Hi @ThomasB, so far SDK fixes or SDK related issues like this one were never backported to older version. We are sorry if this bother you, but this is how it was and how it will be handled in the future.

Cheers,

Hi @tdapper, the hair color preferences are automatically loaded from a file during C4DPL_STARTACTIVITY and saved within C4DPL_ENDACTIVITY, So you will need something similar for your plugin to properly serialize and load data.

If you still have issue, could you share your code, so we can have a look of what is wrong.
Thanks in advance,
Cheers,
Maxime.

Hi @HolgerBiebrach, you are right, the content browser is gone, and it is completely replaced by the Asset Browser. The correct way would be to provide a Database (the equivalent of the lib4d but for the Asset Browser) to your user, so if they are before R25 they should use lib4d, if they are in R25 they should use the database.

To do the conversion follow the next step:

1. Create a new DataBase.
   Open the Asset Browser, and click in the top menu in the 3 lines.
   Then left click in a Databases this will open a contextual menu, select Create Databases..., select a folder (an empty one) where the Database will be created.
2. Import the lib4d file.
   Go to the the Asset Browser Create menu, and click the Import Legacy Library entry, and select your lib4d file. A popup should open to select the destination Database, select the one you just created.
3. Share this Database to the user.
   zip the database folder you selected when you created the database and share it to the user.
4. (User) Load the database.
   Extract the zip file, go in the Cinema 4D Preferences, in the Asset Browser and add the extracted zip folder. Restart Cinema 4D or open the Asset Browser and go to the Edit menu -> Reload Databases. The content will be in the Converted folder.

The C++ API for the Asset Browser is available in C++, in R25 but not the Python API. The main issue is that the Asset Browser UI does not expose the URL of an Asset, but if you have an maxon.Url of an asset, you can load it the same way you did with c4d.documents.MergeDocument.

You can find an example in C++ how to load a Material within the Loading Materials from AssetDescriptions into a Scene.
Finally if you want to learn more about the Asset API I advice you to read the Asset API HandBook, to have a good overview of main classes and how things works together.

Hi @orestiskon, glad that you fixed your freeze. Replace should not freeze Cinema 4D, I would be interested to have your complete setup to reproduce this freeze.

KillDocument is needed only if you inserted the document in the list of documents (via c4d.documents.InsertBaseDocument), otherwise the Python Object is the owner of the BaseDocument, and when the Python Garbage Collector will run at the end of your scope, since no more reference of your Python Object (your variable fbx if you prefer) exist, it will delete it, and internally the BaseDocument will be freed properly.

Cheers,
Maxime.

Hi @orestiskon the way to have a document identical to what is render, is to animate the document from the beginning to the targeted frame and evaluating the document each frame. The evaluation of a document is done via ExecutePasses.

One important thing is that internally sometime Cinema 4D use several call to ExecutePasses to really have the final result. Usually calling it 3 time in a raw is enough.

There is the basedocument_animate example which demonstrate how to animate a scene, one things to note is the use of DrawView, this internally does call ExecutePass beside also refreshing the ViewPort.

Hope it helps,
Cheers,
Maxime.

Hi @chuanzhen from Cinema 4D you can retrieve preference it using the maxon module (the future proof way)

• maxon.Application.GetUrl(maxon.APPLICATION_URLTYPE.PREFS_DIR).GetSystemPath()

Using the classic API (better for back-compatibility)

• c4d.storage.GeGetStartupWritePath()

And finally if you are not within Cinema 4D you can compute it with Cinema 4D path, as demonstrated in retrieves_temp_folder_r17.py

Hi @WTools3D, unfortunately your description is a bit too fuzzy for us to be able to help you.

I have implemented NURBS object as a spline and polygon generator.
What does it mean? You have a PolygonGenerator that output spline?

If I understand you correctly your 2 questions, should help you to workaround the "several visual glitches". But can you elaborate a bit more on this topic? So we can fix the issue, or provide proper way to not have "visual glitches and problems".

2. Just return true in your draw method during the HIGHLIGHT_PASS, this way nothing will be drawn.

For the first question, I would need to understand more your plugins.

Is there a way to disable drawing spline cache object while it is part of generator object?

