-The wind anchor is used only in conjunction with the "​Palm"​ preset. The wind anchor is a point in space that moves around based on strength, direction, shape of the tree, and the values of the properties in this group. Branches and fronds that use the wind anchor will bend toward this point when the wind blows. The wind anchor is indicated by a cyan dot near the tree. +The wind anchor is used only in conjunction with the "​Palm"​ preset.
