    RE: Sampling the falloff of a mograph effector? (python/R19)

    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.

    RE: 3rd party APIs into pyp/pypv file

    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.

    RE: Setting `coordinate system` using `MCOMMAND_MIRROR`

    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_TOLERANCE] = 0.01

        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

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

                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],

    RE: Get World Position of Obj A's position and Set it to Obj B's position

    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.

    RE: How to deepcopy DescID?

    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,

    RE: Python Script Gui: Use EditSlider Get Float

    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.

        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():

    RE: restore weight to BaseContainer and get it Vs Direct get weight from weight Tag

    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):

            pcount = op.GetPointCount()  
            jcount = tag.GetJointCount()
            self.jointdir = 0
     
            for m in xrange(jcount):

    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.

    RE: Adding items to a LONG/CYCLE description container.

    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.

    RE: Get all texture tags & show texture paths,but reflection channel throw error? :(

    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!
    Cheers,
    Maxime.

    RE: deformer object priority

    Hi @mike,
    No worries at all since, but please make sure to read and apply the rules defined on the following topics:

    • Q&A Functionality.

    Regarding your question, you can make use of the Shift Priority Tags. You can find more information on the priority in the c4d help.

    But C4D also offer the Shift Priority Tag.
    Finally, note in some case it can be a limitation of the viewport which not refresh properly while data are correctly set.
    And you need to manually refresh the viewport.

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

    RE: Running Automatic UV for all objects

    Hi @BineeMan sorry for the late reply I was pretty busy Friday and thanks @Dunhou for demonstrating how Packed Auto UV work.
    For Cubic and Angle you need to use c4d.modules.bodypaint.CallUVComman as demonstrated in the call_uv_command_ example.

    So for the Angle automatic UV you need to use the command ID c4d.UVCOMMAND_OPTIMALMAPPING with the next parameters:

    • c4d.OPTIMALMAPPING_PRESERVEORIENTATION # Preserve Orientation
    • c4d.OPTIMALMAPPING_STRETCHTOFIT # Stretch to Fit
    • c4d.OPTIMALMAPPING_DISTORTION # Maximu, Distortion
    • c4d.OPTIMALMAPPING_RELAXCOUNT # Relaxation Steps
    • c4d.OPTIMALMAPPING_SPACING # Spacing

    And for the Cubic automatic UV you need to use the command ID c4d.UVCOMMAND_OPTIMALCUBICMAPPING with the next parameters:

    • c4d.OPTIMALMAPPING_PRESERVEORIENTATION # Preserve Orientation
    • c4d.OPTIMALMAPPING_STRETCHTOFIT # Stretch to Fit
    • c4d.OPTIMALMAPPING_TWOD # 2D
    • c4d.OPTIMALMAPPING_AREAFAK # Maximum Area Factor
    • c4d.OPTIMALMAPPING_RELAXCOUNT # Relaxation Steps
    • c4d.OPTIMALMAPPING_SPACING # Spacing

    Cheers,
    Maxime.

    RE: Gradient Interpolation Error in 2024 release

    Hi @danielsian, I we need to update this example and also the documentation about Gradient. Thanks for bringing that to our attention.
    Gradient handling is now different and heavily rely on the maxon API via the GradientInterface. The old c4d.Gradient is now just a mirror of the GradientInterface.
    Therefor all constants were moved to the maxon API. Find bellow the adapted example:

    import c4d
    import maxon
    
    def main():
        # Create a new material and a new gradient shader.
        material = c4d.BaseMaterial(c4d.Mmaterial)
        shader = c4d.BaseShader(c4d.Xgradient)
        
        # Get a copy of the c4d.Gradient data referenced by the gradient shader
        # and a copy of the knot data stored in the c4d.Gradient data. The knot
        # data is expressed as a c4d.BaseCoontainer.
        gradient = shader[c4d.SLA_GRADIENT_GRADIENT]
        knotData = gradient.GetData(c4d.GRADIENT_KNOT)
        
