SOLVED How to load a file with python and turn it into the active document ?

Hi!

I am a total beginner in python ... so this might be easy 🙂

I am using C4D Release 20 and looking for a way to import files and then work with the files as if they where actually in my C4D Editor. With that I mean I want to work with those CallCommands etc. I know that´s not the pro way but... I am not a pro yet 😉 Down below you se the code so far.

The issue now is that this line:

c4d.documents.LoadDocument(sk_doc, loadflags = 0)

...does not really load the file into a state where I can work with it. At this point my editor still shows my empty "BaseDocument" and if I try to "GetActiveDocument" I get a FALSE boolean return. So for python I still have loaded nothing it seams.

I allready tried all sorts of other "loading" methods as you can see here:

So somehow I think I need to get the loaded file out of some obscure hidden "position/state" into the state of the "ActiveDocument". So I added those lines here:

c4d.documents.InsertBaseDocument(sk_doc)
        c4d.documents.SetActiveDocument(sk_doc)

But with them I get a "TypeError: argument 1 must be c4d.documents.BaseDocument, not str"

And I have no idea how to change the file URL into a "c4d.documents.BaseDocument"-Type...

Any idea anybody?

Thanks!

        sk_doc = file
        print sk_doc
        c4d.documents.LoadDocument(sk_doc, loadflags = 0)
        c4d.documents.InsertBaseDocument(sk_doc)
        c4d.documents.SetActiveDocument(sk_doc)

        # Set Render Settings
        c4d.CallCommand(600000098) # Projectname_As_Rendername
        c4d.CallCommand(12161) # Edit Render Settings...
        renderdata()[c4d.RDATA_RENDERENGINE] = 300001061 # Use Hardware OpenGL
        renderdata()[c4d.RDATA_XRES] = 400 # X Render Resolution
        renderdata()[c4d.RDATA_YRES] = 400 # Y Render Resolution
        renderdata()[c4d.RDATA_FRAMERATE] = doc[c4d.DOCUMENT_FPS]
        renderdata()[c4d.RDATA_FRAMESEQUENCE] = 3 # Preview Range als Render Range

... much more but irrelevant code for the current issue...

I have replied your post at C4DCafe.

"The c4d.documents.LoadDocument returns you a BaseDocument, which you then need as argument for the InsertBaseDocument and SetActiveDocument."
