Windy Grass

I’m just playing around at the moment with a wind and foliage in Unreal. The wind in Unreal is pretty simple, but I want to come up with a way of doing trunks, then branches which inherit movement from the trunks, and then leaves and so on. Each with their own layer of wind on top.

So far I have only modelled some very simple foliage and applied a little simplegrasswind to it, which is being driven by scalar values held in a material parameter collection. I wonder if there is a way to control the direction of the wind…
