Create distribution packages for assets
It is a common practice in CARLA to manage assets with standalone packages. Keeping them aside allows to reduce the size of the build. These asset packages can be easily imported into a CARLA package anytime. They also become really useful to easily distribute assets in an organized way.
- Export a package from the UE4 Editor
- Export a package using Docker
- Import assets into a CARLA package
Export a package in a CARLA build from source
Once assets are imported into Unreal, users can generate a standalone package for them. This will be used to distribute the content to CARLA packages such as 0.9.8.
To export packages, simply run the command below.
make package ARGS="--packages=Package1,Package2"
This will create a standalone package compressed in a
.tar.gz file for each of the packages listed. The files will be saved in
Dist folder on Linux, and
/Build/UE4Carla/ on Windows.
Export a package using Docker
Unreal Engine and CARLA can be built in a Docker image which can then be used to create a package or export assets for use in a package.
To create the Docker image, follow the tutorial here.
When you have the image ready:
- Navigate to
- Create a CARLA package or prepare assets for use in a package by running one of the following commands:
# To create a standalone package ./docker_tools.py --output /output/path #To cook assets to be consumed in a CARLA package ./docker_tools.py --input /assets/to/import/path --output /output/path --packages PkgeName1,PkgeName2
Import assets into a CARLA package
A standalone package is contained in a
.tar.gz file. The way this is extracted depends on the platform.
- On Windows extract the compressed file in the main root CARLA folder.
- On Linux move the compressed file to the
Importfolder and run the following script.
cd Import ./ImportAssets.sh
That sumps up how to create and use standalone packages in CARLA. If there is any unexpected issue, feel free to post in the forum.
