I am trying to model an ornamental grass procedurally (Miscanthus sinensis 'Gracillimus'). I want to be able to do this procedurally (not combing for example) because, unlike normal grass, it has a lot of strands with a specific form and I still want to be able to adjust it fastly to make variations or similar plants.

As shown in the screenshot, I tried using hair dynamics, which approches the result I want. But despite that I just can't get it right using this method.

My knowledge of hair dynamics and physics isn't yet adequate enough. Maybe someone knows the best practices to accomplish the creation of this plant?

    $\begingroup$ Not sure reading your question about what could be good or bad in the hair model? Is that kind of thing you are looking for? i.stack.imgur.com/PqFnD.jpg $\endgroup$ – lemon Jul 28 '19 at 13:41
  • $\begingroup$ Sorry for not being clear. Yes indeed, the outer ones of your image are the thing I'm looking for. In my model the strands flare out almost inmediatally which prevents the right form. Meanwhile I'm making progress and it is going the right way. I wasn't using the Pin Goal Strength which was the main reason it did not work well. But I can still use the help. How did you do it? $\endgroup$ – Vince Jul 28 '19 at 13:58
  • $\begingroup$ I've used keyed (see in physics) particles (not hair but emitter) with path rendering. The idea is to propagate the particles from a shape to another (in the image I've upload 3 shapes per plant). So particles will start at the first then go to the 2nd and finally reach the third. As each step is "the mesh you want" you can control nearly all rapidly. $\endgroup$ – lemon Jul 28 '19 at 14:03
  • $\begingroup$ Seems like a good method. You mean like this: youtube.com/watch?v=UgmJsLcLXUI but then with path rendering? $\endgroup$ – Vince Jul 28 '19 at 14:24
  • $\begingroup$ Yes, same principal but with path. The one I did in the image is based on a disk for the first, an half sphere for the second and a half sphere opened at the top for the third. From that, just move them, rotate, scale, deform them as you want to make variations. $\endgroup$ – lemon Jul 28 '19 at 14:29
