I am writing some scene assembly tool using C4D and c4dpy.

I am bringing in Alembic cameras and other geometry assets.

On the commandline.exe, there is no option to specify which camera I can render with so I am wondering if there is some python call I need to make to the C4D document before saving so that when I render the file, it knows which camera to use ?

Cheers

Hi,

Is there a call to c4d to ascertain if there are unsaved changes in the current session. The current session was started from opening a file from disk.

I am using R21 on Windows and using Python.

Hi,

I read that I can get the RenderData object via

rdata = doc.GetActiveRenderData()

I see that frame range values are documented here

https://developers.maxon.net/docs/Cinema4DPythonSDK/html/modules/c4d.documents/RenderData/index.html?highlight=renderdata

RDATA_FRAMEFROM
RDATA_FRAMETO
RDATA_FRAMESTEP

Cheers

Hi,

I am reading the following

https://developers.maxon.net/docs/Cinema4DPythonSDK/html/modules/c4d.gui/GeDialog/index.html?highlight=addeditnumberarrows#GeDialog.AddEditText

hoping there might be some directory browsing UI.

My intention is to allow the user to pick an output directory for some processing.

Cheers

Hi,

I have difficulty keeping the label for a edit UI component on the same line with the following code. I want the FRAME_CHUNK_EDIT to the right of FRAME_CHUNK_LABEL

    def CreateLayout(self) :
        '''
        Frame Chunk size,
        Render folder prefix
        Frame range (start, end)
        '''
        self.GroupBegin(id=1013, flags=c4d.BFH_SCALEFIT, cols=1)
        #
        self.GroupBegin(id=1014, flags=c4d.BFH_SCALEFIT|c4d.BFV_SCALEFIT, cols=1)
        self.AddStaticText(FRAME_CHUNK_LABEL, c4d.BFV_MASK, name="Frame Chunk size")
        self.AddEditNumberArrows(FRAME_CHUNK_EDIT, c4d.BFV_MASK, initw=100)
        self.GroupEnd()
        #
        self.AddButton(SUBMIT_BUTTON, c4d.BFV_MASK, initw=100, name="Submit")
        self.GroupEnd()
        return True

Cheers

@m_adam said in Unable to update Alembic path in xref:

Unfortunately, there is no built-in way to control MessageBox within Cinema4D.

The only way for you is to install a 3rd party python package, here a possible one https://github.com/asweigart/pyautogui.

Maxime.

But I am running the script with c4dpy, there is no UI.

Is there something I can call in c4dpy to tell the current active session to default to "Yes", it seems that c4dpy defaults to "No"

Cheers

DESCFLAGS_SET_USERINTERACTION

Using DESCFLAGS_SET_USERINTERACTION there was a prompt in my script.

Update XRef (Yes) or replace (No)?

How do I respond (Yes) in my script ?

Cheers

I have the following code which was able to get the path but can't update the path

flags = c4d.SCENEFILTER_MERGESCENE | c4d.SCENEFILTER_OBJECTS | c4d.SCENEFILTER_MATERIALS

active_doc = c4d.documents.GetActiveDocument()
merge_status = c4d.documents.MergeDocument(active_doc, target_scene, flags)
assert(merge_status)
# Model[c4d.ID_CA_XREF_FILE]
obj_name_to_search = 'Model'
xref = active_doc.SearchObject(obj_name_to_search)
alembic_path = xref.GetParameter(c4d.ID_CA_XREF_FILE, c4d.DESCFLAGS_GET_NONE)
print(alembic_path)
status = xref.SetParameter(c4d.ID_CA_XREF_FILE, animated_alembic_file, c4d.DESCFLAGS_SET_PARAM_SET)
assert(status)
if True:
    c4d.documents.SaveDocument(active_doc,
                            target_scene,
                            c4d.SAVEDOCUMENTFLAGS_0,
                            c4d.FORMAT_C4DEXPORT)

Hi,

I have been using GetNext() and GetDown() to perform depth first visit of the scene. That works fine.

I wish to now perform some operations a a given hierarchy level.

Is there some GetNodeListsAtCurrentLevel() type of methods ?

I am using the Python API with R21

Cheers

OK, I will use the support forum.

Yes, using "Add XRef..." still result in seeing the Alembic Settings pop up every time I open the file.
