Couldn't you just update the compositing project file with new links?

Still, this feature sounds a great implementation to Renomi. Will try to implement it. Thanks for idea.

Hello Tomas,

could you please post an example of your suggestion updating the composition file?

You can simply run another thread with the renomi plugin in which you check if the rendering is still running.
After the rendering is finished you can do the sorting stuff.

it could be done better but this one as a starting point:

import c4d  
  
import os,time, thread  
  
  
def isRendering(time,os) :  
  
  print(time.ctime())  
  
  while c4d.CheckIsRunning ( c4d.CHECKISRUNNING_EXTERNALRENDERING ) :  
      print("render in progress...")  
  
      time.sleep(4)  
    
  print(time.ctime())  
  print("render complete.")   
  
  
def main() :  
  
    
  c4d.CallCommand(12099)  
    
  if c4d.CheckIsRunning ( c4d.CHECKISRUNNING_EXTERNALRENDERING ) :  
      thread.start_new(isRendering,(time,os))  
  
if \__name\_\_=='\__main\_\_':  
  main()

Hi there. It is possible.

There are a few issues you'll need to address to make this happen:
- regex to split up the file name so you can get the multipass type ( object buffer, diffuse, etc ) I would use http://regex101.com to help you get that all figured out. From there, you can isolate the multipass name and create the directories based on those names.

- How you're going to move/overwrite the files ( new directory or a re-render ). I would recommend shutil.copy2 for both moving and overwriting files. I had issues with shutil.move. Also, you'll want the files that you're going to move in a list and move that list only. Rinse and repeat until the render is done.

try:
    if path.exists( existingFile ) :
        print "    Overwriting " + existingFile
        shutil.copy2( fullPath, newDir )
        os.remove( fullPath )
    else:
        print "    Moving " + f
        shutil.copy2( fullPath, newDir )
        os.remove( fullPath )
except IOError as e:
    print "    File may have already been moved"
except WindowsError as f:
    print "    File may have already been moved or permission denied"

- I would recommend moving files every so many seconds during the render to avoid a massive pileup of transferring 10000+ files once the render is complete.

 while renderCheck == True:
        time.sleep ( 5 )
        renderCheck = c4d.CheckIsRunning ( c4d.CHECKISRUNNING_EXTERNALRENDERING )

Hopefully this is enough to get you going.
Have fun!

Hello Herbie,

thanks for the lines.
Unfortunately that was not the problem I mentioned.
I´m allready able to rearrange the rendered pictures,
but I was searching for a way to update the compositing file (e.g. the after effects file), in a way that
it updates the changed filepasses of the renderpasses.
Do you have a solution for this issue?

Best wishes
Martin

Hi Monkeytack.
I was talking about Compositing Project File (aec), and not the actual composition file.
In AEC file just replace the paths and you are good.

Sorry monkeytrack, I was responding to soupman99.. didn't realize the original post was months old.

As for the AE file. If you're not updating the aec file and just want to update the passes in the AE project, you can save out an aepx file ( XML file ) from AE and replace the paths there. This will allow you to do all of the scripting in python.

If you don't want to save out an aepx file, you can use regex to parse the current sequence and get the multipass name, then append it to it's filepath. Once that's been rebuilt, use .replaceWithSequence in AE to replace the footage. This approach will need to be done in javascript though..

Hi,

@Tomas
Following your suggestion, I can change the file ~~but the redered pictures could´nt be found in Ae.~~
~~What did I miss?~~
''''EDIT
If the compositing file is inside the renderpasses folder the code will work, great so far!! Thanks
Do you know which part of the string I´ve to change to store the compositing file and the renderpasses in different folders?

