Hair Dynamics do not work on a object that has been parented I currently have a sphere parented to a key chain. This sphere has hair particles. Basically, I'm trying to make a pom pom -esq key chain, similar to what Fendi makes. However, when I apply the hair particle effect and turn on hair dynamics, the hair doesn't move in the animation. I have key framed the gold chain [see image] to move, and the ball moves with the gold chain but the hair does not. Any recommendations?



Here is the blender file
It wasn't parenting. You need to start the animation on frame 1, rather than frame 38. This allows it to cache from the beginning. I figured it out by rebuilding a .blend file and testing everytime I changed something until I found the issue, which I did.

Here is the fixed (Start 38 --> 1) .blend file.
