Hi @jenandesign, first of all, welcome in the plugincafe community.

No worry at all, since it's your first post, but I would like to point you about few rules in order to properly ask questions in this forum for future ones (I've set up this one).

• How to Post Questions (Especially the tagging system).
• Q&A New Functionality.

With that's said. Regarding your question. I get it to work (a bit hacky) but it's working.
When C4D render a scene, actually the whole scene is cloned in memory and then it renders this one. (It allow a user to still work on C4D while the other scene is rendering).
So this render scene is read-only, you shouldn't modify at anytime anything in this scene, or you can screw up the render.
Moreover in a shaderData, in order to optimize memory, only relevant information (aka polygon, UV) are copied. So you are losing your UserData.
This means you have to find another way to find your effector.
So the way I find to achieve what you want is to get the document from the object passed to the shader(the rendered document).
Then in this document, I search for an effector called "Plain" (Not the most robust way but it's working).

Then here the final code I put on the python color channel of a sketch and toon

import c4d

def main():
    doc = op.GetDocument()
    effector = doc.SearchObject("Plain")
    if not effector: return c4d.Vector()
    
    eff =  c4d.modules.mograph.C4D_Falloff()
    if not eff: return c4d.Vector()
    eff.InitFalloff(bc=effector.GetData())

    eff.SetMg(effector.GetMg())
    eff.SetMode(effector[c4d.FALLOFF_MODE])

     # World position currently sampled
    value = eff.Sample(wPnt, False)
    return c4d.Vector(value)

And the attached scene where a plain effector drives a mograph effector and the sketch and toon shader.
0_1542626486830_SketchAndToon.c4d

If you have any questions, please let me know!
Cheers,
Maxime!

Hi @merkvilson, I indeed overlooked the issue, since in all topic it's only Python 3.6, I didn't tried.

But in MacOs, certifi is not installed (which cause the issue), but you can directly get the certificate file to make it works as expected. Here the code which works on mac and windows.

import c4d
import os
import ssl
import urllib

f = os.path.join(os.path.dirname(c4d.storage.GeGetStartupApplication()), "resource", "ssl", "cacert.pem")
context = ssl.create_default_context(cafile=f)
urllib.urlopen("https://google.com",context=context)

Or with urllib2

import c4d
import urllib2
import os

f = os.path.join(os.path.dirname(c4d.storage.GeGetStartupApplication()), "resource", "ssl", "cacert.pem")
urllib2.urlopen("https://google.com", cafile=f)

Hi @merkvilson first of all pip and Niklas localimport module is completely two different things.

• pip is a python module manager (similar to package manager in unix). This means once it's installed to a python binary, it will be able to manage other modules, download them, install them with all their dependencies and update them and so on.
• localimport is a python module that let you manage import in a local way while in Cinema 4D by default is global. For more information please read how the import function works in python.
  Meaning if you add a module named xyz to the sys.path from your plugin A and from plugin B you try to import another module named xyz, it will load the one from plugin A (the first one register).

Now how to install pip?

1. Downloads https://bootstrap.pypa.io/get-pip.py.
2. Downloads the c4dpy version matching your Cinema 4D version. (Already included in R21)
3. Moves c4dpy and get-pip.py in the Cinema 4D folder.
4. Opens a shell to the Cinema 4D folder:
   • Window: Type cmd in the top path and press Enter.
   • Mac: Open a new shell, then with cd navigate to your Cinema 4D folder. (You can drag and drop the path).
5. Runs this command line c4dpy get-pip.py. This will execute the get-pip script which will, download and install the pip module.
6. Now you can start to play with pip c4dpy -m pip install numpy. c4dpy allow to runs any module with the -m argument see c4dpy commandline. in this case I asked to pip to download and install numpy but any other 3rd party compatible with pip can be downloaded and used.

With that's said we do not provide support for 3rd party modules, so if it does not work with Cinema 4D Python environment, we can't help you.

Cheers,
Maxime.

Hi @kisaf,

MCOMMAND_MIRROR is indeed a bit special because when you click on the Apply button from the GUI, it does send a message to some c4d elements, then these elements read MDATA_MIRROR_VALUE, MDATA_MIRROR_SYSTEM and MDATA_MIRROR_PLANE calculates values for MDATA_MIRROR_POINT and MDATA_MIRROR_VECTOR and then call the SendModelingCommand. Unfortunately, there is no way for you to send this message, and the best way to do it is to recalculate the stuff as bellow.

import c4d


def main():
    # Checks if selected object is valid
    if op is None:
        raise ValueError("op is none, please select one object.")

