Export Digital Twins generated map plugins for use in packaged CARLA project

[Aperiss]

Context:

• We have a map-generation tool that produces .umap files and associated assets for real-world environments.
• In the Unreal Editor, these generated maps work flawlessly when loaded directly in CARLA’s project in Editor Mode.
• Attempts to cook/package these maps as a plugin from our external project and then import them into a prebuilt CARLA package have failed:
  • Unreal Engine binds cooked assets to the exact project configuration, engine version, and platform used during packaging.
  • A packaged CARLA build lacks the source .uproject, plugin manifests, and build metadata necessary for cooking new plugins or DLC
  • CARLA’s runtime does not automatically detect or mount new content paks or plugins in a shipped binary.
• Unreal requires the original project archive and source to produce compatible DLC.
  Currently it has not been possible to inject new maps into a packaged CARLA build without rebuilding the package.

Task:
Investigate a way to make the generated plugins work within the precompiled CARLA package. Look into how UE5 projects are packaged, and if engine errors while loading data within the plugins can be worked around
