|

There is no "CarlaUE4.sh" script in the source version of CARLA, you need to
|
||||
follow the instructions in the [documentation](http://carla.readthedocs.io) on
|
||||
building CARLA from source.

|

Once you open the project in the Unreal Editor, you can hit Play to test CARLA.

To compile a binary (packaged) version of CARLA, open the CarlaUE4 project with

Unreal Editor, go to the menu "File -> Package Project", and select your

platform. This takes a while, but in the end it should generate a packaged
