These will be creatd according to their `.xodr` definition. The rest of landmarks present in the road map will not be physically on scene, but they can be queried using the API. +* __Pedestrian navigation.__ The ingestion will generate a `.bin` file describing the pedestrian navigation.

Warning + Make sure that the .xodr and the .fbx files have the same name. + +--- +## Map ingestion in a CARLA package + +This is the recommended method to import a map into a CARLA package. It will run a Docker image of Unreal Engine to import the files, and export them as a standalone package. The Docker image takes 4h and 400GB to be built. However, this is only needed the first time. + +__1. Build a Docker image of Unreal Engine.__ Follow [these instructions](https://github.com/carla-simulator/carla/tree/master/Util/Docker) to build the image. + +__2. Change permissions on the input folder.__ If no `.json` file is provided, the Docker will try to create it on the input folder. To be successful, said folder must have all permissions enabled for others. + +```sh +#Go to the parent folder, where the input folder is contained +chmod 777 input_folder +``` + +!!! Note + This is not necessary if the package is [prepared manually](#prepare-the-package-manually), and contains a `.json` file. + +__2. Run the script to cook the map.__ In the folder `~/carla/Util/Docker` there is a script that connects with the Docker image previously created, and makes the ingestion automatically. It only needs the path for the input and output files, and the name of the package to be ingested. If no `.json` is provided, the name must be `map_package`. + +```sh +python docker_tools.py --input ~/path_to_input_folder --output ~/path_to_output_folder --packages map_package +``` +!!! Warning + If the argument `--package ` is not provided, the Docker will make a package of CARLA. + +__3. Locate the package__. The Docker should have generated the package `map_package.tar.gz` in the output path. This is the standalone package for the assets. + +__4. Import the package into CARLA.__ + +* __On Windows__ extract the package in the `WindowsNoEditor` folder. + +* __On Linux__ move the package to the `Import` folder, and run the script to import it. + +```sh +cd Util +./ImportAssets.sh +``` + +__5. Change the name of the package folder__. Two packages cannot have the same name in CARLA. Go to `Content` and find the package. Change the name if necessary, to use one that identifies it. + +--- +## Map ingestion in a build from source + +This is method is meant to be used if working with the source version of CARLA. Place the maps to be imported in the `Import` folder. The script will make the ingestion, but the pedestrian navigation will have to be generated after that. Make sure that the name of the `.xodr` and `.fbx` files are the same for each of the maps being imported. Otherwise, the script will not recognize them as a map. + +There are two parameters to be set. + +* __Name of the package.__ By default, the script ingest the map or maps in a package named `map_package`. This could lead to error the second time an ingestion is made, as two packages cannot have the same name. __It is highly recommended to change the name of the package__. +```sh +ARGS="--package package_name" +``` + +* __Usage of CARLA materials.__ By default, the maps imported will use CARLA materials, but this can be changed using a flag. +```sh +ARGS="--no-carla-materials" +``` + +Check that there is an `.fbx` and a `.xodr` for each map in the `Import` folder, and make the ingestion. + +```sh +make import ARGS="--package package_name --no-carla-materials" +``` + +After the ingestion, only the pedestrian navigation is yet to be generated. However there are some optional steps that can be done before that. + +* __Create new spawning points.__ These will be used in scripts such as `spawn_npc.py`. Place the spawning point 2 to 3 meters above the ground, and a Route Planner's trigger box below it. Orient both in the same direction. When the vehicle falls into the trigger box, the autopilot will be enabled, and the vehicle will be registered to a Traffic Manager. + + ![ue_vehicle_spawnpoint](img/ue_vehicle_spawnpoint.png) + +* __Add the map to the Unreal packaging system.__ This will include the map along with the rest if a CARLA package is created. +`Edit > Project Settings > Project > Packaging > Show Advanced > List of maps to include...`
