Hi,

i want to add a custom object buffer to my render settings.

i was only able to add an "empty" channel yet. maybe there is some issue in the GetDataInstance() - using the wrong object or something similar.

buffer = c4d.BaseList2D(c4d.Zmultipass)
buffer.GetDataInstance()[c4d.MULTIPASSOBJECT_TYPE] = c4dd.MULTIPASSOBJECT_OBJECTBUFFER

this seems not to be enough to initialize the channels as a Object Buffer. Maybe there is some kind of init function needed?

other channels like specular / mat_uv / etc working fine

Maybe this will help?

is there anyway to remove an object buffer from the multipass list? I only saw functions for adding

Thanks!

The MP gui is a tree gui gizmo similar to the OM gui.
You can traverse through it the same way you traverse through the OM tree. And get one of the children.
Then you can edit or delete that specific child object.

#This is how to delete a specific Object Buffer  
  
import c4d  
def main() :  
  
  rd = doc.GetActiveRenderData()  #Get the render settings  
  mp = rd.GetFirstMultipass()     #Get the first Multi-Pass item  
    
  #The Multi-Pass option is a tree gui type gizmo like the OM tree  
  #Use GetNext() to step down to get each child object in the tree  
  #Either one at a time...or with a loop  
  if mp.GetTypeName() == "Object Buffer":   #<---The topmost object in the tree gizmo  
      firstBuffer = mp  
      secondBuffer = mp.GetNext()  
      thirdBuffer = secondBuffer.GetNext()  
        
      if secondBuffer is not None: secondBuffer.Remove()  
        
  rd.Message(c4d.MSG_UPDATE)    #Tell c4d you changed the render settings      
  c4d.EventAdd()

Oh that makes sense. Wish the would make that more clear in the documentation. Thanks Scott!
