View Full Version : Attaching a transform to a vertex
Hello, several times I've been in the need to attach a transform node to a vertex. I thought, i could do it in the connection editor but it doesn't work. Anyone?

I assume you're just looking for a way of controlling that single vertex? If that's the case I'd probably say just hook a cluster up to it and re-matrix the cluster to a locator or empty null for an easier method of moving it about.
Thanks for replying. Actually it's the other way around, I want to drive the locator's motion(and orientation) through the vertex, so i could for instance, attach a button to piece of cloth, or a rig control at a specific position on the face.

you should look at the follicle node, you can attach that to a surface or mesh. if you then parent your locator to that follicle, you'll have what you need.

Gotcha, well in that instance you could use a rivet to fixate the locator to the position of the vert and have it follow, my suggestion would be to use a single nurbs plane as your rivet piece and a pointOnSurface node if you need the utmost control (this will allow you a large amount of flexibility operating U and V). If you want to just work directly with a poly mesh, look up the closestPointOnMesh command and plug-in which should allow you to get the desired result (more effective than a normal or geometry constraint I find).
Seem interesting, I'll givem a look and see how it works. Thanks.
I found the follicle node in the docs, but how do I create it? Excuse my ignorance. Meanwhile i'll take a look at ther other solution.
*And also, how am I supposed to find that out by myself?(creating the follicle node) (it's a serious question).

Follicles are part of the hair system, essentially all you have to do is generate a curve and then make it dynamic from the hair menu. This, for all intensive purposes turns the curve into a 'follicle'. If you look a bit further into the documents in Maya 8 there's a sort of indepth explanation of the hair system and a tutorial.

please guys do a quick search before posting question, this is asked every week and had been answers a thousand time.
PS: if you don't have unlimited, search foor the rivet.mel Script.
Your right, I could've sworn i searched before posting. Your totally exagerating about that answer frequency though.
Posted by brentorama:
select the cv at the end of your curve and go dynamics -> Emit from selected. Delete the particle, keep the emitter and that's your point constraint daddy for your claw parent. Then do a tangent constraint with the curve and the claw parent, eet shood verk no?
That is soo elegant. I' ll try that.