    # Defines some general settings, take care MDATA_MIRROR_VALUE, MDATA_MIRROR_SYSTEM and MDATA_MIRROR_PLANE
    settings = c4d.BaseContainer()
    settings[c4d.MDATA_MIRROR_DUPLICATE] = True
    settings[c4d.MDATA_MIRROR_SELECTIONS] = True
    settings[c4d.MDATA_MIRROR_ONPLANE] = True
    settings[c4d.MDATA_MIRROR_WELD] = True
    settings[c4d.MDATA_MIRROR_TOLERANCE] = 0.01

    # Corresponds to MDATA_MIRROR_VALUE, MDATA_MIRROR_SYSTEM and MDATA_MIRROR_PLANE
    value = 1000.0
    system = 0 # 0 = Object, 1 = World
    plane = 1 # 0 = XY, 1 = ZY, 2 = XZ

    if not 0 <= system < 2:
        raise ValueError("System can only be 0 or 1")

    # Buffer position vector
    pos = c4d.Vector()

    # Calculates Local (Object) coordinates
    if system == 0:
        globalMatrix = op.GetMg()
        if plane == 0:
            pos = globalMatrix.v3
        elif plane == 1:
            pos = globalMatrix.v1
        elif plane == 2:
            pos = globalMatrix.v2

        settings[c4d.MDATA_MIRROR_POINT] = globalMatrix.off + pos * value
        settings[c4d.MDATA_MIRROR_VECTOR] = pos

    # Calculates World coordinates
    elif system == 1:
        if plane == 0:
            pos = c4d.Vector(0.0, 0.0, 1.0)
        elif plane == 1:
            pos = c4d.Vector(1.0, 0.0, 0.0)
        elif plane == 2:
            pos = c4d.Vector(0.0, 1.0, 0.0)

        settings[c4d.MDATA_MIRROR_POINT] = pos * value
        settings[c4d.MDATA_MIRROR_VECTOR] = pos

    # Send the Modeling Operation
    res = c4d.utils.SendModelingCommand(c4d.MCOMMAND_MIRROR,
                                        [op],
                                        c4d.MODELINGCOMMANDMODE_ALL,
                                        settings,
                                        doc)

    c4d.EventAdd()


if __name__ == "__main__":
    main()

Hope it solves your issue, if you have any question, please let me know.
Cheers,
Maxime.

So regarding your script why it crashes, it's simply because you make an infinite loop with this code since you add each time something more to iterate.

for idx in newPos:
    newPos.append(GlobalToLocal(oldObject, idx))

Just to make it cleaner I've called objA and objB.
Then the needed steps are:

1. Get World Position from points of objB.
2. Convert these World Position in the local space of objA.

So as you may be already aware regarding our Matrix Fundamentals where is how to achieve both operations.

• Local Position to World Position corresponds to the obj global matrix where the position is locals to multiplied by the local position.
• World Position to Local Position corresponds to the inverse obj global matrix where the position will be locals multiplied by the world position.

Finally, before providing with the solution I would like to remind you to please always execute your code in the main function. The main reason is that if you transform your script as a button in the Dialog, every code that is in the global scope of your script is executed for each redraw of the Cinema 4D GUI (which is pretty intensive!). Moreover please always check for objects, if they exist or not try to adopt a defensive programming style in order to avoid any issues.

import c4d

def main():
    # Declares object variables
    ObjA = doc.SearchObject("A")
    ObjB = doc.SearchObject("B")

    # Checks if objects are found
    if ObjA is None or ObjB is None:
        raise ValueError("Can't found a and b object")

    # Checks if they are polygon object
    if not isinstance(ObjA, c4d.PolygonObject) or not isinstance(ObjB, c4d.PolygonObject):
        raise TypeError("Objects are not PolygonObject")

    # Checks Point count is the same for both obj
    allPtsObjA = ObjA.GetAllPoints()
    allPtsObjB = ObjB.GetAllPoints()
    if len(allPtsObjA) != len(allPtsObjB):
        raise ValueError("Object does not get the same pount count")

    # Retrieves all points of B in World Position, by multipling each local position of ObjB.GetAllPoints() by ObjB.GetMg()
    allPtsObjBWorld = [pt * ObjB.GetMg() for pt in allPtsObjB]

    # Retrieves All points of B from World to Local Position of ObjA, by multipling each world position of ObjB by the inverse objA.GetMg()
    allPtsObjANewLocal = [pt * ~ObjA.GetMg() for pt in allPtsObjBWorld]
    
    # Sets New points position
    ObjA.SetAllPoints(allPtsObjANewLocal)
    ObjA.Message(c4d.MSG_UPDATE)
    
    # Updates Cinema 4D
    c4d.EventAdd()

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

If you have any questions, please let me know.
Cheers,
Maxime.

