Polygon selection tag to vertex (weight) map

Hi all!
Been trying to get my script ready that simple makes a vertex map tag based on a polygon selection.
Inside c4d you do this with the Set vertex map command. But inside python it works a little different I think??Setting the vertex map is with:
vertexmaptag.SetAllHighlevelData(selection tag values here)But how do I set the selection tag to be the value to make to weight tag?
After that I also like to do an smooth weight command. Tips on that are also welcome!All help is appreciated!
Thanks!

As the name vertexMap is per vertex and not per polygon.
Anyway here is an exemple I made for set/read weight data in python

Thanks for the example script!:)
Still a question (No expert I have to admit
)How do I read in my selection tag to be the value of the weight map?

Hi,
assuming you have a polygon selection stored in a SelectionTag, get the BaseSelect from the SelectionTag (GetBaseSelect()). This BaseSelect stores the selection state per index (of points, polygons,...), see for example IsSelected().
In case the selection is not stored in a SelectionTag, but is only an active selection on a PolygonObject, then you can get the BaseSelect via GetPolygonS().
Now, as gr4ph0s already pointed out, when having a polygon selection, you will need to find out the points/vertices belonging to a selected polygon. Via PolygonObject.GetAllPolygons() (or GetPolygonR() or directly via GetPolygon()) you get the CPolygon structure of a polygon, which stores the point indeces you are looking for.
