Hello folks!

Let me introduce you my new plugin, which is good solution for those people who developing file handling scripts for Cinema 4D R19 and higher.

The Batch Processor plugin allows to convert between all the 3D formats that are supported by Cinema 4D and supports User Scripts, including scripts with User Interface. Plugin installation contains several scripts that can be used as an example. Also plugin help contains all the necessary information about developing scripts with Batch Processor compatibility.

Using the Batch Processor, the developer needs to write only code part for processing the document, the plugin takes care of the rest (opening-saving file,collecting, display and saving the script results log).

Here is an example Demo Script:

import c4d
from c4d import gui

'''
Batch processor User Script Basic Example
Please follow the code comments 
https://mikeudin.net/


To add User Scipt dialog make sure:
1. Your dialog is based on gui.Subdialog class
2. Class must have a name 'UserScriptDialog'
3. Class must have a class variable 'user_script_container' to store all data on it
4. Script must have 'main' function that will be executed by Batch Processor
5. 'user_script_container' from dialog will be used as input argument for 'main' function

'''

class UserScriptDialog(gui.SubDialog):
    """
    A SubDialog to display the passed string, its used as example for the actual content of a Tab
    """
    
    STRING_FIELD = 2000
    INT_FIELD = 2001

    # define user_script_container as dictionary
    user_script_container = dict()
    
    def CreateLayout(self):

        # Add your dialog gui elements as descibed on Cinema 4D Python API
        # Please use methods which is compatible with Cinema 4D R19+ Python API
        
        bc = c4d.BaseContainer()
        bc.SetBool(c4d.QUICKTAB_BAR, True)  
        bc.SetString(c4d.QUICKTAB_BARTITLE, 'Script Options')
        self.AddCustomGui(1000, c4d.CUSTOMGUI_QUICKTAB, '', c4d.BFH_SCALEFIT, 0, 0, bc)

        if self.GroupBegin(1001,flags=c4d.BFH_SCALEFIT | c4d.BFV_TOP,cols=2,rows=1,title='Script Options'):
            
            self.GroupSpace(15, 6)
            self.GroupBorderSpace(15,5,15,10)

            self.AddStaticText(1002, c4d.BFH_LEFT, name='My String Data')
            self.AddEditText(self.STRING_FIELD, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, 0, 10)

            self.AddStaticText(1003, c4d.BFH_LEFT, name='My Integer Data')
            self.AddEditNumberArrows(self.INT_FIELD, c4d.BFH_LEFT | c4d.BFV_SCALEFIT, 80, 10)

            self.GroupEnd()

        return True

    def Command(self,id,msg):

        # Assign data to 'user_script_container' variable on any user gui interaction
        if id in {self.STRING_FIELD,self.INT_FIELD}:
            self.user_script_container['int'] = self.GetInt32(self.INT_FIELD)
            self.user_script_container['string'] = self.GetString(self.STRING_FIELD)

        return True

# On execution 'user_script_container' will be used as input argument for 'main' function. 
# if User Scipt do not contains dialog, 'main' function will be executed without arguments.

def main(data):
    
    '''
    Batch Processor adds some global variables to User Script:
    
    doc - referenced to a processed document, type: c4d.BaseDocument
    doc_index - referenced to an document index in Jobs Queue, type: int
    docs_total - total number of documents in a Jobs Queue, type:int

    op - Active Object of processed document, type: c4d.BaseObject 
    mat - Active Material of processed document, type: c4d.Material
    tp - Particle System of processed document, type: c4d.modules.thinkingparticles.TP_MasterSystem

    '''

    # All data that needed to be printed will be passed to plugin Log tab
    print 'Processed Document Index {0} from {1}'.format(doc_index,docs_total) 
    print 'Document name: ', doc.GetDocumentName()
    print 'Document path: ', doc.GetDocumentPath()
    print 'Document Active Object is ', op
    
    print 'My String data', data['string']
    print 'My Integer data', data['int']
    
    if 3 < doc_index < 7:
        # If index of processed document have a number 4,5,6
        # in this case User Scipt will return error   
        raise Exception('Error!')

Here is how it works:

I hope the Batch Processor will be the solution that will help automate your work on processing a large number of files using the Cinema 4D Python API!

