Hello,
I would like to create a gateway between C4D and a Web application by using the clipboard.
But in C4D, when I copy a mesh to the clipboard, it don't seems to be into the OS clipboard system (I don't see any data using a clipboard inspector like InsideClipboard). Can you confirm ?
@lev said in Plugins limitation count:
Hi guys, can u please solve the limitation of loading maximum 50 python plugins ? I dont understand whats the point of it and quite a bit annoying... A plugin pack basically kills every other plugins.... Thanks in advance
I can only agree.
Some times for one plugin you need to register multiple ObjectData or TagData, so it increase quickly...
Just for the info, calling the command to open the PictureViewer and RenderDocument with both c4d.RENDERFLAGS_CREATE_PICTUREVIEWER and c4d.RENDERFLAGS_OPEN_PICTUREVIEWER works just fine for me :
c4d.CallCommand(430000700) # Picture Viewer
c4d.documents.RenderDocument(doc, rdData, bmp, c4d.RENDERFLAGS_EXTERNAL | c4d.RENDERFLAGS_CREATE_PICTUREVIEWER | c4d.RENDERFLAGS_OPEN_PICTUREVIEWER)
Hello, it's indeed about Python plugins on S24 and R25 and OSX, and I guess other C4D version and OS.
It's a shame that it is limited to 50 ObjectData, 50 TagData, etc.., the common user will not check the console window and will think it's a bug from the plugin.
I hope it wil change one day. 
Thanks for your answer
Hello,
I have a customer that can't install a plugin, I check his console and I see the message :
OSError : cannot handle more than 50 object plugins.
As it's tagged with "OSError", I guess it depends of the OS, what can we do to increase this limitation ?
Hello,
I have a CommandData Python plugin that contains different options.
When I assign a shortcut to my CommandData, or add it to a custom layout, it opens with the default options.
Is is possible to define different shortcuts or custom layout icons that pass parameters to my CommandData plugin and then preset different options ?
For example, imagine a shortcut that execute the Optimize command with the Unused Points checked, and an other one unchecked.
Is it possible ?
Thanks,
Aah ok, I misunderstood indeed. Thanks a lot for your complete answer.
I take a look on all of this.
Mm, it did not work for me, the message was still not triggered even with a message ID higher than ID_TREEVIEW_FIRST_NEW_ID.
I managed in a different way with PluginMessage and c4d.GePluginMessage
But contrarely to what say doc, it's not the easiest way if you want to pass some data lol, the data received from PluginMessage is not an object but a PyCapsule object.
Here is how I retreived the original data object, it's not very elegant but it works :
import ctypes
import _ctypes
def getObjectFromCapsule(capsule):
ctypes.pythonapi.PyCapsule_GetPointer.restype = ctypes.c_void_p
ctypes.pythonapi.PyCapsule_GetPointer.argtypes = [ctypes.py_object, ctypes.c_char_p]
pointer = ctypes.pythonapi.PyCapsule_GetPointer(capsule, None)
return _ctypes.PyObj_FromPtr(pointer)
def PluginMessage(id, data):
if id == MY_UNIQUE_ID :
o = getObjectFromCapsule(data)
o['foo'] = 'bar'
return True
return False
And then in my other plugin :
o = {}
print(c4d.GePluginMessage(MY_UNIQUE_ID, o)) # {'foo': 'bar'}
Hello,
I try to send a message to a CommandData plugin like this :
class MyPlugin(plugins.CommandData):
def Message(self, type, data):
print("test", type, data)
return True
if __name__ == "__main__" :
plugins.RegisterCommandPlugin(id=1057321,
str="test",
info=0,
help="",
dat=MyPlugin(),
icon=None
)
And then send the message like this in the console :
c4d.plugins.FindPlugin(1057321).Message(123)
It returns True but nothing print. Do you know why ?
Hello,
The question was posted some years ago but I would like to know if with all the last updates there is now a possibility to add a falloff tab on a Python deformer plugin like in C++ ?
Thanks,
The informations a bit dispatched and I don't find the doc very clear, for example, there is no link to download Project Tool on the Project Tool page, and globally not enough examples in the sdk.
Sorry but the more clear doc to build and update faster our plugins is the tutorial made by a member here, because all the infos are on the same page : https://developers.maxon.net/forum/topic/10967/compiling-the-cinema-4d-r20-c-sdk-examples
Thanks for the info.
By the way, how can we disable the "Style guide" errors ?
For example, all my { after "if" generate an error "Style guide requires a new line for the substatement of if.".
Thanks for your help,
Before all these steps I extracted the sdk.zip into the Cinema 4D R20 folder.
What do you mean by "run the project tool on that "sdk"-folder" ?
I executed the command : kernel_app_64bit.exe g_updateproject="C:\Program Files\MAXON\Cinema 4D R20 Demo\plugins"
where "plugins" folder is from the sdk.zip.
I removed my plugin, to try to build the sdk, but when I open the plugins/project/plugins.sln, I got the exact same error about the file not found :
C:\Program Files\MAXON\Cinema 4D R20 Demo\plugins\microsdk\project\microsdk.vcxproj : error : Le projet importé "C:\Program Files\MAXON\Cinema 4D R20 Demo\frameworks\core.framework\project\core.framework.includes.props" est introuvable. Vérifiez que le chemin dans la déclaration <Import> est correct et que le fichier existe sur le disque. C:\Program Files\MAXON\Cinema 4D R20 Demo\plugins\microsdk\project\microsdk.vcxproj
Edit : My bad, I just needed to execute the tool to the frameworks too :
kernel_app_64bit.exe g_updateproject="C:\Program Files\MAXON\Cinema 4D R20 Demo\frameworks"
I understand now what you mean.
It works now.
Hello,
I tried to make a new plugin with the Project tool, but I got an error when I exec the vcxproj file generated. Here is my steps :
I find the documentation to start a new C++ project very messy, and I lost 10 min to understand that the old forum was down and to find the new one, because there is no link nowhere to it on the "How to get Plugin IDs" page. : /
