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!🙂

    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?

    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.
