for brackets i don't know, haven't really seen them the console font is so tiny. the snippet is
directly from the console, c4d put them there. for accepting the path - does c4d accept double
backlashes instead of single ones ? after __add__ the raw string is transformed into the
escaped form and rdata[pathblah] actually contains the double backlashes.

There are no double backslashes in the string. There are double-backslashes in the output because
you didn't print the string. See Python's __repr__.

Hey Guys,

I checked again:

if i change

doc.GetActiveRenderData()

back to

doc.GetActiveRenderData().GetData()

and

documents.RenderDocument(doc, renderData.GetData(), renderBmp, c4d.RENDERFLAGS_EXTERNAL)

to

documents.RenderDocument(doc, renderData, renderBmp, c4d.RENDERFLAGS_EXTERNAL)

Thers no file output to disk anymore, just pictureviewer

Is that weird?

It is indeed. Could you provide an SSCCE?

I read your link, but i'm not too sure what that's supposed to be ^^sorry

would it not be an option to simply send you the code? or the plugin? because i don't think it can be trimmed to far and i don't know how to make it work without all the parts. Does that even make sense?^^

SSCCE = Short Self Contained Correct Example

=> Just paste some code that shows the problem and can be run right in the script
manager or in a Python plugin-file.

You can also send it via PM if you don't want to make it public.

Hey NiklasR,

Here is what i belive to be a SSCCE:

  
  
import c4d  
from c4d import gui, plugins, documents  
import os  
  
if __name__=='__main__':  
      doc = c4d.documents.GetActiveDocument()  
      renderData = doc.GetActiveRenderData()  
      xResolution = int(round(renderData[c4d.RDATA_XRES]))  
      yResolution = int(round(renderData[c4d.RDATA_YRES]))  
      pathChange = False  
  
      if renderData[c4d.RDATA_PATH] != "":  
          storedPath = renderData[c4d.RDATA_PATH]  
          renderData[c4d.RDATA_PATH] =r'{0}_{1}'.format(renderData[c4d.RDATA_PATH], "extension")  
          c4d.EventAdd()  
          pathChange = True  
  
      renderBmp = c4d.bitmaps.BaseBitmap()  
      renderBmp.Init(x=xResolution, y=yResolution, depth=32, )  
  
      result = documents.RenderDocument(doc, renderData.GetData(), renderBmp, c4d.RENDERFLAGS_EXTERNAL)  
      if pathChange == True:  
          renderData[c4d.RDATA_PATH] = storedPath  
      if result==c4d.RENDERRESULT_OK:  
          c4d.bitmaps.ShowBitmap(renderBmp)     # show image in pictureViewer

Just create a new scene, save the renderoutput in some folder. If you run this script, the rendered file will actually be output to the folder. If you move the .GetData() to doc.GetActiveRenderData().GetData() and remove it from renderData.GetData(), theres no more file output.

Hi Amadeo,

yes that is perfect, thanks.

I'm also very confused, I can reproduce the behavior you describe. I don't see what is wrong
in your code, mine works (see below). Anyway, you could still just save the image by hand. The
script below is doing this as well so you will end up with two images when the Save parameter
is checked in the render-data.

import os
import c4d
  
def main() :
    rdata = doc.GetActiveRenderData().GetData()
 **    # rdata[c4d.RDATA_SAVEIMAGE] = False**
    xres = int(round(rdata[c4d.RDATA_XRES]))
    yres = int(round(rdata[c4d.RDATA_YRES]))
  
    path = rdata[c4d.RDATA_PATH]
    if not path:
        c4d.gui.MessageDialog("no save-path specified")
        return
  
    dirname = os.path.dirname(path)
    if not os.path.exists(dirname) :
        os.makedirs(dirname)
    elif not os.path.isdir(dirname) :
        c4d.gui.MessageDialog("destination directory can not be created.")
        return
  
    path = '%s_extension' % path
 **    # rdata[c4d.RDATA_PATH] = path**
    fileformat = rdata[c4d.RDATA_FORMAT]
  
    bmp = c4d.bitmaps.BaseBitmap()
    if bmp.Init(xres, yres, 32) != c4d.IMAGERESULT_OK:
        c4d.gui.MessageDialog("could not allocated bitmap for render.")
        return
  
    result = c4d.documents.RenderDocument(doc, rdata, bmp, c4d.RENDERFLAGS_EXTERNAL)
    if result != c4d.RENDERRESULT_OK:
        c4d.gui.MessageDialog("rendering was not successful, see console.")
        print "rendering failed with error-code", result
        return
  
    result = bmp.Save(path, fileformat)
  
    if result != c4d.IMAGERESULT_OK:
        c4d.gui.MessageDialog("rendered bitmap could not be saved, see console.")
        print "saving bitmap failed with error-code", result
  
main()

It seems to be the setting of the RDATA_PATH, because when you uncomment the red line,
the RenderDocument() function does not save automatically anymore.
