Consider migrating to Unreal Engine

[ElmarJ]

This issue is there to track information / resources about a possible mirgation to Unreal Engine. Advantages:

• more resources available for free / within the library itself, usable with open source license. In particular: water shaders and all the megascans materials.
• they seem to be working on native Geo-Coordinate support (see https://www.unrealengine.com/en-US/blog/webinar-working-with-geospatial-gis-data-in-unreal-engine and https://github.com/ue4plugins/UEGeoCoordinates/tree/master/SimulationPlugin/Source

Or, alternatively, consider switching (at some point) to https://o3de.org/ as it has the potential to become a much more open-source-friendly alternative. Or https://godotengine.org/

The new procedural framework (currently experimental) in UE5.2 is making this more attractive... https://portal.productboard.com/epicgames/1-unreal-engine-public-roadmap/c/1016-procedural-content-generation-framework-experimental
