Wind Sway

Bends the connected object in the wind — plants and grass from their roots, a flag from its pole — in gusts. A shader effect: the object's position, physics and picking keep their rest pose. It adds to other shader effects (Body Wave, Jiggle, Flowing Water) on the same object instead of replacing them.

Since 1.64.

Output: effect (wire into an Object Selector, or leave it in an object's own flow)

Parameters

Parameter	Default	Range
mode	plant	plant (bends from its anchor, more towards the tip) or flag (waves along its length)
anchor	bottom	the face that stays still: bottom for a plant, left for a flag on a pole on its left
strength	0.15	how far it bends
frequency	0.6	sways per second
gust	0.5	0 = a steady breeze, 1 = strong gusts
direction	0	the wind's heading in degrees
wavelength	1	flag: metres per wave
flutter	0.3	flag: small fast ripples on top

The gusts come from the shared clock, so every player sees the same gust.

Practical example

A garden: give the bushes Wind Sway (plant, anchor bottom, strength 0.2), and the flag Wind Sway (flag, anchor left, frequency 1.2).
