How can I set, through programming, the corners of the Interactive Render Region?
Thank you very much in advance for any reply.

Perhaps these?

I found those. But aren't those for the final render?
I mean in the editor screen. Where are those stored?

the size of the interactive Render Region is stored in the active BaseView. This is internal data and might not be save to be edited by third parties.

See "Get size of the IRR?"

Hello Sebastian.

I did found that thread. However, it is for reading.
How can I write to that internal data structure?

as you can see in the linked thread the information is stored in a subcontainer. You can edit this subcontainer and write it back into the given data instance. Calling c4d.EventAdd() can then be used to inform Cinema that something changed.

Best wishes,

What are the IDs of the parameters, so that I can store new values there?

Give this a try Rui.

import c4d  
def main() :  
  #Get the Editor window  
  bd = doc.GetActiveBaseDraw()  
  if bd is None: return  
  #Get it's size in pixels  
  size = bd.GetFrame()  
  #Get it's container(the master container)  
  bc = bd.GetDataInstance()  
  if bc is None: return  
  #Get the subcontainer entry that holds the IRR  
  subcontainer = bc.GetContainer(430000020)   
  #Change the left corner positions of the IRR  
  subcontainer.SetReal(0, 0.0)  
  subcontainer.SetReal(1, 0.0)  
  #Update the master container to use the changed subcontainer values  
  bc.SetContainer(430000020, subcontainer)  
  #Print the IRR's 4 corner positions  
  for i in subcontainer:  
if __name__=='__main__':

Thank you very much, Scott. It works perfectly 🙂
