Pivot Painter 2 Wind direction and Interaction

Was wondering if anyone had any resources or could point in me the direction of how to go about setting up and using wind for Pivot Painter 2? My material instances dont seem to have anything like a “wind direction” built in, so curious as to how you would go about achieving this. Beyond simple wind direction/intensity controls, it would be great to know how to even begin looking into player character interaction. Would love some tips if anyone knows anything!
