Hair gets warped when colliding with collider object
on Mar 4, 2018 at 10:25:09 am

Hi,

I work on a project in which I must show the use of a toothbrush.
For the brush, I used the Hair tool, and so far all went well until I use the Dynamics collision option.
For some reason, the tip of the hair turns sticky to the collider object, and I don't know why.
I am really stuck with this problem with no solution.
Can any of you show me how to overcome this problem?
I will attach a picture of the explanation once I know how to upload with this message.

Kind Regards
Andy

Hi,
I think the problem is that you spawn the hair right in the object so it got stuck in there. Place the toothbrush next to the teeth and animate it to the position you want. Or you reduce the length of the hair.

Hi Maxim Fischer,

Thank you very much for your reply.
Yes, I start the animation outside the frame, and when the brush touches the tooth, only then started the problem.
But I solved the problem on my own.
Played a little bit around with the parameters of "Rest mix" and "Rest Hold" and I also increased the iterations and the steps in the "Advanced" panel.
That solved it all, and I'm rendering right now without having any more issues.

Thanks for helping
It is always great to find someone here to help you solve the problem.
Hope to return one day the favour.

Kind Regards
Andy
