So, lets assume that a scene has complex dependancies.
A generator depending on a splinewrapper, depending on a spline, depending on a oSweep, etc. etc.

How do i succesfully collapse such constructs to editable poly in a python script? My approach would have been to make a dependancy tree and then navigate from the leafs inwards.

But how do form that graph?

I know about about

objectInfo = obj.GetInfo()
if objectInfo & c4d.OBJECT_INPUT:

But i need to know which Object is the parent of that Input. Or preferably, if there is a existing solution a pointer to that?

Or is there a sort of generic, generator dependency tree that can be traversed?

Sorry, solved itself, the project path was not added to the jdk table file of pycharm. After that pycharm stopped doing this.

<additional ASSOCIATED_PROJECT_PATH="$USER_HOME$/LocalProjects/your/project/folder" SDK_UUID="0c6c6d76-ff0d-40a3-b9de-d6146d25c014">

Hi everyone,

hope you had nice holidays.
im trying to follow the pyCharm setup, explained here and here:
https://developers.maxon.net/docs/Cinema4DPythonSDK/html/manuals/introduction/autocompletion_dummy_package.html

https://plugincafe.maxon.net/topic/10961/how-to-use-c4dpy-for-cinema4d-r20-sp1/4?_=1673858332967&lang=de

The problem is, as soon as the Interpreter is called it seems to get stuck and start the interpreter over and over. Spamming my system with c4dpy instances in the background, with roughly a new one ever 3 minutes.

Anyone experienced similar problems?

Hi everyone, hi ferdinand,

simple question, is there a way to unify a objects normals (inward facing, outward facing) in code and flip them?

I know about the OLathe FlipNormals Boolean, but found that these is not a reliable indictor for inwards or outwards facing normals.

Is there a way to get the outwardness and inwarndness of normals (points majority towards pivot or away from pivot)..

And is there a modifier (sorry for the 3ds max term) that flips all normals for editables.

Hi, i have a crash of the corona plugin and the resulting callstack in your bugreport. So after reporting it to Chaos, i decided to investigate the whole thing myself.

Turns out the crash is during a FileRead for the Converter.logo in KernelLand in windows.
Which should be easy to investigate with the

GetLastError()

if you have a minidump of the process. Which we have, thanks to bugreport not only consisting of x64 registers and stacktraces.

https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-readfile

So my question, were in the minidump attached to what dll is the error return value of the failed operation?

I assume its in the process block of the dll, but without source i can only guess. So can i get the hexadress of the position in the dump that corresponds to the error number.

To much coffee, to little sleep, so forgive the typos.

Hi manuel, thanks for the quick reply.
It seems thats the source of most of my probelms. I tried to solve it with preconversion, that picks out specific objects and applies a conversion strategy, but this will become lots of boiler plate busy work, though it may be worth it for performance reasons.
Trying the isAliveApproach now.

Same problem encountered with Ocasurface.

When converting objects in bulk, i run into a problem with R23.

The Code in which it crashes:

			for objectList in objectLists:
				try:
					commandCount += 1
					
					result = c4d.utils.SendModelingCommand( 
						command = c4d.MCOMMAND_MAKEEDITABLE,##CMD.MAKE_EDITABLE
						list = objectList,
						mode = c4d.MODELINGCOMMANDMODE_ALL,
						doc = doc,
						flags = c4d.MODELINGCOMMANDFLAGS_CREATEUNDO # if this flag is not set the method will delete all affected objects from the list and return them
					)

					LogWithTimestamp(commandCount * objectsPerCommand, " items of ",len(allObjects)," made editable", LogLvl.DEBUG)
etc.

I add the crash report zipfile. I have no idea how to fix it, though it seems to be a kind of stackoverflow..

_BugReport.zip

I reduced the number of objects converte to narrow down what crashes the script. It blows up during the conversion of a Circular Object called "Kreis" which is a inner Object of a oSweep Object.

During handling of the above exception, another exception occurred:

I tried to work around the problem, by preconverting all oSweeps and oLathes, but even then once the script hit the circle Spline Object, it errored out in send Modelling command.

If i convert a complex object, i guess i must clean up below.
Still should just convert to a polygon circle then.

Have a nice evening.

Thanks alot Ferdinand.

I investigated some further and added the classes to the plugins list:

_plugins = [
    "Tools",
    "Recipe",

The error was also caused, by the executables having different libraries. Meaning, we call once cinema 4d.exe, which uses the {prefs}/python39/libs folder.

The second part of the plugin is executed using the classic Commandline.exe and uses the {prefs}_x/python39/libs folder.

Im a idiot, but a stubborn one.
Have a great day.

Topic can be locked now.

