I have a simple tree in my scene. I'm going to have it fall over and when I do, I (of course) want the branches to shake around in a realistic way, and impact on the ground. is there a way to simulate this?

In some cases you can cheat physics by

  • creating a dummy of tree simplified into some lowlopy version
    (like here by Convex Hull operator)

enter image description here

  • run Cloth sim on this dummy
  • and for highres Tree use Mesh Deform modifier to transfer simulation

Result in here looks pour, but if you will care more about topology result could be better.

enter image description here

... or probably better create a low-poly tree as extruded faces (roughly in direction of main branches), use a Cloth and for high-poly tree use Surface Deform modifier.
