Hi all
after solving my last Problem (thanks to nux95 )

Here a second Question:
How can I define the value of the Phong-Tag?
It should bo on an the angle should be 35° (0,61)
I catched something out of the Skript log and modified it.
But, it does' t work!

  
def setAllPolygonObjectsPhongTag(doc) :   
    obj = doc.GetFirstObject()   
    while obj:   
        if obj.CheckType(c4d.Opolygon) :   
            c4d.SetActiveTag(c4d.Tphong, 0)     <------------   
            c4d.PHONGTAG_PHONG_ANGLELIMIT=True <------------   
            c4d.PHONGTAG_PHONG_ANGLE=0.611      <------------   
            obj.SetBit(c4d.BIT_ACTIVE)   
        else:   
            obj.DelBit(c4d.BIT_ACTIVE)   
        obj = walk(obj)

Does anybody has an idea???
Thanks
Rgds

c4d.PHONGTAG_PHONG_ANGLELIMIT and 4d.PHONGTAG_PHONG_ANGLE are just constant ID (Integer values).  
You can't just set them to another value (ok, they are not really constant, that's because of Python)  
and hope this will change the attribute of the tag. How should c4d know what object you mean ?  
  
You can use either the comfortable way, using \__getitem\_\_ and \__setitem\_\_, that implement  
the [] bracket syntax, or the uncomfortable but mor flexible way using a BaseContainer.

# the comfortable way using [] syntax (__getitem__, __setitem__)  
    import c4d  
    import math  
      
    obj[c4d.PHONGTAG_PHONG_ANGLELIMIT] = True  
    obj[c4d.PHONGTAG_PHONG_ANGLE}      = math.degrees(35)  
      
    # note that this syntax is all equivalent with  
    obj.__setitem__(c4d.PHONGTAG_PHONG_ANGLELIMIT, True)  
    obj.__setitem__(c4d.PHONGTAG_PHONG_ANGLE, math.degrees(35))

# the more flexible but uncomfortable way  
    import c4d  
    import math  
      
    bc  = obj.GetData()  
    bc.SetBool(c4d.PHONGTAG_PHONG_ANGLELIMIT, True)  
    bc.SetReal(c4d.PHONGTAG_PHONG_ANGLE, math.degrees(35))  
    obj.SetData(bc)  
      
    # not that when calling `obj.GetDataInstance()` instead  
    # of `obj.GetData()` you obtain the **original** c4d.BaseContainer  
    # instance, so you do not have to call `obj.SetData(bc)` afterwards.

Most things in live are so easy

The solution is:

obj.SetPhong(1,1,0.610865238)

and it works

Glad you found the solution.

Be aware that the first and second parameters aren't numbers, but booleans (True or False, like a checkbox). So you could call SetPhong() like this: obj.SetPhong(True, True, 0.610865238)

And thanks for pointing out this method, its documentation is broken Confused . I'll fix it.

In your code, obj is not the phong tag, it is still the polygon object.
Just like the c4d module does not know what tag you want to affect, when you wanted to do c4d.PHONGTAG_PHONG_ANGLELIMIT = True, the polygon object doesn't know either.

Obtain the phong tag using

tag = obj.GetTag(c4d.Tphong)  
if not tag:  
  # the object does not have a phong tag  
  continue # go to the next loop  
tag[c4d.PHONGTAG_PHONG_ANGLELIMIT] = True  
# ...

_And I have to correct something from above, of course you need to use math.radians and not math.degrees. _
