The process runs until it encounters a junction, so it can actually span multiple roads.įor this to work, actors are assumed to use the standard Unreal Engine alignment (X+ forward, Z+ up), except Decals, for which Y- forward and X- up are expected.Don't expect "close focus" like 1 foot or so, I was simply trying to distinguish the 5-30 foot range from the 100+ yard range for classical landscape photography. This Editor Utility Blueprint allows any actor to be duplicated along any road at a fixed step.

No material are included with the plugin, but many can be found for free on Quixel. This Blueprint can randomly spawn a selection of Decal on the drivable lanes ideal for placing asphalt defects, tar lines, oil splats, etc. It seems to be an Unreal Engine bug, and the current workaround is to manually apply a single paint touch to each landscape grid unit, which will instantly remove all foliage on painted roads for that grid unit. Layer painting won't remove foliage from the previous layer.Those can be manually removed with standard sculpting tools Sculpting can miss parts of the landscape in junctions, leaving spikes.In the video above, the road network was generated using RoadRunner This feature doesn't include drawing the actual road network, it only sculpts the landscape to perfectly fit along the roads. You can set the falloff, the height offset and the layer to paint under roads. This Editor Utility Blueprint automatically sculpts your selected landscapes based on your OpenDRIVE roads. But you can check out Der Sky's Marketplace products, which probably has what you need.
No signs (or any prop) are included in this plugin. You can also set offsets on the sign's track coordinate. This Blueprint can spawn any actor (usually signs or traffic lights) for all roads incoming to a junction. OpenDRIVE SplineĪ basic spline with an added feature to align all spline point to their lane center. This small editor Blueprint actor automatically updates its track coordinate when moved around the scene, making road and junction identification much easier. The OpenDRIVE Vehicle component can be attached to WheeledVehicle and provides some metrics commonly used in driving simulation.
It also interfaces some basic OpenDRIVE functions to Blueprint. The OpenDRIVE component can be attached to any actor to get or set its position on OpenDRIVE's track coordinate.

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. Once you've set the plugin World Settings class as default, you can open or create a level, and set its OpenDRIVE Asset via a property in the World Settings tab. WorldSettingsClassName=/Script/OpenDRIVE.OpenDriveWorldSettings Add the OpenDRIVE file to your level This is done by adding the following to your DefaultEngine.ini. To do that, you have to use the plugin's own World Settings class. Since OpenDRIVE files are tightly linked to their related scenes, the current workflow is to set the OpenDRIVE asset used for each world/level. The import process is similar to all other types of assets, so the official documentation should be able to guide you. The plugin adds a new OpenDRIVE asset type, meaning you can (and should) import your. There are a few steps to follow before jumping into the features. The easiest workaround for this is to rotate the imported scene's root actor -90° around the Z axis in Unreal Engine. In this case, it means there ends up being a 90° rotation mismatch along the Z axis between a mesh and an OpenDRIVE file both exported from RoadRunner. For instance, Mathworks' RoadRunner instead maps OpenDRIVE's (X, Y) axes to Unreal Engine's (Y, X). This assumption can differ from the one made by various other tools provider. To convert between those, the plugin assumes X and Z are common, and Y is flipped. OpenDRIVE uses a right-handed coordinate system, whereas Unreal Engine uses a left-handed coordinate system. The simplest workaround is to delete this plugin's ATrafficLightController class to remove the conflict. For UE >= 5.0, you'll want to use the chaos branch, as master currently uses PhysX.įor CARLA users: due to conflicting classes name, the plugin doesn't work as-is alongside CARLA.
The plugin has been tested with Unreal Engine versions from 4.26 to 5.0. For Linux support, it is being discussed in #8.

Currently, this plugin supports Windows only.
