由于 英文 好 只能 过翻译来表述 的问题

没 可能类似 过骨骼 样控制毛发动画 控制 围内毛发的动画 比如现在 个场景 个人坐在飞驰的赛车 如果用动力学模拟的话 头发都 被吹的没 了形 想 过作假的方法让头发飘动起来  起来没那么快 毕竟特殊情况 可以 实的吹动

请问 什么 路

As my English is not good, I can only express my problem through an interpreter.

Is it possible to animate hair as though it were a skeleton, controlling the animation of the hair within the range. For example, there is a scene, a person sitting in a racing car, if the dynamics simulation, the hair will be blown out of shape, I want to fake the way the hair floating up, not so fast. After all, special circumstances do not need the actual blowing.

Do you have any idea?

Hi,

 
You can control Ornatrix hair using "External Guides". You can take some Maya curves and use them to control the hair. If you can somehow rig and animate the curves then you will have full control over the movement without using a hair simulation. To do this, use the Adopt External Guides operator.

如果是C4D的版本呢 也测试过使用这个功能 您发的视频本身物体是没 在移动的 那4条 导线也是 过模拟做的动画 所以 还是没能 解如何在 个高 运动的物体 做毛发的手动动画 如果 事先做好 个样条动画 转 Ornatrix的 导线 那么 导线无法拾取样条的动画

If it is the version of C4d, I have also tested the use of this feature, the video you sent is not moving objects, and the four guides are done through simulation animation. So I still don’t understand how to do a manual animation, of hair on a high-speed object, and if I do a spline animation beforehand, and turn it into an Ornatrix lead, then the lead doesn’t pick up the spline animation.

知道 么控制模拟了 过还是 能用骨骼类似这样的控制器手动控制毛发的动画 还是只能模拟

I know how to control the simulation, but I still can’t manually control the animation of the hair with a controller like the skeleton. Or is it just a simulation

The video was to show you how to use Adopt External Guides node, but it's up to you to rig and animate the curves manually. Ornatrix doesn't provide rigging tools, only tools for hair simulation.

白您的

想 述的 是 假如 个已经做好动画的样条了 如何让ornatrix识别动画 可以 用ornatrix来直接制作 但是 要 个功能来让ornatrix识别到样条动画 来驱动接 来的 导线动画 然 导线驱动毛发 来完 要的动画效果
样条的动画 是可以脱离ornatrix系统来制作的 这是完全没问题的
Adopt External Guides node这个在C4D里也只能把ornatrix系统整个作为参 并 能是把做好的样条动画作为参 所以在使用这个功能之前 还 要 步 就是如何让ornatrix识别 部的样条动画 这个是困扰 的问题

What I’m trying to say is, if I have a spline that’s already animated, how do I get Oratrix to recognize the animation, I don’t need Oratrix to do it directly, but I need a function to get oratrix to recognize the spline animation, to drive the next bootstrap animation, which then bootstrap the hair to achieve the desired animation effect.
I can animate splines without Oratrix. It’s totally fine.
Adopt External Guides node this C4D only uses the oratrix system as a reference, not the finished spline animation as a reference, so before using this feature, there is a step to let oratrix identify the External spline animation, that’s the question that’s bothering me.

I'm a bit confused about what you are showing in the video but I will try my best to explain the two alternatives that you have in this case.

  • You have animated curves and you want to create hair from those curves.

           You can accomplish this by using the Hair from Curves preset. To generate hair from animated curves:

  1. select all the curves,
  2. go to Ornatrix menu, 
  3. Click Add Hair
  4. Select "Hair From Curves" preset and click Generate

 

  • You want to animate an existing Ornatrix groom using already animated curves.

           Animated curves can be used to deform an existing groom using Adopt External Guides modifier:

  1. Convert the animated curves to an Ornatrix object like I describe in above
  2. Select T-Pose(Static) guides as reference
  3. Select the animated guides as Control Guides. 

Adopt External Guides documentation:

Try any of the two methods and let me know if you have further questions.

What my video demonstrates is that when I don’t use splines to generate leads, Adopt External Guides works. When I changed the way to generate Guides at the ornatrix level in “Control Guides, ”“Reference Guides, ” to the mode of generating Guides again with splines, “Adopt External Guides” stopped working, and the original hair could not be driven.


I’m not quite sure, how to create a guide line with a spline animation, and then use Adopt External Guides to drive the hair I want, to get it going, and this is how I create it in my video. This is probably the wrong approach. I really don’t know how to create “Control Guides” and “Reference guides, ” and I’m confused.


Can you help me record a short video, or a sketch project like mine? Thank you very much!