Hi @mikeudin, due to how our Classic Python API is built deepcopy does not work since our python objects only store pointer to our internal C++ object and not directly to other Python objects, so deepcopy fail in this regards since, the deepcopy operation, free and try to recreate these data, which is not possible since they are not PyObject but real C++ object but copy.copy does works, but since it's a shallow copy operation it only works for one level (e.g. a dict of dict of DescID will fail).

For more information about the difference please read Shallow vs Deep Copying of Python Objects.

However here a couple methods to copy a dict.

import copy
dict1 = {'1':dId_one,'2':dId_two}
dict2 =  copy.copy(dict1)

dict1 = {'1':dId_one,'2':dId_two}
dict2 =  dict1.copy()

dict1 = {'1':dId_one,'2':dId_two}
dict2 =  dict(dict1)

Cheers,
Maxime.

Hi @mike, first of all I would like to remind you to read and use the Q&A functionnality.

Regarding your question, here is an example of a basic GeDialog, which make use to SetFloat to define a range.

import c4d

class MonDlg( c4d.gui.GeDialog):
    idSlider = 1000
    idButton = 1001

    # Create the Layout
    def CreateLayout(self):
        self.AddEditSlider(self.idSlider, c4d.BFH_SCALE|c4d.BFV_SCALE, initw=100, inith=20)
        self.AddButton(self.idButton, c4d.BFH_SCALE|c4d.BFV_SCALE, initw=100, inith=20,name = 'Get Value')	
        return True

    # Called after CreateLayout
    def InitValues(self):
        self.SetFloat(self.idSlider, 0.25, min=0.0, max=1.0, step=0.01, min2=0.0, max2=0.0)
        return True

    # Called for each interaction from a widget
    def Command(self, id, msg):
        if id == self.idButton:
            print self.GetFloat(self.idSlider)
        
        return True

def main():
    dlg = MonDlg()
    dlg.Open(c4d.DLG_TYPE_MODAL)

if __name__=='__main__':
    main()

If you have any questions please let me know.
Cheers,
Maxime!

Hi @chuanzhen actually the problem interested me and I took some personal time on my weekend to do some tests.

I did 2 test scenes, which was a cube with 163970 points driven by 3 joints
With your original source code 0.53 fps
optimize python: 1.09 fps (x2.05)
C++: 19.36 fps (x36.52)

And the other one was the same cube but driven by 11 joints.
With your original source code 0.37 fps
optimize python: 0.64 fps (x1.73)
C++: 12.08 (x32.65)

So here is the optimized python code. As you can see I try to avoid as much as possible doing operation in the nested loop.

class newskin(plugins.ObjectData):
 
    lasttagdirty = None   #for weight change update
    jointdir = None       #for joint change update
    cachedir = None       #for other bindmesh check
 
    def CheckDirty(self, op, doc):
        #check first run
        if op[c4d.NEWSKINTAG] is None:
            op.SetDirty(c4d.DIRTYFLAGS_DATA)
            return
 
        #check weight change
        if op[c4d.NEWSKINTAG].GetDirty(c4d.DIRTYFLAGS_DATA) != self.lasttagdirty:
            op.SetDirty(c4d.DIRTYFLAGS_DATA)
            return
 
        #check matrix change
        checktime = op[c4d.NEWSKINTAG].GetJointCount()
        cdirty = 0
 
        for i in xrange(checktime):
            cdirty += op[c4d.NEWSKINTAG].GetJoint(i).GetDirty(c4d.DIRTYFLAGS_MATRIX)
 
        if cdirty != self.jointdir or self.cachedir != op[c4d.NEWSKINCHECK].GetDirty(c4d.DIRTYFLAGS_CACHE):
            op.SetDirty(c4d.DIRTYFLAGS_DATA)
            return
 
        return
 
   
    def ModifyObject(self, mod, doc, op, op_mg, mod_mg, lod, flags, thread):
 
        if mod[c4d.NEWSKINTAG] is None or mod[c4d.NEWSKINCHECK] is None:
            return True
 
        tag = mod[c4d.NEWSKINTAG]
        self.lasttagdirty = tag.GetDirty(c4d.DIRTYFLAGS_DATA)  #get current weight tag dirty
        self.cachedir = mod[c4d.NEWSKINCHECK].GetDirty(c4d.DIRTYFLAGS_CACHE)    #get bindmesh check
        plist = [pos * op_mg for pos in op.GetAllPoints()]
        pcount = op.GetPointCount()  
        jcount = tag.GetJointCount()
        self.jointdir = 0
 