+ + ![ue_maps_to_include](img/ue_maps_to_include.png) + +### Generate pedestrian navigation + +The pedestrian navigation is managed using a `.bin`. However, before generating it, there are two things to be done. + +* __Add crosswalk meshes.__ Crosswalks defined inside the `.xodr` remain in the logic of the map, but are not visible. For each of them, create a plane mesh that extends a bit over both sidewalks connected. __Place it overlapping the ground, and disable its physics and rendering__. + +!!! Note + To generate new crosswalks, change the name of the mesh to `Road_Crosswalk`. Avoid doing so if the crosswalk is in the `.xodr`. Otherwise, it will be duplicated. + +![ue_crosswalks](img/ue_crosswalks.png) + +* __Customize the map.__ In is common to modify the map after the ingestion. Props such as trees, streetlights or grass zones are added, probably interfering with the pedestrian navigation. Make sure to have the desired result before generating the pedestrian navigation. Otherwise, it will have to be generated again. + +Now that the version of the map is final, it is time to generate the pedestrian navigation file. + +__1.__ Select the __Skybox object__ and add a tag `NoExport` to it. Otherwise, the map will not be exported, as the size would be too big. + +![ue_skybox_no_export](img/ue_noexport.png) + +__2.__ Check the name of the meshes. By default, pedestrians will be able to walk over sidewalks, crosswalks, and grass (with minor influence over the rest). + + + If no `.json` is provided, the name must be `map_package` + +If you don't have a .json then you don't need to specify a name unless you want to change the default map_package name. That is what I was intending to say, sorry. +* Sidewalk = `Road_Sidewalk`. +* Grass = `Road_Grass`. + +![ue_meshes](img/ue_meshes.png) + +__3.__ Name these planes following the common format `Road_Crosswalk_mapname`. + +__4.__ Press `G` to deselect everything, and export the map. `File > Export CARLA...`. A `map_file.obj` file will be created in `Unreal/CarlaUE4/Saved`. + +__5.__ Move the `map_file.obj` and the `map_file.xodr` to `Util/DockerUtils/dist`. There are several scripts there that are going to be used. + +__6.__ Run the following script to extract the crosswalks from the OpenDRIVE. This will create a `crosswalks.obj`. + +``` sh +python get_xodr_crosswalks.py -f map_file.xodr +``` +__7.__ Combine `map_file.obj` and `crosswalks.obj` running the following script. After that, the `map_file.obj` should contain both. +```sh +python addOBJ.py map_file.obj crosswalks.obj +``` +__8.__ Create the file describing the pedestrian navigation. A `.bin` will be generated in `Util/DockerUtils/Dist`. +```sh +./RecastBuilder.sh map_file.obj +``` +__9.__ Move the `.bin` into the `Nav` folder of the package that contains the map. + +--- +## Deprecated ways to import a map + +There are other ways to import a map used in previous CARLA releases. These required to manually cook the map and prepare everything, so they are now deprecated. However, they are explained below in case they are needed. + +### Prepare the package manually + +A package needs to follow a certain folder structure and contain a `.json` file describing it. This steps can be saved under certains circumstances, but doing it manually will always work. + +

