Thank you for your detailed explanation, it shed some light on the whole matter for me.

Apologies in advance if this question is out of scope.
Is the Maxon API already fully usable for Python, or can it completely replace the classic API? I find it very difficult to understand right now. Or is it more intended for initializing data types and using it in conjunction with the classic API?
And if not, when will it finally be fully usable for Python?

@i_mazlov
Thank you very much for the hint with the texture view and for the helpful links.
The second thread I have already read, but was not able to find the solution so far. I study these examples. Thank you.

Hi,
I am not able to get the TempUVHandle from an active UVWTag in R21.
It returns always "None".
In the following script I created a simple plane in a TempDoc and took the cache and inserted it into the TempDoc. It already has a UVW-Tag, then I have set the object active and so the UVWTag....

My Code:

import c4d

def main():
    temp = c4d.documents.BaseDocument()

    plane = c4d.BaseObject(c4d.Oplane)
    temp.InsertObject(plane)
    temp.ExecutePasses(bt=None, animation=False, expressions=False, caches=True, flags=c4d.BUILDFLAGS_NONE)
    
    plane_cache = plane.GetCache().GetClone()

    if plane_cache is None:
        raise Exception("no cache")

    temp.InsertObject(plane_cache)
    uvw_tag = plane_cache.GetTag(c4d.Tuvw)   
    temp.SetActiveTag(uvw_tag)
    temp.SetActiveObject(plane_cache)

    handle = c4d.modules.bodypaint.GetActiveUVSet(temp, c4d.GETACTIVEUVSET_UVWS)
    
    print(handle)
    

# Execute main()
if __name__=='__main__':
    main()

@ferdinand
Thanks a lot Ferdinand for your time and effort. It is always admirable how carefully and thoroughly you answer many questions.
At first it was often difficult to understand and follow your code examples...now it is a little easier.
Thanks for that.

I found out that the following method also does the job:

c4d.SendCoreMessage(c4d.COREMSG_CINEMA, c4d.BaseContainer(c4d.COREMSG_CINEMA_FORCE_AM_UPDATE), 0)

Sorry for the second question about why this

buttonDesc[c4d.DESC_FITH] = True
buttonDesc[c4d.DESC_SCALEH] = True

in the GetDDescription method are not working. I thought this is a follow-up question.
I will open another topic for that.

Hi, in my object plugin it worked fine but in my tag plugin the description cannot be updated after clicking a button which in this example should add a new button.

so when I click the button it adds a new id to the member variable self.id_list, and then I iter through this list in my GetDDescription() method
It just shows the added Button if I click on the Object which holds the tag and select again the tag.
Do I have to send a message? I read the GitHubExample but it is a example with an ObjectPlugin.

edit by @ferdinand:

@ThomasB said:

I have also problems to scale the button so that it fits the attribute manager:

so this doesn't work in the GetDDescription Example above:

bc_measure_object_hide[c4d.DESC_SCALEH] = True
bc_measure_object_hide[c4d.DESC_FITH] = True

@ferdinand
this is really odd, because I have a Button in my plugin which simply creates keyframes for specific description parameters of the plugin, similar as it is in the PoseMorph Tag when you create keyframes for all sliders at once. And here it works without crashing:
Maybe this helps you.
The code of writing the keyframes is pretty the same, the only difference is that I set here keyframes for the description Id's instead of the user-datas...hm

this is just a snippet:

Hello,

I'm just a bit stumped. In previous versions of C4D this approach, writing keys worked perfectly.
Normally the routine is executed by a plugin in the message method, but I was able to change the example into a script and that's where the error occurs.

Here I have the script and the required scene with the object.
bake_test.zip

The script should simply write keys with values ​​into the user data, usually the user datas are animated and they are a lot more, so in the plugin it has to filter the right ones
After detailed debugging, I'm sure the error happens in the third last line with key.SetValue(curve, value)

import c4d

doc: c4d.documents.BaseDocument  # The currently active document.
op: c4d.BaseObject | None  # The primary selected opect in `doc`. Can be `None`.

An Object plugin returns an object chain with certain objects.
But now I need a point at a very specific position of the object where other objects created in Cinema 4D can snap to it.

I have or rather wanted to solve this by creating an internal polygon object that is placed in the object chain with a point, for example. I then made the point visually visible using the Draw method

ObjectData.Draw(self, op, drawpass, bd, bh)

However, the snapping does not work properly. If you're too close, nothing will snap. If the snapping radius is too small, nothing works.
Am I completely on the wrong track or should I approach the whole thing differently? Sometimes there's just a lack of new things, and I can't always find everything in the Github examples...sometimes I have to laugh at myself, how stupid I want to start a spedific approach....

Regards

@ferdinand
oh man thanks I forgot this

BaseDocument.ExecutePasses(bt=None, animation=False, expressions=False, caches=True, flags=c4d.BUILDFLAGS_NONE)

I tried that before but it seems I have set the caches parameter wrong.
Thank you very much....

Hi, sorry for this as always dumb question.

I was trying to get the Cache of a cloner object in the GetVirtualObjects(self, op, hh) method.
First I tried it in the python generator, there was already a cloner in the scene and in the python generator I returned the cache so to say, but this approach doesn´t work out in an object plugin.
Even if I create a temp_doc. The returned cache is always None.
But converting the cloner with a ModelingCommand is not the best way, if the cloner produces for instance a million clones.

This method works in a python generator when the clone is already in the scene

cloner = op.GetDown()
return cloner.GetCache().GetClone()

But creating a cloner and returning its cache doesn`t work.

cloner = c4d.BaseObject(1018544)
c4d.BaseObject(c4d.Ocube).InsertUnder(cloner)
return cloner.GetCache().GetClone()

Is there a way to get the cache in a plugin?
Sweep, Extrude, other Generators, Deformers and parametric objects work perfectly.

