Hello,

I want to stick the Null Position and Orientation to a Polygon(the red marked Polygon) from a deformated Object (source).
The easiest way would be: constrain the null to Polygon but unfortunally there is no Option in C4d.
So maybe there is a workaround via Xpresso(maybe also without Expresso?!)
Inside the ExpressoEditor I started with the source-object to find the desired Poygon Polygon Index , this Polygon has a Center and also an Orientation/Polygon Normal this values should controll the Null-Position and this already works fine.
But I am having trouble with the Rotation can anybody help?
The null will be used later for rigging! The Surface-deformer in no option.

(There is an smallC4d scene attached Stick2Polygon)

Trouble,trouble cant attache file, https://www.dropbox.com/s/g2uzpr6dlua660t/Stick2Polygon.c4d?dl=0
here is a dropboxlink

Thank you

sorry I mean Xpresso, to much Expressi today

Hi FIFTYEIGHT,

Would that work for you? Since Constrains>Clamp>Surface (I assume) isn’t working for you.

I have added a Null but the Platonic should give you already the needed data

All the best

Hello Dr. Sassi,