The File structure:
['CINEMA 4D COMPOSITION\r\rRESOLUTION 800 600\rFROM 0\rTO 10\rRANGE 91\rFPS 30\rFIELDS NONE\rASPECT 1.000000\rVERSION 7\r\rCOMPOSITION NRM ON "change files"\r{\r STEREONUM -1\r FSEQ NRM LINEAR PREMUL ON RGB NMLF NOPARENT -1 -1 "/User/blablubb/Desktop/AE_CHANGE_TEST/new_folder/change files0000.tif"\r}\r\r']

  
  doc = c4d.documents.GetActiveDocument()  
  RenderData = doc.GetActiveRenderData()  
  path_re=  RenderData[c4d.RDATA_PATH]  
  
  path=os.path.dirname(path_re)  
  dirList=os.listdir(path)  
    
  #let´s say this is the compositing file  
  fname = str(path+"/"+dirList[1])  
  
  #open file and read the stored string  
  with open(fname,'r') as f:  
      content = f.readlines()  
      f.close()  
  
  #set up the replace string  
  replace_path = "/User/blablubb/Desktop/AE_CHANGE_TEST/new_folder/change files"  
  new_str = content[0].replace( path_re, replace_path)  
  content[0]=new_str  
  
  #write the new file  
  f =  open(fname,'w')   
  f.writelines(content)  
  f.close()

Thanks in advance

@Herbie
again thanks,
both ways require that I open Ae, which I don´t want, am I right?
Anyway, could you please show an example script?
Thanks in advance

Hi Monkeytack. I am not sure I understand what you are asking.

Let's take it from the top. Once you render from Cinema 4D image sequences, AEC Compositing Project File is placed to sake folder where Main pass goes. Here's how my AEC file looks like:

  
CINEMA 4D COMPOSITION   
  
RESOLUTION 800 600   
FROM 0   
TO 10   
RANGE 91   
FPS 30   
FIELDS NONE   
ASPECT 1.000000   
LOCAL   
VERSION 7   
  
COMPOSITION NRM ON "main"   
{   
STEREONUM -1   
FSEQ NRM LINEAR PREMUL ON RGB NMLF NOPARENT -1 -1 "/Users/Tomas/Desktop/render/MAIN/main0000.tif"   
}   
  
FSEQ <-> LINEAR PREMUL ON RGB NMLF NOPARENT -1 -1 "/Users/Tomas/Desktop/render/PASS/PASS_blend_1_0000.psd"   
  
CAMERA "Camera"   
{   
SHOWFROM 0   
SHOWTO 10   
KEY 0 600 300 -600 45 -19.45 0 53.130102 1000 1   
KEY 10 600 300 -600 45 -19.45 0 53.130102 1000 1   
}

Now. If you rename your Main pass images or put them in another folder, just change the path

FSEQ NRM LINEAR PREMUL ON RGB NMLF NOPARENT -1 -1 "/Users/Tomas/Desktop/render/MAIN/main0000.tif"

to something else. For that use some clever RegEx or something.

Same goes for Multi-pass sequence folder - just update the links and save the file.

Does that help?

EDIT
If you change the name of you Main pass images (in my case it's main0000.tif) to something different like XXX0000.tif, then you also have to update the COMPOSITION NRM ON "main" to COMPOSITION NRM ON "XXX" in same AEC file.

Hi Tomas,

if you analyze the code i´ve posted, you might have seen that I do it the same way you´ve described it.
Whitout using re module ok, but it should work anyway.

I change the search path of the rendered pictures.

But this only works, if the compositing file(aec file) is inside the same folder as the rendered pictures.
For whatever reason.
It should work, even if I move the aec file later on to another folder, too.

I guess I miss something. Any idea?
Could you please post a working example for comparison?

Thanks in advance
Martin

What error are you getting? That files are missing when import AEC file to AE? Right?
After Effects should load AEC file no matter where that AEC file is, as long as all paths, linking to images, exist.

Are you sure you are updating COMPOSITION NRM ON "change files" line in AEC file to match your new name if you are renaming image sequences? change files - > NEW NAME

Can you try updating AEC file manually and check if AE loads files OK?

And I am sorry I cannot upload you a working example from Renomi, as there were 3rd parties involved in writing this part of the code.
