C4D Hair Module | Animating and conforming hair to the shape of a collider
I’m building this animation for a project at work, and I’m having a heck of a time trying to get the hair to interact properly with the hair collider objects.
As you can see in the animation I’ve linked below, I’m trying to get the hair to interact with the curling iron.
This is my first time using the hair module for anything, and while I don’t consider myself to be a newbie with C4D, I’m by no means an expert and would love some advice or help in any way. Tell me what I’m doing wrong or if there’s an alternate way to animate this. Also, I’m trying to get the hair to conform to the jaw shape of the iron as it releases as to effectively show that the iron is crimping the hair.
Thanks,
Ben

if you have any of the hair material options (Kink, Frizz etc) on that move the hair around it won’t collide the way you expect

That’s VERY good to know!

Also, if you have rest mix/hold turned on in hair dynamics it seems to mess things up.
You may want to crank up Dynamics>Advanced>Steps, too. That determines how many times collisions are evaluated per from.

Unfortunately, Brian, the hair is still going through the collider. I wanted to put a hair collider on the entire curling iron, but for some reason, it won’t activate if the hair collider tag is placed on a null object (which has all the elements of the curling iron in it), so I had to put hair collider tags on the jaws of the curling iron. That seemed to work, but the hair goes through the geometry of the jaws.
Is there a setting in the hair collider tag that I’m missing that tells the hair to look at the whole geometry when calculating the dynamics of the collision?

Adam,
Thank you for your response! I have the rest hold set to 50% for the clump of hair that the curling iron interacts with because I want stay in that shape as if some invisible hand is holding the hair straight out.
I tried doing this (and I’ll try again), but I didn’t do a full render. Instead, after changing some of these per step values, I cached the dynamics and they didn’t seem to solve anything. I’ll try a solution where I deactivate the rest hold and up the per steps and iterations. By the way, do you know the difference between “per steps” and “iterations”? Are there settings that you might recommend??
Let me know,

Yep, I can see how you’d have a problem without rest hold. Maybe you could animate it so it cuts off when the iron clamps down, but that might look odd. Otherwise, maybe a higher stiffness value?
Re iterations, I checked in the help docs and (to my surprise) it influences the tension of the dynamic springs. It says that the number should generally be equal to the number of segments.
