OptionalenabledWhether this material sways at all. Default true.
OptionalamplitudeTip displacement at full wind as a fraction of height — so it means the same thing on a sapling and on an old oak. Default 0.065.
Low on purpose. A plant's silhouette is what the eye tracks, and past roughly a tenth of its height the bend stops reading as wind and starts reading as rubber.
OptionalstiffnessHow the bend is distributed up the plant: 1 bows evenly from the base, 2 keeps the trunk stiff and moves the crown, 4 flicks only the tip. Default 2.
OptionalheightThe plant's overall height in world units — what amplitude is a fraction
of, and the height at which the bend reaches full. Default 2.
OptionalflutterSideways shiver across the wind, as a fraction of the downwind bend. Default 0.35.
How a given plant answers the wind. Unset fields keep their current value.
