WindDirectionalSource not affecting skeletal mesh

Hi, I’ve created a flag and a cloth tent in Blender and am attempting to create a little wind buffeting on both, but neither seem to be affected by the WindDirectionSource I have in level.

I’m getting proper physics from each, they immediately sag with gravity when I play the level in the viewport, but after they settle they never move again. I

I’ve tried parenting them to the skeletal meshes, and vice versa, adjusted values gradually to no effect. There doesn’t seem to be any extra documentation to trouble shoot with, can anyone provide some assistance?

Solution for anyone looking at this with the same issue:

I came across a materials lesson from Epic’s learning center (Materials - Exploring Essential Concepts) using a panner and texture coordinates and a cloud texture sample (simple grayscale) to build the buffeting movement within the material itself and painting with vertexes.
Works very well.
In the series, it’s the lesson called “Material Inputs for Animation”