        for m in xrange(jcount):
            joint = tag.GetJoint(m)
            self.jointdir += joint.GetDirty(c4d.DIRTYFLAGS_MATRIX)   #all joint current matrix dirtycount
 
        temp = c4d.Vector()
        for n in xrange(pcount):    #n:point index  
            temp %= temp
 
            for m in xrange(jcount):
                joint = tag.GetJoint(m)
                weight = tag.GetWeight(m, n)
 
                if not weight :
                    continue  
 
                cjmg = joint.GetMg()
                jdict = tag.GetJointRestState(m)
                jmg = jdict["m_bMg"]
                jmi = jdict["m_bMi"]
 
                temp += weight * cjmg * jmi * plist[n]  #defrmer global pos
            plist[n] = temp
       
        plist = [~op_mg * pos for pos in plist]
        op.SetAllPoints(plist)
        op.Message(c4d.MSG_UPDATE)
 
        return True

And here the C++ version (compatible R20 only). It uses paralellFor, not sure it's really worth didn't do proper profiling about it but I wanted to try them. Moreover please do not consider my C++ code has fully optimized since you could probably improve it depending on the situation.

Hi @FlavioDiniz, first of all, welcome in the plugincafe community!

Don't worry, since it's your first topic, I've set up your topic correctly. But please for your next topics, use the Q&A functionnaly, make sure to also read How to Post Questions.

With that's said you can find the manual about SetDParameter in the C++ docs which will be trigger each time a user changes a value in the description of your tag. And also the C++ manual about GetDDescription.
Here a quick example of the implementation in python

    extensions = ["exr","hdr","jpg","png"]

    # Called by C4D when loading description
    def GetDDescription(self, node, description, flags):
        data = node.GetDataInstance()
        if data is None:
            return False

        # Load the description
        if not description.LoadDescription(node.GetType()):
            return False

        # If there is no description for c4d.TESTSCALE, we create it. Otherwise we override it and set DESC_CYCLE with our extensions list.
        singleID = description.GetSingleDescID()
        paramID = c4d.DescID(c4d.TESTSCALE)
        if singleID is None or paramID.IsPartOf(singleID)[0]:
            bcParam = description.GetParameterI(c4d.TESTSCALE)

            items = c4d.BaseContainer()
            for i, extension in enumerate(self.extensions):
                items.SetString(i, extension)

            bcParam[c4d.DESC_CYCLE] = items

        return (True, flags | c4d.DESCFLAGS_DESC_LOADED)

    # Called when a parameter is Set
    def SetDParameter(self, node, id, t_data, flags):
        if not node:
            return

        # called when the filename is changed. We add the path to our list and we return c4d.DESCFLAGS_PARAM_SET to inform c4d the paramaters is just sets
        if id[0].id == c4d.STRINGTEST:
            self.extensions.append(t_data)
            return (True, flags | c4d.DESCFLAGS_PARAM_SET)

        return False

If you have any questions, please let me know!
Cheers,
Maxime.

Hi @Ashton_FCS_PluginDev, we are glad to see you back in the new plugincafe community!
No worries at all since it's your first post here, but please make sure to read and apply the rules defined on the following topics:

• How to Post Questions.
• Q&A Functionality.

Regarding your issue, you read m_spec, but you never check if there is a bitmashader in it or not. And in your case, there is no, so m_spec is set to None, and you are then trying to access value.
So please always check for None.
Then since you directly read the BITMAPSHADER_FILENAME parameter from this shader, please also consider to check the shader type you retrieve, maybe a user used a noise and not a bitmap.

m_spec = userMat[c4d.MATERIAL_REFLECTION_SHADER]
if not m_spec or m_spec.CheckType(c4d.Xbitmap):
    continue

Finally, as you may already be aware, reflection gets multiple layers. You get some information in this thread, how to deal with it.

If you have any others question, please let me know!

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,

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.

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.

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.

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.

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.

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

As long as you do not insert it into the current scene, this is all fine

This will not cause memory leak since Python handle it efficiently, if you do not insert the object, the ownership of the PolygonObject will still be the Python object itself. Meaning when the variable will be deleted automatically by the Python Garbage Collector, the PolygonObject will also be deleted.

You could also make an empty PolygonObject like so c4d.PolygonObject(0, 0).

Maxime.
