Parameter wiring i max

[MathTheRender]

is there a possibility to wire a dummy to a certain vertex of a spline? maybe with a specific modifier which would give me access. i cant find any documentation...

anybody?

"Linked Xform" is what you are looking for.

ok. thats a great tip. i dident kowed that modifier before. but i like it to have the influence the other way around. a vertex of a spline (wit a noise applied) is supposed to influence a dummy objects position.

Spline ik control?
Skin maybe?
I'm not sure if they'll do it - i've not got time to check.

[MathTheRender]

i already tried skin, and with spine ik i can just controll the vertexes wit the helpers spline ik creates and not the other way around.
althou i dont really understand why i can show the vertex numbers in the edit spline mod but not access them individualy....

[Resolution01]

You have got me thinking. It you animate the spline vertex it create three variables Invec, Vertex and OutVec. It you change the Vertex controller to XYZ you could wire them to the XYZ of the dummy. This might work, i haven't tried it.

You can use the Attachment Controller to do just that.

@ Instinct: i have to apply an edit poly modifier to the spline so i can catch the object in the attachment controller. so far so good. but when i apply an noise modifier the dummy starts to jump around and won't stick to a defined place.

@Resolution01: i don't understand where i could find the dialog to set an XYZ controller to a certain vertex. where i occasionally apply the controller, i just have access to the position of the whole spline. since i can't script in max, i feel now pretty cornered.
so i hope i just didn't cope it well, and you may explain it again to me, because it sounds like a solution so far

beside: i saw that xsi in the release 2012 just got an extrude modifier (lol), so maybe they could exchange some knowledge to the max people how gettin' access on single vertexes

yesterday i found this, but sadly, when i tested it this morning in max 2012 it does not work.

but it looked really promising

I guess the issue is rather the source beeing a spline, which i also overlooked in your post sorry. That one seems to do the same as an attachment controller?
If you want to specifically lock to a spline's vertex i'd say use a script controller and read the position of the said vertex. You should be able to find its ID within
an editable spline mod's subobject mode. For Meshes attachment works perfectly fine tho, so you might want to consider adding a sweep (or turning on renderable).
Then it should work fine. It does not properly work with the Edit Poly because that does not generate a stable mesh (and might sometimes not produce a mesh at all).

thanks, Instinct, that was a very valuable tip wit the sweep modifier, now the attach controller works stable, even when i play around with the noise mod! the script i found still keeps on jingeling and does not work in my case.
the script controller sounds the most accurate, but i would use it the first time, and therefore just don't know how to work with it, and what the code would be...

but the tip wit the sweep and attach controller works fine for me.
thank you very much!
