Unreal Engine OpenDRIVE plugin
This plugin allows you to manipulate your OpenDRIVE road network in Unreal Engine. It is built around esmini's RoadManager, which does most of the heavy work. I encourage you to check out this project, which also includes OpenSCENARIO support.
Installation
RoadManager is included as a submodule to this repository, so make sure to initialize and update submodules. For example:
git clone --recurse-submodules [email protected]:brifsttar/OpenDRIVE.git
How to use
There are a few steps to follow before jumping into the features.
Import the OpenDRIVE file
The plugin adds a new OpenDRIVE asset type, meaning you can (and should) import your .xodr file into the engine. The import process is similar to all other types of assets, so the official documentation should be able to guide you.
Change your default Level Script Actor
Since OpenDRIVE files are tightly linked to their related scenes, the current workflow is to set the OpenDRIVE asset used for each world/level. To do that, you have to use the plugin's own Level Script Actor.
This is done via the Project Settings, see the screenshot below.
Add the OpenDRIVE file to your level
Once you've set the plugin Level Script Actoras default, you can create a new level, and set its OpenDRIVE Asset via a property in the Level Blueprint.
Once that is done, your OpenDRIVE file should be properly loaded, and you can start using the plugin's features, or add your own using the full power of esmini's RoadManager.
Features
OpenDRIVE Component
The OpenDRIVE component can be attached to any actor to get or set its position on OpenDRIVE's track coordinate. It also interfaces some basic OpenDRIVE functions to Blueprint.
OpenDRIVE Vehicle Component
The OpenDRIVE Vehicle component can be attached to WheeledVehicle and provides some metrics commonly used in driving simulation.
OpenDRIVE Reader
This small editor Blueprint actor automatically updates its track coordinate when moved around the scene, making road and junction identification much easier.
OpenDRIVE Spline
A basic spline with an added feature to align all spline point to their lane center. Useful to create car trajectories.
Junction Spawner
This Blueprint can spawn any actor (usually signs or traffic lights) for all roads incoming to a junction. You can also set offsets on the sign's track coordinate.
No signs (or any prop) are included in this plugin. But you can check out Der Sky's Marketplace products, which probably has what you need.
Landscape Sculpting
This Editor Utility Blueprint automatically sculpts your selected landscapes based on your OpenDRIVE roads. You can set the falloff, the height offset and the layer to paint under roads.