        # Iterate over all knots in the knot data container and set their 
        # interpolations to linear. Each knot in the knot data container is itself 
        # a c4d.BaseContainer, storing the data for a single knot.
        for _, knot in knotData:
            knot[c4d.GRADIENTKNOT_INTERPOLATION] = maxon.GRADIENT_INTERPOLATION_TYPE.SMOOTHKNOT
    
        # Items can also be retrieved by their index from a BaseContainer, here 
        # the first index, i.e., second item, in the container. In this case the 
        # position of the knot is written and then the knot container is being 
        # written back into the index its has been retrieved from.
        knot = knotData.GetIndexData(1)
    
        knot[c4d.GRADIENTKNOT_POSITION] = 0.5
        knotData.SetIndexData(1, knot)
        
        # After these modifications the knots must be written back into the 
        # c4d.Gradient data, because GetData() returned a copy above. This also
        # does apply to the shader and its gradient for the same reason.
        gradient.SetData(c4d.GRADIENT_KNOT, knotData)
        shader[c4d.SLA_GRADIENT_GRADIENT] = gradient
        
        # Aside from assigning the shader to the correct parameter of the 
        # material, it is also important to call BaseList2D.InsertShader(), as 
        # otherwise the setup will not work.
        material.InsertShader(shader)
        material[c4d.MATERIAL_COLOR_SHADER] = shader
    
        # Finally, the material is being inserted into the active document and an
        # update event is being pushed event to Cinema 4D, so that its GUI can 
        # catch up to our changes. 'doc' is a predefined module attribute in 
        # script manger scripts which points to the active document. It is
        # equivalent to c4d.documents.GetActiveDocument().
        doc.InsertMaterial(material)
        c4d.EventAdd()
    
    if __name__=='__main__':
        main()
    

    For other values please take a look at the C++ documentation of GRADIENT_INTERPOLATION_TYPE.

    Cheers,
    Maxime.

    RE: C4d Connector problem in 2024

    Hi @filipst, I've published a new version of the Visual Studio Connector, it is available here and should be soon available via the VS Code marketplace.

    However while investigating the issue, I found out another one which was added very lately and is more critical since it prevent Cinema 4D to send data to the Vs Code extension. Sadly this will require a fix on Cinema 4D side. I'm trying to have this fix for Cinema 4D as soon as possible out.

    Cheers,

    RE: GetDefaultValue Not Working in C4D 2024

    Hi @Easan this function have been modified in C++ and we did not had the time to adapt it in Python. However rest assured this is in our top priority for the next release.

    With that said you can still retrieve the value using GetValue("value"). Find bellow and example, but first create a node material and select a port and run the example.

    import c4d
    import maxon
    
    
    def main():
        mat = doc.GetActiveMaterial()
        nodeMaterial = mat.GetNodeMaterialReference()
        nodespaceId = c4d.GetActiveNodeSpaceId()
        nimbusRef = mat.GetNimbusRef(nodespaceId)
        graph = nimbusRef.GetGraph()
       
        for port in maxon.GraphModelHelper.GetSelectedNodes(graph, maxon.NODE_KIND.PORT_MASK):
            print(port.GetValue("value"))
    
    
    if __name__ == "__main__":
        main()
    

    However this have some limitation since in some case when no value is available None will be returned. This is going to be fixed in the next version.
    Cheers,
    Maxime.

    RE: Converting ABC file to AEC using c4dpy?

    Hi unfortually the possible way is to render the scene.
    Within Cinema 4D you can call

    rd = doc.GetActiveRenderData()
    rd.Message(c4d.MSG_DESCRIPTION_COMMAND, {"id": c4d.RDATA_PROJECTFILESAVE})
    

    Which will simulate the click on the Save Project File... but this will open a File Selector dialog that you can't script.
    So the only way is to render the scene via c4d.documents.RenderDocument.

    Cheers,
    Maxime.