+ Read how to prepare the folder structure and .json file + + +#### Create the folder structure + +__1. Create a folder inside `carla/Import`.__ The name of the folder is not relevant. + +__2. Create different subfolders__ for each map to import. + +__3. Move the files of each map to the corresponding subfolder.__ A subfolder will contain a specific set of elements. + +* The mesh of the map in a `.fbx`. +* The OpenDRIVE definition in a `.xodr`. +* Optionally, the textures required by the asset. + + +For instance, an `Import` folder with one package containing two maps should have a structure similar to the one below. + +```sh +Import +│ +└── Package01 + ├── Package01.json + ├── Map01 + │ ├── Asphalt1_Diff.png + │ ├── Asphalt1_Norm.png + │ ├── Asphalt1_Spec.png + │ ├── Grass1_Diff.png + │ ├── Grass1_Norm.png + │ ├── Grass1_Spec.png + │ ├── LaneMarking1_Diff.png + │ ├── LaneMarking1_Norm.png + │ ├── LaneMarking1_Spec.png + │ ├── Map01.fbx + │ └── Map01.xodr + └── Map02 + └── Map02.fbx +``` + +#### Create the JSON description + +Create a `.json` file in the root folder of the package. Name the file after the package. Note that this will be the distribution name. The content of the file will describe a JSON array of __maps__ and __props__ with basic information for each of them. + +__Maps__ need the following parameters. + +* __name__ of the map. This must be the same as the `.fbx` and `.xodr` files. +* __source__ path to the `.fbx`. +* __use_carla_materials__. If __True__, the map will use CARLA materials. Otherwise, it will use RoadRunner materials. +* __xodr__ Path to the `.xodr`. + +__Props__ are not part of this tutorial. The field will be left empty. There is another tutorial on how to [add new props](tuto_A_add_props.md). + +In the end, the `.json` should look similar to the one below. + +```json +{ + "maps": [ + { + "name": "Map01", + "source": "./Map01/Map01.fbx", + "use_carla_materials": true, + "xodr": "./Map01/Map01.xodr" + }, + { + "name": "Map02", + "source": "./Map02/Map02.fbx", + "use_carla_materials": false, + "xodr": "./Map02/Map02.xodr" + } + ], + "props": [ + ] +} +``` +

Take a close look at all connections and geometries. - -![CheckGeometry](img/check_geometry.jpg) - -Once the map is ready, click on the `OpenDRIVE Preview Tool` button to visualize the OpenDRIVE road network. Give one last check to everything. Once the map is exported, it cannot be modified. - -![checkopen](img/check_open.jpg) - -!!! note - _OpenDrive Preview Tool_ makes it easier to test the integrity of the map. If there is any error with junctions, click on `Maneuver Tool`, and `Rebuild Maneuver Roads`. - -### Export the map - -__1. Export the scene using the CARLA option.__ `File/Export/CARLA(.fbx+.xml+.xodr)` - -__2. Leave `Export individual Tiles` unchecked.__ This will generate only one _.fbx_ with all the pieces. It makes easier to keep track of the map. - -__3. Click `Export`.__ - -This will generate a `mapname.fbx` and `mapname.xodr` files within others. There is more detailed information about how to export to CARLA in [VectorZero's documentation][exportlink]. - -[exportlink]: https://tracetransit.atlassian.net/wiki/spaces/VS/pages/752779356/Exporting+to+CARLA - -!!! Warning - Make sure that the .xodr and the .fbx files have the same name. - ---- -## Import a map into CARLA - -This process will cook the map automatically from start to finish. Using only the .fbx and .xodr, the output will provide a fully usable CARLA map with traffic behaviour, and pedestrian navigation already implemented. - -__1. Build a Docker image of Unreal Engine.__ Follow [these instructions](https://github.com/carla-simulator/carla/tree/master/Util/Docker). The process takes quite a lot of time and disk space. Around 4h and 400GB to build the Docker image. However, this is only needed the first time. Then, the process of importing a new map is out-of-the-box. - -__2. Run the script to cook the map.__ In the folder `~/carla/Util/Docker` there is a script that connects with the Docker image previously created, and cooks the map automatically. It only needs the path for the input and output files. -```sh -python docker_tools.py --input ~/path_to_input_assets --output ~/path_for_output_assets -``` - -__3. Move the output files__ to `Content/Carla/Maps` in case they are not already there. - ---- -## Final tips - -* __Add and test traffic light timing.