@ferdinand
Hello Ferdinand,
Thank you very much first of all.
yes, you're right, I worked extremely sloppily with the SMC method, of course I'll take the threading into account and also work with a Temp Document.

Regarding the problem itself, I can only say that reinstalling CINEMA 4D solved our problem.

Cheers

Hi,

for demonstration purposes, I have an extremely stripped down version (1200 LOC) of my plugin (6000 LOC) here.
Unfortunately it was not possible to insert the whole Pyp file here because the post can only be a maximum of 32767 characters long. That's why I only have sent the classes and functions that are not so important are without code.

• Condition: the window bars must be activated. Error with Boole happens in the method

def bar_cutter(op, obj, bars, fixed=False)

Description:

Of course, it is not technically perfect and in this version it is more of a prototype. I was able to narrow down the error to the Bars_Cutter() function. That's why I only included the bar_cutter method.

• In this function I read specific points from the created frame and create a spline, which I throw into an Extrude and then convert to a polygon object. this extrude is used to cut the window bars.
• I then create a Boole object and throw the previously created bars together with the extrude into the Boole object.

Normally I also create a polygon object from the Boole object with SendModelingCommand() but to prove that the error comes from the Boole, I insert the Boole object directly under the window frames.

Problem:

The problem now is this. If you reduce the arch height of this arched window, the polygons will now intersect. The following usually happens (R23-2023). The bars then simply disappear. And the glass is no longer displayed correctly either. That's actually OK. The user immediately knows that something is intersected. (Watch Video)

And in version 23-2023.2 this works, as can be seen in the video.
But in version 2024 when the polygons intersect, Cinema 4d freezes.

I have a short video to watch here.

Also the version of the plugin in a zip file for R23-2023 and 2024 for easy reference.
Boole-Problem.zip

It actually only happens when the intersection of the intersected polygons creates a slightly deformed extruder.

Question:

Why does this freeze in 2024... Version and in R23-2023 not?

Temporary Solution:

I was now able to get around the problem by calculating the points of the extrude, how many there should be if Arch Subd has a certain value. When the polygon interesects, the extrude suddenly has more points. And I'll check that. If there are more, I simply don't create the Boole anymore. Then it works......

For demonstration purposes, I only sent the content of the plugin, not the res, header and str files. These are then included in the plugin itself. I hope that's ok.

@m_adam
Thank you very much Maxime.
But there is one more thing I would like to know.
Why don't the highlighted links work? I am always referred to this site.

@m_adam
Sorry, little question, what does the python extenstion "pype" mean?

@CJtheTiger
thanks
But that doesn't seem to work because if, for example, I create an object plug-in that returns a cube in the GetVirtualObjects() method and I assign 2 objects to this plug-in in the Object Manager, then I still see the child objects in the editor window.

Do I have to set a parameter or a flag somewhere to specify the ObjectPlugin somehow?

@llealloo
That wasn't a one-way ticket recommendation, but just to test whether the problem still exists...

I can't even get the usd library installed. pip shows me errors even via venv in pycharm as well as with their .whl files.

Back to your proplem:

• Maybe it doesn't work properly because the USD module needs some dependencies that are not installed or some modules are not supported in C4D python...to my knowledge not all modules of the standard library are supported in c4d python

Hi,
Happy New Year

I have an internal development question.

How does this work, for example with Generators such as the Boole Object or Spline-Mask, when two objects are under the Bool-Object as childs, but these are no longer visible in their original form in the Editor View? But only the newly created object. They have to be hidden somehow but they are still visible in the Object Manager.

• How does this work exactly?
• Does this happen when registering the plugin with the method and specifying the info argument and type

plugins.RegisterObjectPlugin(info=type))

• Or do they have to be saved in a variable and deleted somehow or is there a Function to make them invisible?

Just to get the idea?

@llealloo
Your link is not working, with the folder example in your first post.
Have you tried to place it into a separate folder in your res-folder or directly into your plugin folder and write the path into to the sys-path?
That's just a few lines of code:

Folder structure:

• plugin folder.
• • res folder
• • your module
• • plugin.pyp

import os
import sys

# if the module is placed directly into the plugin folder - add the folder to the python search path
folder = os.path.dirname(__file__)  # your plugin folder
if folder not in sys.path:
    sys.path.insert(0, folder)

import yourmodule

But I would paste the module into the res-folder

Folder structure:

• plugin folder.
• • res folder
• • • your module
• • plugin.pyp

import os
import sys

# add the  res  folder to the python search path
folder = os.path.join(os.path.dirname(__file__), "res")  # res folder
if folder not in sys.path:
    sys.path.insert(0, folder)

import yourmodule

Yes, download the SDK and study the examples.
I wrote my own software that allows me to simply select the type of plugin I want to create, enter the plugin ID and the plugin name. The program then creates the folder structure, all files with the correct content and the correct name automatically...that was the first thing I did because it is always extremely tedious.
This then takes 10 seconds and I have a finished blueprint. Then I can start programming straight away.
I usually make the Gui first using UserData to roughly create the design and then I write it down in the resfile in no time at all. It's relatively quick and even fun and you gradually grow into it, it emerges little by little.....

Basically it wouldn't be a problem to write a script that writes the UserData interface into a Res, header and string file, I already have an idea for that... That would actually be easy to do.
I'll get to it when I'm done with my update... and then maybe make it available to the community... However, a similar one is already there, but I can't remember where.

Greetings
Tom