You have to combine objects to null, for example:

import c4d
from c4d import gui

def smc(listy):
    null = c4d.BaseObject(c4d.Onull)

    for o in listy:
        o.InsertUnder(null)

    res = c4d.utils.SendModelingCommand(command = c4d.MCOMMAND_JOIN,
                                    list = [null],
                                    mode = c4d.MODELINGCOMMANDMODE_ALL,
                                    bc = c4d.BaseContainer(),
                                    doc = doc)
    return res[0]

def main():
    obs = doc.GetActiveObjects(0)
    doc.InsertObject(smc(obs))
    c4d.EventAdd()

if __name__=='__main__':
    main()

How to use this tool with objects grouped in a single null?
Not working with Figure primitive :

Traceback (most recent call last):

    ValueError: Invalid object length.

Just in case. Using my Target4D plugin you can drop your object to any surface

May be there is unicode symbols problem. Try this

f = open(fn.decode("utf-8"))

@bentraje You have to edit your
"C:\Program Files\MAXON\Cinema 4D R20\resource\modules\python\libs\python27\c4d_init_.py"
file by adding all symbol ID's as module variables.

Check out an example file, make sure you have a backup!

Hello guys! Hope you find it interesting.
I've written little script which sends copied text to differents web pages for search.
This script will be very helpfull to work with Cinema4D online SDK directly from Script Manager or Expression Editor.

Download for free here.

@klints2
Try to use IsolateObjects

A helper routine to copy the objects of document to a new document (returned). All materials associated are also copied over and the links are corrected.

Hello guys!
I've created little solution to send python code to execute in Cinema 4D. Also it works for editing Pyton Generators, Effectors, Tags and Fields! Thanks for Remote Code Runner - Cinema 4D & Sublime Text plugin by NiklasRosenstein.

Download SendPythonCodeToCinema4D

May be Polygonize can help you.

Make a clone of the document and turn all objects into polygon based objects.

@milkliu Aescripts.com, for example. I'm selling there.

@m_adam same issue with bz2 and gzip modules

@m_adam Thank you!

Hi there!
While testing my plugins foung that zlib python module not loading on MacOs BigSur 11.1 on R23.110.
On Windows 10 same C4D version it works fine.

>>> import zlib
Traceback (most recent call last):
  File "console", line 1, in <module>
ImportError: dlopen(/Applications/Maxon Cinema 4D R23/resource/modules/python/libs/python37.macos.framework/lib/python3.7/lib-dynload/zlib.cpython-37-darwin.so, 2): no suitable image found.  Did find:

Hello folks!
I need that my main Command plugin dialog react on some edits in Cinema 4D Preferences.
How it possible to track? Watching with Timer or maybe there is some CoreMessage() trick?
thank you!

Thank you @m_magalhaes !

Hello!
Just found that the python API command

c4d.CallCommand(12557) # Select Connected

In Cinema 4D R22-23 in UV Editing Mode is not working as expected. Selects all UV polygons, instead polygons on a same UV island like on previous versions. Any idea how to fix that?

@lasselauch said in Plugin not loaded in R23 on macOS:

if you want to chime in and report your findings... I'm pretty much lost here...

Sure. I'll recieve more info about client system and make some tests with my buddy who have Mac

@mdr74 OK, thank you! Will check it.

Great! Thank very much @m_adam!

Hi there!
I need to get c4d.DESC_NAME of choosen modelling settings parameter.
Here is a how it works for C4DAtom:

cube = doc.SearchObject('Cube')
description = cube.GetDescription(c4d.DESCFLAGS_DESC_0)       # Get the description of the cube object
for bc, paramid, groupid in description:                    # Iterate over the parameters of the description
   print (bc[c4d.DESC_NAME], bc[c4d.DESC_IDENT],paramid ,groupid) 

Also there is a Document Snap settings:

for bc in c4d.modules.snap.GetSnapSettings(doc):
    print bc

The result is:

(440000121, 1)
(440000120, 31.0)
(440000138, 0)
(431000002, 1.5707963267948966)

(1007, 1)
(1008, 1)

There is a way to recive Description "container" for Modelling Settings?
Thanks!
