Thank you both so much. I’m pretty new at this and just assumed I was doing something wrong. It seemed like I was just missing a check box someplace. Knowing that it’s just broken has saved me countless hours trying to figure out where I went wrong and can get back to being productive (finding workarounds for this issue). I went with the older methods because my understanding was the new hair nodes were not ready for dynamics yet. I figured that many had gotten the results I needed with the older methods so I went with that. Didn’t occur to me that the new hair was being developed at the cost of the old. No worries. With all the time I will not now spend trouble shooting my work, I will find work arounds for my particular problem. Worst case, the thing I have has short hair all over that can be done with the new GN and the small patch of longer hair that should be blowing in the wind will work as long as I don’t groom it. Thanks Kent and Omar. Yes. I learned a great deal from this course. As you say, most of the methods are still valid.
