When I use Simulate to simulate hair, the model animation is always moving and fast, but I cannot control the stretching of the hair following the animation movement in the simulator. The hair always appears soft, I do n’t I know how to control the hardness value of my hair. The hair will be pulled straight when following the motion of the animation. I have tried to make the constraint Iterations higher, but the result is that it will not be pulled very long. Will be straightened, I don't know how to solve this problem, I am a newbie, hope someone can help me! With my simulation parameters, I hope to put forward your valuable suggestions and point out that I have something wrong, I will be very grateful!