__ This are not set automatically, and will need trial and error to fit perfectly with the city. - -![ue_tlsigns_example](img/ue_tlsigns_example.png) - -> _Example: Traffic Signs, Traffic lights and Turn based stop._ - - -* __Place vehicle spawn points__ 2 to 3 meters above a Route Planner's trigger box, and oriented in the same direction. When the vehicle falls into the trigger box, the autopilot takes control of it. - - ![ue_vehicle_spawnpoint](img/ue_vehicle_spawnpoint.png) - -* __Show individual route planners.__ `Generate Routes` in Open Drive Actor generates the road network but it does not show these. In order to do so, do the following. - - 1. Select all `RoutePlanner` actors. - 2. Move them. - 3. Press `ctr + z`. They will show up on the map. - ![ue_route_points](img/ue_route_points.png) - -* __Modify OpenDRIVE routes.__ This can be done manually. - - ![ue_routeplanner_mod](img/ue_routeplanner_mod.png) - -* __Add the map to the Unreal packaging system.__ Go to the following path and add the level. -`Edit > Project Settings > Project > Packaging > Show Advanced > List of maps to include...`
- - ![ue_maps_to_include](img/ue_maps_to_include.png) - -* __Use CARLA materials__ contained in `Content/Carla/Static/GenericMaterials`. - * Go to the material. `Right-click on the Asset > Browse to Asset`. - * Set the actors. `Right-click on Material > Asset Actions > Select Actors Using This Asset` - - ---- -## Previous ways to import a map - -There are other ways to import a map used in previous CARLA releases. These required to manually cook the map and prepare everything, so they became deprecated when the Docker method was developed. However, they are explained below in case they are needed. - -* __A) RoadRunner plugin import.__ This software provides specific plugins for CARLA. Get those and follow some simple steps to get the map. -* __B) Manual import.__ This process requires to go through all the process manually. From importing _.fbx_ and _.xodr_ to setting the static meshes. - -

- Deprecated tutorials to import a map -

- -!!! Warning - These importing tutorials are deprecated. The best way to import a map into CARLA is to use the Docker as explained above. - -## A- RoadRunner plugin import - -### Plugin installation - -These plugins will set everything ready to be used in CARLA. It makes the import process more simple. - -__1. Locate the plugins__ in RoadRunner's installation folder -`/usr/bin/VectorZero/Tools/Unreal/Plugins`. - -__2. Copy those folders__ to the CarlaUE4 plugins directory `/carla/Unreal/CarlaUE4/Plugins/`. - -__3. Rebuild the plugin__ following the instructions below. - -* __a) Rebuild on Windows.__ - * Right-click the `.uproject` file and `Generate Visual Studio project files`. - * Open the project and build the plugins. - -* __b) Rebuild on Linux.__ - * Run the following command. -```sh -> UE4_ROOT/GenerateProjectFiles.sh -project="carla/Unreal/CarlaUE4/CarlaUE4.uproject" -game -engine -``` - -__4. Restart Unreal Engine.__ Make sure the checkbox is on for both plugins `Edit > Plugins`. - -![rr_ue_plugins](img/rr-ue4_plugins.png) - -### Import map - -__1. Import the _mapname.fbx_ file__ to a new folder under `/Content/Carla/Maps` with the `Import` button. - -![ue_import](img/ue_import_mapname.png) - -__2. Set `Scene > Hierarchy Type`__ to _Create One Blueprint Asset_ (selected by default). -__3. Set `Static Meshes > Normal Import Method`__ to _Import Normals_. - -![ue_import_options](img/ue_import_options.png) - -__4. Click `Import`.__ -__5. Save the current level__ `File > Save Current As...` > _mapname_. - -The new map should now appear next to the others in the Unreal Engine _Content Browser_. - -![ue_level_content](img/ue_level_content.png) - ---- -## B- Manual import from files - -This is the generic way to import maps into Unreal Engine using any _.fbx_ and _.xodr_ files. As there is no plugin to ease the process, there are many settings to be done before the map is available in CARLA. - -__1. Create a new level__ with the **Map** name in Unreal `Add New > Level` under `Content/Carla/Maps`. -__2. Copy the illumination folder and its content__ from the BaseMap `Content/Carla/Maps/BaseMap`, and paste it in the new level. Otherwise, the map will be in the dark. - -![ue_illumination](img/ue_illumination.png) - -### Import binaries - -__1.

