@mdr74 Done!
Please download new version and let me know how it works.

@adam_k_garner sure it solved my issue

Thank you @m_adam!
Here is code for C4D lower vesions support:

import ctypes

def message(id,data):
    
    if id == c4d.MSG_DRAGANDDROP and c4d.GetC4DVersion() >= 23000:
        ctypes.pythonapi.PyCapsule_New.restype = ctypes.py_object
        capsule = ctypes.pythonapi.PyCapsule_New(b"", b"data", None)
        data["data"] = capsule

Have a same issue.
There is a workaround to avoid Error messages?

@r_gigante Ouch! thank you!

Hello,
I am currently trying to complete a plugin for R23 in Windows 10. After compiling the code I distributed the plugin to several people and they were able to successfully run the plugin with the exception of one person. The one exception gave this error.

WARNING: Error loading file:///C:/Users/MyUser/AppData/Roaming/Maxon/Maxon Cinema 4D R23_DBA5903C/plugins/MyPlugin/R23/MyPlugin.xdl64: Could not load dll because of

How can i fix that?

Hi @r_gigante! Thanks for your ansver. We working together with @Danchyg1337 on this project.

Here is a little demo what happens when Deformer works with generator object (like Cube, Sphere, Plane etc.) in Isoparm Display mode.

https://drive.google.com/open?id=16GpN1otRIdRPaIlw4yHFctC0GW1k0tCO (video)

Cinema 4d crash happens only if deformer is applied to generator object, with polygon object it works as expected.

@m_adam Thank you!

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!
