couple a cube with the polygon structure of a figure

Posts: 6
Hello guys,
I have a Problem I need to set cubes relative to the polygons of a figure.
Therefore I created a cube as a child node of the head from the Gneral2Female Model to test it. Now I can move the head and the cube moves, too... thats good. But I need to morph the Gesture with parameters and the cube´s have to move.
In the first picture I set the cube manually. Thats a position I need. And now if I set the poison parameters of the eye brows the cube don´t move and is in the second picture behind the eye brow on the old position.
Is there a way to couple the cube on a polygon of the figure, with the result that the cube move automatically to he right position?
Have anyone of you a good idea?

no need anymore.
I am asked to give you this advice
And I thought I was a nerd, that last bit went ZOOM right over my head...
Getting the movie munchies ready ... want to see more of this show!
And Possibly a repeat of the intro I obviously missed, "why" are we doing 'what' is being done?
Have figure, cubes, not a problem.
Using RIgid follow node, eg we can set earling as child of the Node which assigned Ear poligon.
which can auto follow head rotation, and can follow head morph too.
without Rigid follow node, set earling as child of Actor Head, then use head shape morph,
the earing position can not follow well. then we need manually adjust positon.
(or may need to make ERC morph to adjust earing positon which can follow the morph shape)
With set Rigidity group Editor options, you can decide how the node follow polgions deform
eg, you can set earing keep vertical pose. (rigid follow node keep groval rotation value,
when head rotate.) when Actor rotate head.
I deleted all my pics , because there is miss understanding to using "rigidity group editor option".
I hoped not confuse OP by my pics. (it set rigid follow node as head of Actor)
after check "someone" reply , I understand, I needed to set Rigid group node as child of genesis root.
but I set RIgid follow node as child of genesis head.
though it could follow head rotation, and morph without problem, if set rigidity follow node
as child of head node, rigidity editor option setting could not work anymore.
I hope to know about option of rigidity gorup editor " rotation"
"secondary, primary" clear meaning. it seems not work as I expected.
eg I hope to only restrict groval rotation of Y , but I could not find the way clear.
(then I simply felt strange, why someone needed to use admin to offer his knowledge?
I thought someone might not hope to reply under me.
Then I decide not disturb froum member anymore. maybe someone not hope me try to answer
without clear knowledge and strange pics. and I understand I always claim daz offer documents.
I decided I never reply any technical topic. and if I need to ask something, may use support center,
or google with forum to find right answer.
Nooooo!!!!!!!!!!
The second post was absolutely right. I´d tested it and it worked great!
I can now say ty to you. I played with the parameters and the node followed in the right way all the time.
I don´t rlly understand why you deleted it just because the reply.
I think it isn´t not so hard to check for me I have to set the node as a child of genesis xD.
Well, maybe I try to reissue the post for next users, who still have the same problem.
Hi...So I tried Chohole's instructions for creating rigid follow nodes to parent stitches to so that they could flex with expressions. I successfully made the nodes, one on either side of the mouth, and parented the stitches to them. See top picture. As soon as I add an expression, though, the stitches fly off the head. See bottom picture. What am I doing wrong???

Not my instructions, just something I was given to advise the OP. sorry :red:
Yeah but he feels misunderstood now :P. Okay what ever.
Here´s my reissue now from the second post I hope everybody can follow this short tutorial.
Okay at first I set a new Scene with the Genesis2Female Model. To create a follow node, you only need to follow these Intsructions:
1.) select the Figure (here it is the Genesis2Female Model) then click on tool settings on the right side (Maybe it isn´t open so you have to click in the top menu (window->panes(tabes)->tool settings) and the window will open.
2). Make shure the Geometry Editor is selected, otherwise select it.
3.) Now you can click on the polygon you need. After your right choice do a right click and select Geometry Assignement->Create Rigid Follow Node from Selected. After that a popup will apear and you have to enter a name for the new Node.
4.)As you can see it in picture 4 I named my Rigid Follow Node leftlabialangle. I want to show the followering from an object with a Sphere. Therefore I created a Sphere (top menu create->new primitve) and bring it in the position I needed, did a right click on the created Sphere and slected "change Parent".
5.) The next Picture shows the last Step. In this Step I selected the Rigid follow Node (leftlabialAngle) as new Parent and accepted it.
6.) Now how you can see it in the last Screenshot the Sphere follows correctly the labail angle and its done.
I hope this post will help you. I have to say I hate statements like you have to do a forum or google search!!! Because if you have a damn problem all forums say to you do a google search or something like that... and so the posts are only a lot of Spam in the internet. Mostly the top entries in search machines.... Plz plz don´t do it.
I sent the notes to the mods/admins in a "report" of the thread... to point one of them in the right direction. It was never intended to be posted verbatim. The intent was for a mod/admin with more time than I have to participate in threads that are likely to need several responses, to use the notes as a brief guide [like it was quickly scribbled on a napkin] and then explain it in more detail. I read the forums regularly... but I don't always have time to respond. Quite simply... I didn't want to leave a user hanging... but I didn't have time to respond in a way that wouldn't just lead to more questions.

Which node you parent a Rigid Follow Node to plays a significant part in how that node will transform (i.e. rotate, translate, scale). Parenting a Rigid Follow Node to the node of the figure that has the most influence on the reference geometry will allow the majority of the rotation/translation to be inherited from the parent... making the transition more predictable.
The axis options in the Rigidity Group Editor is [perhaps too] complicated for the average/casual user... and is probably more likely to be used in a trial and error fashion; yes, I'm well aware that visual feedback of some sort would make this much easier to understand. Basically, we're using linear algebra to determine arbitrary vectors for a given set of vertices. Each axis is calculated using singular value decomposition (SVD). As a simplification [, which for some I'm certain will not be simple enough]...
Primary - Given a set of vertices, this is the vector along the greater dimension of a plane created from the average of those vertices
Secondary - Given a set of vertices, this is the vector along the lesser dimension of a plane created from the average of those vertices; perpendicular to Primary
Tertiary - Given a set of vertices, this is the vector that is perpendicular to a plane created from the average of those vertices; perpendicular to Primary and Secondary; a "normal" if you will

whoa! you come on back kitakoredaz!!! I never saw your post having dropped by after you had edited it out apparently :-(
You often have very valid approaches to matters and are a valued contributor IMHO. If you feel because you've made a decision, well use one of my 'woman's prerogatives" to change mind. I got lots ;-)
Hey Bubbsi -- I followed your instructions exactly, the only difference being that I am trying to parent multiple items to a single node. No matter what I do, the stitches fly off the face and do not conform to expressions. [See screencaps in previous post.] Any recommendations?