So, to answer my own question, seems that importing module components without module qualifiers does no longer work in 3.9?

from Tools import LogWithTimestamp is wrong

from VC4D.Tools import LogWithTimestamp is the correct way to go

Hi everyone,

im trying to upgrade our python module from R21(Python27) to the most recent cinema version 2023.1.0. BuildNumber (CL387487.470010)

I followed the instructions on the website, https://developers.maxon.net/docs/Cinema4DPythonSDK/html/manuals/misc/python3_migration.html

I copied the library-module to the following paths:

c:\Users\tov\AppData\Roaming\Maxon\Maxon Cinema 4D 2023_BCDB4759_x\python39\libs\

C:\Users\tov\AppData\Roaming\Maxon\Maxon Cinema 4D 2023_BCDB4759\python39\libs

C:\Users\tov\AppData\Roaming\Maxon\python\python39\libs

The library components are not found with the error message:

Traceback (most recent call last):
  File "C:\Program Files\Maxon Cinema 4D 2023\plugins\vuframe-aura-commandline.pyp", line 31, in <module>
    import VC4D.Recipe as Recipe
  File "C:\Users\tov\AppData\Roaming\Maxon\Maxon Cinema 4D 2023_BCDB4759_x\python39\libs\VC4D\Recipe.py", line 11, in <module>
    from Tools import LogWithTimestamp
ModuleNotFoundError: No module named 'Tools'

The base plugin which uses the librarys resides in

C:\Program Files\Maxon Cinema 4D 2023\plugins

My module contains the usual suspects required:

__init__.py
__main__.py
_version.py

What did i miss?
Is it required to add a special Path to the systemvariables?

Hello everyone,
i think i have a problem with the floating license model.

https://support.maxon.net/hc/en-us/articles/4409883337874-Floating-licenses-in-Maxon-App

In particular it seems that in this license state machine, there is no state dedicated to what happens to licenses, when programs execution aborts suddenly or connection is lost. Is there a collection mode, were i can start releasing licenses from a pool that are currently not in use? Or a time-out were a license returns to pool after n minutes?

I had to release licenses from defunct instances manually which sort of defeats the whole purpose of automation & scripting.
Is there a way to have a "always on" program on the running maschine, to auto-release the license, should it loose connection or time out?

Im sorry, i can not send you the customer files. As soon as the team has any time, we will reproduce the test case in a seperate 3d file and send it with the code-sample.

@ferdinand Thanks for your reply Ferdinand.

One converted out example looks like this, having no resemblance to the original object which was a cable in a spiral. Some other examples exist, were the spiral is sqashed into a eardrum like shape.

It seems the spiral modifier data structure (which should be a sinus applied over a 3dimensional circle ) is squashed into a 2dimensional concept. You can even see a second sinus multiplied in at the end.

I shall try to use the Modelcommand recommend by you. Sorry for the slow replying.

The object will be converted, but will be turned into a sinusoid polygon editable.

Used command:

MAKE_EDITABLE = 12236

doc.SetActiveObject(obj)
c4d.CallCommand(MAKE_EDITABLE)

I exported the scene pre and post operation and it is actually this command producing the result.

The sweep Object is a pretty standard cable with diameter and a spline to trace.

Thx to all of you for reading and helping. Pretty great comunity.

Eh, this was the first approach i tried, it will map the decoded utf-8 to Windows codepage 1252. (Sorry about the wrong one in the code above). I tried to change the system setting to utf8 but it would not accpet that. Thanks for your help, Maxime

Not certain it solves your problem but in this post somebody changed the preview picture in python.

Hi, i encountered a problem using paths containining Umlauts in my code. Im trying to rename Customer Texture files which have Umlauts in there names.

I traverse the folder, glue the filenames together which does not produce any error.

originalFilePathAsciiiUTF8Mix = os.path.join(srcFolder, 'tex', originalFileName)

However when i try to use the concated path, with file.open or shutil.copy2 the path is not found and the displayed path in the error message seems to be a strange mixture of properly escaped ascii symbols and not escaped UTF8 elements.

I printed out the path as hexValues and the values look like a classic ascii (no codepage) string (not clear on what codepage) and raw UTF8 Values in the middle.

Example:

originalFilePathAsciiLatin1 -> |C=43|:=3a|\=5c|T=54|e=65|s=73|t=74|\=5c|I=49|n=6e|p=70|u=75|t=74|\=5c|4=34|3=33|4=34|6=36|9=39|\=5c|4=34|3=33|4=34|6=36|9=39|\=5c|t=74|e=65|x=78|\=5c|k=6b|i=69|e=65|f=66|e=65|r=72|_=5f|g=67|e=65|f=66|l=6c|=c3|=a4|m=6d|m=6d|t=74|_=5f|1=31|.=2e|j=6a|p=70|e=65|g=67

So ive read into encodings and utf8 in Python 2.7 and boy, what a rabbit hole.
My question is, how can i convert this "hybrid" into a valid utf8 representation and finally into a path that the services used by shutil and os.copy can handle.

originalFilePath = originalFilePathAsciiiUTF8Mix.decode('utf-8').encode('cp1250')
os.copy(originalFilePath, sanitizedFilePathName)
