can load the region into their own OpenSimulator servers.

To share a virtual world created using OpenSimulator, simply export the region to an OAR file and then share the OAR file with others. You can share the OAR file via email, cloud storage, or file sharing websites. Once others have the OAR file, they can load the region into their own OpenSimulator servers
