I’m using a hair object with the “Generate” tab set to “instance” and the object set to a hair card I’ve modeled. The guides are applied to a rigged model’s head and the instances have all been applied individually. Even with dynamics turned off, the hair doesn’t stick to the model when it’s animated. I’ve tried caching, changing the “priority” in the “basic” tab of the hair object, making the hair object a child of the head bone, changing the instance type to just “spline”. None of these make any difference. Anyone have any ideas? My project is too large to attach to the post (8mb).

Hi folschild,

Please have a look here:

Load version 01 and check as well (via merge in a new project) the abc version. Is that what you get?

Then check out version 02, especially the abc version, to see what I saw.

What I did was to place a correction Deformer under the Hair to get access to the vertices. Then I used the point cache to cache those and dialed the offset of the Point Cache to -1.

Is that working for you?

All the best

I’m not totally sure I’m seeing what you’re trying to show me, but I do see the hairs lagging behind the animation in v2. I may have worked out a solution with maxon support where the hair instances have to be added to a “scalp” without any binding to the rig, and then making that a child of the head bone. Then changing the hair object priority to -499 and set to “generate.” The existing instances detach from their original positions and have to be redone, but going forward this seems like it could work.

That being said, I don’t understand how this isn’t a problem for every person using hair with a rigged model in C4D. I would think the hair object was created specifically for this purpose, so having to use a work around at all is rather disappointing.

Thanks for the reply, folschild.

I’m glad you were able to work with the support on that.

I see it rarely that people use Generate> Instances.

I see this while I have placed the camera below the Joint.1 to be taken along the ride with a stable view.

Enjoy your weekend

I can understand people using instances rarely, but it was giving me the same result when I set the guides to splines. Is this considered a bug?

Hi folschild,

It feels like the Generator Hair has an Instance generator priority issue, IMHO.

I leave it to the tech support and developer to classify it.

Sorry that I can do more.

All the best

Thank you very much for taking a look.

You’re very welcome, folschild.

Even I think I was not a great help. At least file 01 confirms your findings.

Have a great weekend
