Yo brisck1!
I did not look really in depth into this tutorial series but I bought the project from Sander Vander Meiren on gumroad, which looks extremely similar, and studied it in depth.
It looks nice and all but it’s very jiggly and from the few tests I ran, only works for smaller foliage. I just couldn’t have a simulation with a larger physical volume that is both reacting very gently and without interferance with the player.
