<h1>Automatically generate a map from RoadRunner</h1>

|
|
|
|
|
The given scripts only works if the files are kept in the folders
|
|
|
|
|
detailed below.
|
|
|
|
|
|
|
|
|
|
This script is aimed to reduce the time needed to setup a map inside Carla's project.
|
|
|
|
|
Also, in combination of the [import / export scripts](export_import_dist.md) will allow
|
|
|
|
|
the user to generate a simple map without opening Unreal Engine.
|
|
|
|
|
|
|
|
|
|
!!! important
|
|
|
|
|
The script does heavy use of Unreal's capabilities, so it is needed to be installed
|
|
|
|
|
and setup, as the import fbx action is done directly over the code project, not a
|
|
|
|
|
distribution build.
|
|
|
|
|
|
|
|
|

<h4>How to import a fbx</h4>
|
|
|
|
|
The current script only work for files placed with the follow structure (RoadRunnerFiles is
|
|
|
|
|
located in the root folder):
|
|

```sh

Under <i>RoadRunnerFiles</i> folder located at the Carla Root, place each "Export"
|
|
|
|
|
folder obtained from RoadRunner and rename it with the name of the map to be imported.
|
|
|
|
|
It have to match the <b>.fbx</b>
|
2019-02-18 17:30:23 +08:00
|
|
|
and <b>.xodr</b> files.
|
|
|
|
|
|
2019-03-29 01:53:35 +08:00
|
|
|
Now, simply go into the _"Util"_ folder and run <b>generate_map.py</b>
|
2019-02-18 17:30:23 +08:00
|
|
|
|
|
|
|
|

|
The script, by default, checks the <i>/Unreal/CarlaUE4/Content/Carla/ExportedMaps</i> for matching names.
|
2019-02-18 17:30:23 +08:00
|
|
|
If a map with the same name as a to-be-imported map is found, it will notify the user and won't do anything.
|
|
|
|
|
To override this, <b>generate_map.py</b> can be invoked with the <b>--force</b> flag.
|
|
|
|
|
|
|
|
|
|
After the script finishes, all a map with the same name of the folder and files will be located under
|
|
|
|
|
<i>/Unreal/CarlaUE4/Content/Carla/Maps</i> with all the static meshes and placed, textures, waypoints and routes
|
|
|
|
|
generated.
|
|
|

|
|
|
|
|

|
|
|
|
|
There is a bug in RoadRunner that generates wrong materials automatically and they get broken inside Unreal.
|
|
|
|
|
By adding the flag <b>--usecarlamats</b> the meshes will use the materials provided by Carla's project,
|
2019-03-29 01:53:35 +08:00
|
|
|
that will also <b>react to the weather</b>.
