Hi all,

I'm trying to get a short hair style to blow in the wind.  I have no issue with the longer hair styles, but when I try it on shorter styles (I've tried a few different ones), I always get the same result:

The hair seems to explode off of the head and then just fall to the ground.  I've uploaded an example here:

Can anyone help me figure out how to get this working? 

Thanks!

Loool! This is not the desired effect but it's quite funny to watch

The weight map must be related to the UV unfolding of the model. Depending on how it's made, it's more or less complicated. Each strand of hair has to have the end in white to move, and the base in black to be fixed ...

Pixtim'Store : Motions and models (marketplace and preview)

FaceBook group : Pixtim for Reallusion Iclone and CC3

The Fly away effect is caused by the collision cage setting causing it to move away from the cage. and the weight map settings as Pixtim stated. you need UV mapped hair and MUST have a pure black part to attach the hair to the head.

mrl,

As noted... it depends on how the hair is unwrapped.

But.... No matter how it's laid out... One Way to ensure awesome results is...
View the hair in an uv editor... you will be able to (Easily) create the physics weight map, because you can see the "Roots"

Example:
View in a uv editor:


Select a small section in the uv editor and LOOK at the character to see if it's THE ROOT.



Keep selecting until you find ALL OF THE ROOTS.



Now create a template to paint your map in your favorite image editor.

_____________________________________________________________________________________________________________________________

REALLUSION make this easier to do because of "HOW THEY PAINT IT.
Look at the "Dark Spots"


Paint those dark spot (Solid Black and use various "Lighter" shades and BLEND from solid black to white.


This is down 'n dirty (Quickly Done)... but it works.

Do you use Blender or similar 3rd party 3d modeling / animation program??

That's amazing!  Thanks for the detailed reply. 

Unfortunately I'm pretty new at some of this more advanced stuff.  I do have Cinema 4D, but I'm far from proficient at it (to be honest, I'd never heard of a UV editor until now).  Looks like I have some learning to do but this gets me a huge step in the right direction. 

I'm assuming I need to learn how to use the C4D UV editor and then with that and Photoshop I can more-or-less follow the steps you've laid out above, yes?

Thanks everyone for the replies!

In 2D Space... you use the coordinates (X & Y) to pin-point a spot. (Location)
In 3D Space... you use the coordinates (X,Y,Z) to pin-point a spot. (Location)

A "Mesh"... is the surface of all objects. It has "Vertices" joined by line segments.
(Forming the shape).
The shapes are squares, known as "Quads".... these quads are split into "Triangles."
"Quads and Triangles" form "Faces" along the mesh.

To texture a mesh.... a "Shader" is applied to all of the "Faces" 
Light strikes the surface and the shader goes to work (displaying the texture applied).
____________________________________________________________________________________

BUT...

How do you texture any object? You paint or place an image over the "Faces."
How does any program know where the faces are?????

The software needs to know (exactly) where each "Vertex" is.
Remember... in 3d space, the coordinates (x,y,z) are used to pin-point a spot. (Location)
BUT....
To find a vertex.... a different coordinate is used. (U,V,W) SPACE.

In UVW Space:
A mesh is (Unwrapped - Flattened)... displaying EVERY vertex and face.
THIS (flatten image) is a 2d representation of the mesh.
THIS is the mesh's UV'S.

You send this 2d uv "Template" to your image editor.
You overlay..."Paint or Place Images" on it to accurately texture it.

Hope This Helps.

That's incredibly helpful!  Thanks again for taking the time.

You're W E L C O M E! 

You have C4D... Please dive (Head First) into it and learn her tools.
A million offers will come your way to "automate" this or that.
....don't buy it. Learn C4D.

Practice:
Modeling - (Box, Spline, Patch, Nurbs)
Rigging - (Humanoid, Quadruped, Robotic)
Animating - (Learn the Function Curve Editor)... inside out.

Then when you get inspired and say, "Hey, I want it to do this and look (Exactly) like that.
The BEST PART IS: You do NOT start from scratch... you learn to:
Make that face have the (Unique Features)... you want.
Conform (SkinWrap) this mesh to that one.
Blend ANY animation (mocap, bvh, fbx).... with precision.

C4D will take you to the promise land.
Guaranteed. 

Sounds like a plan!
