I’ve had this problem also, where the wind for a particular object e.g.a blowing flag disrupts other objects in the scene. it can be very annoying, especially if you are trying to combine various elements in a scene. You suggest putting a field around the flag…could you do it the other way? where you maybe just put a field (box field) around the e.g.table cloth so it is protected and not affected by the wind for the flag?
