We are using Arnold with C4D

While iterating the scene, we have found that one of the node (create via the ArnoldtoC4D plugin), the GetNext() method does not return the next object but itself, this resulted in an infinite loop iterating the scene.

Since we are now sitting between two different vendors, I am trying to narrow it down to who I need to follow up with regarding this issue.

>>> doc = c4d.documents.GetActiveDocument()
>>> obj = doc.GetFirstObject()
>>> print(obj)
<c4d.BaseObject object called 'Arnold distant_light/Arnold Light' with ID 1030424 at 0x0000027ACD423D10>
>>> obj.GetNext()
<c4d.BaseObject object called '<display driver>/Arnold Driver' with ID 1030141 at 0x0000027ACD423AD0>
>>> obj.GetNext()
<c4d.BaseObject object called '<display driver>/Arnold Driver' with ID 1030141 at 0x0000027ACD423FB0>
>>> obj.GetNext()
<c4d.BaseObject object called '<display driver>/Arnold Driver' with ID 1030141 at 0x0000027ACD423DF0>
>>> obj.GetNext()
<c4d.BaseObject object called '<display driver>/Arnold Driver' with ID 1030141 at 0x0000027ACD423AD0>
>>> obj.GetNext()
<c4d.BaseObject object called '<display driver>/Arnold Driver' with ID 1030141 at 0x0000027ACD423FB0>
>>> obj.GetNext()
<c4d.BaseObject object called '<display driver>/Arnold Driver' with ID 1030141 at 0x0000027ACD423DF0>
>>> obj.GetNext()
<c4d.BaseObject object called '<display driver>/Arnold Driver' with ID 1030141 at 0x0000027ACD423AD0>
>>> obj.GetNext()
<c4d.BaseObject object called '<display driver>/Arnold Driver' with ID 1030141 at 0x0000027ACD423FB0>
>>> obj.GetNext()
<c4d.BaseObject object called '<display driver>/Arnold Driver' with ID 1030141 at 0x0000027ACD423DF0>
>>> obj.GetNext()
<c4d.BaseObject object called '<display driver>/Arnold Driver' with ID 1030141 at 0x0000027ACD423AD0>
>>>

@zipit There was a typo when updating to use the new IDs generated from Maxon, it has since been resolved and the plugins are loading.

Cheers

I am currently using this approach to iterate the objects in a document

doc = c4d.documents.GetActiveDocument()
obj = doc.GetFirstObject()
next_obj = obj.GetNext()
while next_obj:
# Do stuff
next_obj = obj.GetNext()

Is there some equivalent of doing this via e.g. indexing in a for-loop ?

Cheers

I have generated the IDs from the site you recommended.

When I replace the plugin IDs with those generated from https://plugincafe.maxon.net/c4dpluginid_cp the menu would not even load.

I have a dialog button which hangs when I click it but it only hangs for a specific scene.

From looking at the printout in the python console window, it appears that when I click the 'Submit' button, it never reaches the call to Command()

TTR_PLUGIN_ID = 999121032
TTR_CANCEL_BUTTON = 12003
TTR_SUBMIT_BUTTON = 12004

    def Command(self, id, msg):
        print('TurnTableRenderDialog::Command()')
        print('id = {}'.format(id))
        print('TTR_SUBMIT_BUTTON = {}'.format(TTR_SUBMIT_BUTTON))
        if (id == TTR_SUBMIT_BUTTON):
            print('TTR_SUBMIT_BUTTON')

    def CreateLayout(self):
        '''
        Frame Chunk size,
        Render folder prefix
        Frame range (start, end)
        '''
        self.SetTitle('Submit turn table to Tractor (PlutoWithDamage)')
        self.GroupBegin(id=1013, flags=c4d.BFH_SCALEFIT, cols=1)
        #
        self.GroupBegin(id=1014, flags=c4d.BFH_SCALEFIT, cols=2)

        self.AddStaticText(TTR_COMMENT_LABEL, c4d.BFV_MASK |
                           c4d.BFH_RIGHT, name="Comments")
        self.AddEditText(TTR_COMMENT_EDIT, c4d.BFV_MASK |
                         c4d.BFH_LEFT, initw=400)

        self.AddStaticText(TTR_FRAME_RANGE_LABEL, c4d.BFV_MASK |
                           c4d.BFH_RIGHT, name="Frame range (start,end,step)")
        self.GroupBegin(id=1015, flags=c4d.BFH_SCALEFIT, cols=3)
        self.AddEditNumberArrows(TTR_FRAME_RANGE_START, c4d.BFV_MASK, initw=100)
        self.AddEditNumberArrows(TTR_FRAME_RANGE_END, c4d.BFV_MASK, initw=100)
        self.AddEditNumberArrows(TTR_FRAME_RANGE_STEP, c4d.BFV_MASK, initw=100)
        self.GroupEnd()

        self.GroupEnd()
        #
        self.GroupBegin(id=1016, flags=c4d.BFV_MASK | c4d.BFH_RIGHT, cols=2)
        self.AddButton(TTR_CANCEL_BUTTON, c4d.BFV_MASK |
                       c4d.BFH_RIGHT, initw=100, name="Cancel")
        self.AddButton(TTR_SUBMIT_BUTTON, c4d.BFV_MASK |
                       c4d.BFH_RIGHT, initw=100, name="Submit")
        self.GroupEnd()

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.

Cheers

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
