> This is the development branch `ue5-dev` for the **Unreal Engine 5.3 version of CARLA**. This branch exists in parallel with the Unreal Engine 4.26 version of CARLA, in the `ue4-dev` branch. Please be sure that this version of CARLA is suitable for your needs as there are significant differences between the UE 5.3 and UE 4.26 versions of CARLA.

This will download and install Unreal Engine 5.3, install the prerequisite requirements and build and launch CARLA. It may take some time to complete and use a significant amount of disk space. For further instructions on building in Linux can be found [here][buildlinuxlink] and the instructions for building in Windows can be found [here][buildwindowslink].
The ad-rss-lib library compiled and linked by the [RSS Integration build variant](Docs/adv_rss.md) introduces [LGPL-2.1-only License](https://opensource.org/licenses/LGPL-2.1).
CARLA uses three dependencies as part of the SUMO integration:
- [PROJ](https://proj.org/), a generic coordinate transformation software which uses the [X/MIT open source license](https://proj.org/about.html#license).
- [SQLite](https://www.sqlite.org), part of the PROJ dependencies, which is [in the public domain](https://www.sqlite.org/purchase/license).
- [Xerces-C](https://xerces.apache.org/xerces-c/), a validating XML parser, which is made available under the [Apache Software License, Version 2.0](http://www.apache.org/licenses/LICENSE-2.0.html).
CARLA uses one dependency as part of the Chrono integration:
- [Eigen](https://eigen.tuxfamily.org/index.php?title=Main_Page), a C++ template library for linear algebra which uses the [MPL2 license](https://www.mozilla.org/en-US/MPL/2.0/).
CARLA uses the Autodesk FBX SDK for converting FBX to OBJ in the import process of maps. This step is optional, and the SDK is located [here](https://www.autodesk.com/developer-network/platform-technologies/fbx-sdk-2020-0)
