I already have a plugin built for UE 5.3 that exposes the recalc wave so you can change gerstner wave properties dynamically via blueprints. Just put this in your plugins folder and now you have that function for blueprints and you can see how I use it from the blueprint in my previous post. delebash/UnrealWaterLibrary: expose recalc gerstner wave to blueprints (github.com). I have never used OSC data but this looks like a nice blueprint library you could use videofeedback/Unreal_Engine_SerialCOM_Plugin: Serial Com Port Library for Unreal Engine 4 and Unreal Engine 5 (github.com)
