I've made a couple trees/bushes with the Sapling add-on and then distributed them over a landscape with a hair particle system. The original trees have a "swaying in the wind" animation and when they get duplicated through the particle system, although the size and rotation of the trees is randomized, their animation remains fairly homogenous: they all sway in the same directions at the same rate.
Is there a way to randomize this through the particle system, or do I need to make multiple source trees with different animations attached to them?
I still want them to look like they are being affected by the same environment/wind but as it is now it's too synchronized. I've already given the different tree types and bushes different wind speeds and amounts of "gust variation" through the sapling generator options, but this doesn't seem to be effective enough.
