Hello!
You don’t need to build Unreal Engine from source for your project. The default installer version should suffice for streaming aircraft data from a Redis server and visualizing it in Unreal Engine. Since you’re not using Unreal Engine’s built-in multiplayer server models and have a separate server for data handling, the default version will provide the necessary classes and functionalities. Building from source is only needed for advanced customizations or modifying the engine itself.
Best Regards,