What do you mean by being part of the generator? If they are children of your generator, and your generator is registered with the OBJECT_INPUT then the cache should be automatically touched and therefor not shown.

But it have to be visible after it is converted to spline object.
What do you mean here? how does the conversion occurs? Is it when the user make editable your generator? If yes, you can react to the MSG_EDITABLE_END to customize the result.

Cheers,
Maxime.

Hi @César-Vonc I think you speak about Python each plugin type have a limitation of 50 (call to RegisterXXXPlugin).
So you can have 50 ObjectData and 50 TagData. But you can't have 51 ObjectData (the number of C++ plugins does not count).
Normally it should be be an EnvironmentError exception that will be raised and not an OSError.
And there is no workaround.

Cheers,
Maxime.

Hi @SteveJLV, the APPEND mode is not supported by the HyperFile.

The FILEOPEN enum is also used in BaseFile, which is the underlying class used by the HyperFile. BaseFile properly support Append mode, but extra code in the HyperFile prevent it to work correctly.
So far I don't see any workaround possible for you in Python, the only way would to first read the HyperFile and rewrite everything + the things that you want to Append (pretty inefficient).

I opened a bug report, to support APPEND within HyperFile.
I set this post to solved, and I added the tag ToFix t your topic, but don't worry we will keep you in touch when a fix will be available but we can't say when it will be available neither if it will be fixed.
Cheers,
Maxime.

Hi @reubenlara, I'm not able to reproduce here ID_BASEOBJECT_COLOR is correctly highlighted in R25.010 in Windows and Mac.

Would it be possible to share your full script with us? And also the complete error log.
However looking at the error the issue come later at the and this is the CallCommand(12298) which fail, moreover according to your screen you do have an object called 3D_Cursor so this branch will never be taken (at least not in your case).

Just to be sure would it be possible for you to write in the console c4d.ID_BASEOBJECT_COLOR and press enter. 908 should be written.

Thanks in advance,
Cheers,
Maxime.

Hi Camille one of the things that is a bit unclear to us, are you really using the cineware engine, or do you actually uses the sdk.zip provided in each Cinema 4D?
Cineware is an external dll that you can link to read/write c4d file without the need to install c4d. Since you mention that you want to create an exporter this is more suited for the usual sdk.

Would it be possible for you to share your actual code?

Thanks in advance,
Cheers,
Maxime.

Hi @camille-chigot, your question will be looked tomorrow morning in our daily SDK checks, however try again, it should work now, but we do have a file limit of 4096KiB (around 4.19mo) so if the file is larger either send us the file via mail at [email protected] or upload it within your preferred cloud hosting provider.

Cheers,
Maxime.

Hi Unfortually we do not provide support for 3rd party libraries. Even more Qt is not officially supported by Cinema 4D.

However it may be possible to make it work, so I would check first that the dll path Scipy try to load is valid, then that the dll is compiled with the same compiler used by Cinema 4D.

Cheers,
Maxime.

Hi Unfortually we can't help you since we are not bundle to Octane and they can do whatever (and even not exposing the version number). So your best luck will be to reach directly Otoy in their forum.

Cheers,
Maxime.

Hi @Артём, first of all welcome in the plugincafe community

You can use c4d.GenerateTexturePath to retrieve an absolute path from a relative URL.

You should also pass the document path, you can get it with BaseDocument.GetDocumentPath.

Cheers,
Maxime.

Hi again sorry for the long delay, pretty busy.

I looked at the noise code and it assume a cd->vd->tex to be defined unfortually allocating a dummy TexData is not working properly, I will need to reach development team to see if this is possible at all.

Cheers,
Maxime.

Hi he completely get out of my mind sorry, I will work on your topic in the upcoming days.
However I'm not sure if this is possible since you will probably need to instantiate some VolumeData which is not possible, but I will have a look.

Cheers,
Maxime.

Hi sorry for the late reply, I overlooked your topic.

You will need to override the Draw method of your ObjectData and then use BaseDraw.DrawTexture.

Cheers,
Maxime.

What is the version of your customer, this should be fixed until S24 version.

Yes it's an Okish solution, best way would be to create the context as demonstrate in urllib2.urlopen fails on C4D for Mac
