 This is the code to create the sway of the leaves. It's basic (just uses a sinewave multiplying by the time and axis position, but works well). Notice that the strength is multiplied by the color. Every axis uses a different small near 1.0 multiplication factor so axes don't appear in sync.

 Generating complex geometry (several thousand vertices) with this node is inefficient, even if it's
 done only once. Instead, it is designed to generate simple geometry that changes every frame.