Check the following options.__ - -* Convert Scene Unit -* _To import materials and textures._ - * Material Import Method - _To create new materials_ - * Import Textures - -![ue_import_file](img/ue_import_file.png) - -__3. Check that the static meshes have appeared__ in the chosen folder. - -__4. Drag the meshes__ into the level. - -![ue_meshes](img/ue_drag_meshes.png) - -__5. Center the meshes at point (0,0,0)__ when Unreal finishes loading. - -![Transform_Map](img/transform.jpg) - -__6. Generate collisions__. Otherwise, pedestrians and vehicles will fall into the abyss. - -* Select the meshes meant to have colliders. -* Right-click `Asset Actions > Bulk Edit via Property Matrix...`. - - ![ue_selectmesh_collision](img/ue_selectmesh_collision.png) - -* Search for _collision_ in Property's Matrix search box. -* Change `Collision complexity` from `Project Default` to `Use Complex Collision As Simple`. - - ![ue_collision_complexity](img/ue_collision_complexity.png) - -* Go to `File > Save All`. - -__7. Move the static meshes__ from `Content/Carla/Maps/mapfolder` to the corresponding `Carla/Static` subsequent folder. This will be meaningful for the semantic segmentation ground truth. - - * `Terrain/mapname` - * `Road/mapname` - * `RoadLines/mapname` - -```sh -Content -└── Carla - ├── Blueprints - ├── Config - ├── Exported Maps - ├── HDMaps - ├── Maps - └── Static - ├── Terrain - │ └── mapname - │ └── Static Meshes - │ - ├── Road - │ └── mapname - │ └── Static Meshes - │ - ├── RoadLines - | └── mapname - | └── Static Meshes - └── Sidewalks - └── mapname - └── Static Meshes -``` - -![ue__semantic_segmentation](img/ue_ssgt.png) - -### Import OpenDRIVE files - -__1. Copy the `.xodr` file__ inside the `Content/Carla/Maps/OpenDrive` folder. -__2. Open the Unreal level.__ Drag the _Open Drive Actor_ inside the level. It will read the level's name. Search the Opendrive file with the same name and load it. - -![ue_opendrive_actor](img/ue_opendrive_actor.png) - ---- -## Set traffic behavior - -Once everything is loaded into the level, it is time to create traffic behavior. - -__1. Click on the _Open Drive Actor_.__ -__2. Check the following boxes in the same order.__ - -* Add Spawners. -* _(Optional for more spawn points)_ On Intersections. -* Generate Routes. - -This will generate a series of _RoutePlanner_ and _VehicleSpawnPoint_ actors. These are used for vehicle spawning and navigation. - -### Traffic lights and signs - -Traffic lights and signs must be placed all over the map. - -__1. Drag traffic light/sign actors__ into the level and place them. -__2. Adjust the [`trigger volume`][triggerlink]__ for each of them. This will determine their area of influence. - [triggerlink]: python_api.md#carla.TrafficSign.trigger_volume - -![ue_trafficlight](img/ue_trafficlight.png) - -__3. In junctions, drag a traffic light group actor__ into the level. Assign to it all the traffic lights involved and configure their timing.

For simplifying this newly created folder structure, we recommend having -as many subfolders as maps to import and one single subfolder containing all the props to import. -Inside each subfolder, we will place all the files needed for importing.
-So basically, for a **map** subfolder, we will need to place the following files: - -* The map itself in `.FBX` format. -* Optionally, the textures required by the map. -* Optionally, the `.xodr` OpenDrive file corresponding to that map. - -And for the **props** folder, we will need the following files: - -* The prop itself in `.FBX` format. -* Optionally, the textures required by the prop. - -Additionally, we have to create a **JSON file inside the package** that will contain information -about its assets. The file extension must be `.json`.
