Extract JSBSim's wind system as an actor for UE5.1

[junaidbinsarfraz]

I have an Ultra Dynamic Sky plugin for UE5.1 weather system (Blueprints). It has an all-weather system and wind to interact with the weather system. I can assign a custom wind actor for the wind system.

In JSBSim, also has its own wind system which interacts with the flight (like DRAG, SIDE, and LIFT). If I use both wind systems then the result will be very ambiguous. The best possible way is to attach JSBSim's wind actor with the plugin's wind actor so that there will be no contradictions in the scene and physics. I am not sure how to attach JSBSim's wind to the plugin's wind actor. I am even not sure if it is a good idea or not.

Looking forward to ideas and demo implementations for this problem.

If the Ultra Dynamic Sky plugin has some API where you get to specify the wind and/or an API for you to retrieve the current wind conditions then simply update the wind in JSBSim on each time step.
