From looking around so far, the best way seems to be to use a spline ik system where the wind would affect a curve which would drive the joint of a branch. That seems to work fine for one branch. But how do I deal with the secondary and tertiary branches that stem off the main one? Can you nest this kind of spline ik system within another such system, potentially several times?
Anyway I just wanted to see if there was an easier way to go about this before I dive into it. Thanks!
