you are not passing a valid path arguments to the LoadFile method. listdir returns a list
of the file names for the given folder path, not the file paths contained in in a folder path.

please use [KODE]mycode[/KODE] flags for your code (code written with c instead of k).

Yeah i figured it out, i have to take the whole file path. Its now working, but it opens each obj in its own document. i want to merge it into the same document like the import function. is there a way without merging documents together? this is the only solution i find in the docs.

yeah it is obviously loading each file into seperate document, i thought this was intentional.
to merge the file with your current document either use c4d.documents.mergedocument or
c4d.documents.loaddocument. the first method just works like the command know from the
c4d file menu, while the second method does not do any loading, but returns a BaseDocument.
you would have then manually search and insert the data from the returned BaseDocuments

hi littledevil,

not sure what is meant with that. just merge the documents in an iterative fashion or use the
loaddocument method and do it manually.

def Execute(self, doc) :
...
res = True
for path in pathlist:
	res = res and documents.MergeDocument(doc, path, c4d.SCENEFILTER_OBJECTS)

edit:

it might be necessary that you send a message to the hosting basedocument each time
you merge a document with the hosting document before you merge the next document
(see basedocument.sendinfo). haven't done such mass merging yet. if it still fails to work
for multiple documents simply use loaddocument and add the objects/ materials manually.

ok i tried the way to read the first doc ad merge it with the active (which is the last opened) with this code but nothing happened. no failure an no merging.
def Execute(self, doc) :
path=c4d.storage.LoadDialog(c4d.FILESELECTTYPE_ANYTHING, "Please choose the folder", c4d.FILESELECT_DIRECTORY)
dirList=os.listdir(path)

for fname in dirList:
openName = os.path.join(path, fname)
print openName
r = c4d.documents.LoadFile(openName)

firstDoc = c4d.documents.GetFirstDocument()
activeDoc = c4d.documents.GetActiveDocument()
print firstDoc
print activeDoc
c4d.documents.MergeDocument(activeDoc, firstDoc, c4d.SCENEFILTER_OBJECTS)# | c4d.SCENEFILTER_MATERIALS)

use codetags and read the documenation. MergeDocument accepts a BaseDocument for the
hosting document variable and a string path or MemoryFileStruct for the document to merge.
you pass two BaseDocuments.

also your approach will open multiple docments within c4d, which is apparently not your goal.
the reason why you are not getting any result is, that you do not read/print the MergeDocument
result. It will be always False, as your second parameter is not in the expected format.

Give this a try.
It should load all of the .c4d scene files, .obj files, etc. in the selected folder
