Hey guys, new day, new problem.
So I need to initialize compositing tags, a lot of them. They need to have different states concerning "seen by camera", "seen by reflection", etc. but their object buffers need to be the same.
I started with one object and one tag for testing things:

import c4d  
from c4d import gui  
#Welcome to the world of Python  
  
def main() :  
  
object = doc.GetActiveObject(False)  
tags = object.GetTags()  
for item in tags:  
if item.GetType() == c4d.Tcompositing:  
item[c4d.COMPOSITINGTAG_ENABLECHN0] = True  
item[c4d.COMPOSITINGTAG_ENABLECHN1] = True  
item[c4d.COMPOSITINGTAG_ENABLECHN2] = True  
item[c4d.COMPOSITINGTAG_ENABLECHN3] = True  
item[c4d.COMPOSITINGTAG_ENABLECHN4] = True  
item[c4d.COMPOSITINGTAG_ENABLECHN5] = True  
item[c4d.COMPOSITINGTAG_ENABLECHN6] = True  
item[c4d.COMPOSITINGTAG_ENABLECHN7] = True  
item[c4d.COMPOSITINGTAG_ENABLECHN8] = True  
item[c4d.COMPOSITINGTAG_ENABLECHN9] = True  
item[c4d.COMPOSITINGTAG_ENABLECHN10] = True  
item[c4d.COMPOSITINGTAG_ENABLECHN11] = True  
  
item[c4d.COMPOSITINGTAG_IDCHN0] = rendertag[c4d.COMPOSITINGTAG_IDCHN0]  
item[c4d.COMPOSITINGTAG_IDCHN1] = rendertag[c4d.COMPOSITINGTAG_IDCHN1]  
item[c4d.COMPOSITINGTAG_IDCHN2] = rendertag[c4d.COMPOSITINGTAG_IDCHN2]  
item[c4d.COMPOSITINGTAG_IDCHN3] = rendertag[c4d.COMPOSITINGTAG_IDCHN3]  
item[c4d.COMPOSITINGTAG_IDCHN4] = rendertag[c4d.COMPOSITINGTAG_IDCHN4]  
item[c4d.COMPOSITINGTAG_IDCHN5] = rendertag[c4d.COMPOSITINGTAG_IDCHN5]  
item[c4d.COMPOSITINGTAG_IDCHN6] = rendertag[c4d.COMPOSITINGTAG_IDCHN6]  
item[c4d.COMPOSITINGTAG_IDCHN7] = rendertag[c4d.COMPOSITINGTAG_IDCHN7]  
item[c4d.COMPOSITINGTAG_IDCHN8] = rendertag[c4d.COMPOSITINGTAG_IDCHN8]  
item[c4d.COMPOSITINGTAG_IDCHN9] = rendertag[c4d.COMPOSITINGTAG_IDCHN9]  
item[c4d.COMPOSITINGTAG_IDCHN10] = rendertag[c4d.COMPOSITINGTAG_IDCHN10]  
item[c4d.COMPOSITINGTAG_IDCHN11] = rendertag[c4d.COMPOSITINGTAG_IDCHN11]  
break  
  
c4d.EventAdd()  
if __name__=='__main__':  
  main()

The strange thing is, that it sometimes works, and sometimes I get this error message:
"TypeError: __setitem__ expected c4d.BaseList2D, not bool" concerning one (not always the same) COMPOSITINGTAG_ENABLECHN -states.
I also tried to allocate with values from other rendertags and there I get something just the other way around "TypeError: __setitem__ expected bool or int, not c4d.BaseList2D"
Would be really glad if someone could explain this behavior to me.
cheers
Phil

Hi, where do you define _rendertag _?

Hehe, sorry I forgot to update the code.
Nevermind the "rendertag", I have fixed values there like:
item[c4d.COMPOSITINGTAG_IDCHN0] = 1
item[c4d.COMPOSITINGTAG_IDCHN1] = 2

I don't have problems with these, just with the enabling of the buffers.
Sorry again for the incorrect code.

I created a Compositing Tag, and executed the following code

import c4d
from c4d import gui
#Welcome to the world of Python
  
def main() :
  
    object = doc.GetActiveObject() #removed False for R13
    tags = object.GetTags()
    for item in tags:
        if item.GetType() == c4d.Tcompositing:
            item[c4d.COMPOSITINGTAG_ENABLECHN0] = True
            item[c4d.COMPOSITINGTAG_ENABLECHN1] = True
            item[c4d.COMPOSITINGTAG_ENABLECHN2] = True

            item[c4d.COMPOSITINGTAG_ENABLECHN4] = True
            item[c4d.COMPOSITINGTAG_ENABLECHN5] = True
            item[c4d.COMPOSITINGTAG_ENABLECHN6] = True
            item[c4d.COMPOSITINGTAG_ENABLECHN7] = True
            item[c4d.COMPOSITINGTAG_ENABLECHN8] = True

            item[c4d.COMPOSITINGTAG_ENABLECHN10] = True
            item[c4d.COMPOSITINGTAG_ENABLECHN11] = True
            break
  
    c4d.EventAdd()
if __name__=='__main__':
    main()

All buffers of the attached Compositing Tag are enabled. Which version do you use? Have you the latest version of your C4D installation?

Cheers, Seb

Yep using the latest version 13.029.
I don't get it, if I create new scenes and new tags it seems to work. If I open older scenes it sometimes gives me the error messages.
I've attached a file where it works on one object(Level1) and on the others it doesn't (Levels2.1, 2.2). It works if I activate and then deactivate the buffers.
http://dl.dropbox.com/u/1262854/\_C4D_stuff/composite_tag-test.zip

Anyway most times it works now, and I inserted some exceptions, so I have direct feedback If something goes wrong.
Thanks for looking into it, maybe I just have some messed-up scenes (some of them are from R9.5).

I can reproduce this. When the scene is from version 9.5 it might be that the datatypes at these IDs were updated and so they are not valid anymore.

__setitem__ of BaseList2D checks the datatype before they are set. When they are incompatible this call raises an exception. Actually obj[id] is recommended but in this case check out the following code which (force) overwrites the data of your tag. See following example:

import c4d
from c4d import gui
#Welcome to the world of Python
  
def main() :
  
    object = doc.GetActiveObject() #removed False for R13
    tags = object.GetTags()
    for item in tags:
        if item.GetType() == c4d.Tcompositing:
            bc=item.GetDataInstance()
            bc.SetBool(c4d.COMPOSITINGTAG_ENABLECHN0, True)
            bc.SetBool(c4d.COMPOSITINGTAG_ENABLECHN1, True)
            bc.SetBool(c4d.COMPOSITINGTAG_ENABLECHN2, True)
            bc.SetBool(c4d.COMPOSITINGTAG_ENABLECHN3, True)
            bc.SetBool(c4d.COMPOSITINGTAG_ENABLECHN4, True)
            bc.SetBool(c4d.COMPOSITINGTAG_ENABLECHN5, True)
            bc.SetBool(c4d.COMPOSITINGTAG_ENABLECHN6, True)
            bc.SetBool(c4d.COMPOSITINGTAG_ENABLECHN7, True)
            bc.SetBool(c4d.COMPOSITINGTAG_ENABLECHN8, True)
            bc.SetBool(c4d.COMPOSITINGTAG_ENABLECHN9, True)
            bc.SetBool(c4d.COMPOSITINGTAG_ENABLECHN10, True)
            bc.SetBool(c4d.COMPOSITINGTAG_ENABLECHN11, True)
            break
  
    c4d.EventAdd()
if __name__=='__main__':
    main()

Great that works, thank you very much.
