The spine-ue4 runtime for Unreal Engine does support importing Spine data such as .json and .atlas files into your game. However, for importing these files at runtime after the game is packaged, you would need to implement custom functionality. The spine-ue4 runtime primarily facilitates importing and managing Spine assets within the Unreal Engine Editor, and there is no built-in feature for importing Spine data at runtime in a packaged game. You might need to explore custom scripting or use the spine-cpp runtime to handle such functionality.
