Thanks @m_adam Works as expected. Have a great day ahead!

Hello, Polygonize() is just using SendModelingCommand() with MCOMMAND_CURRENTSTATETOOBJECT. You can actually see the C++ source in c4d_basedocument.cpp in the cinema.framework. But I don't think that this commands merges all objects into one polygon object. best wishes, Sebastian

I create a workaround that is working. I think, like you say, that the Subdivision Surface is not ok, when I initially load the scene. I now get the polygon object under the sss and that works.

Read() and Write() works. Thanks.

Thanks, buddy! But the problem is that the most current one is not a way to go. If the user installed the plugin for R16, then the installer should open R16 itself. I'm trying to find and open it by the name, but the name is always different. It can be Cinema 4D / Cinema 4D R16 / Cinema 4D R16 Demo / Cinema 4D Demo / etc. Well. This is considerably easier on windows since I can check if it exists by using os.path.exists() function, but I have no Idea how to do this on Mac.

@m_adam Thank you for another detailed answer !

hello, To answer this question if someone want to do it by code. import c4d from c4d import gui # Welcome to the world of Python # Main function def main(): #get the selected object op = doc.GetActiveObject() if not op: raise TypeError("there's no object selected") if not op.IsInstanceOf(c4d.Opolygon): raise TypeError("obj should be a polygon object") #setup neighbor nbr = c4d.utils.Neighbor() nbr.Init(op) #get the selected edge bs = op.GetSelectedEdges(nbr,c4d.EDGESELECTIONTYPE_SELECTION) #maximum number of edge should be number of polygon * 4 sel = bs.GetAll(op.GetPolygonCount() * 4) #get all polygon vadr = op.GetAllPolygons() #init point a and b index to -1 for error check a = b = -1 #initialise a counter to check in sel array. countEdge = 0 #we can check now every edge to find the corresponding points. So for each polygon for i in xrange(op.GetPolygonCount()): #get the polygon information pli = nbr.GetPolyInfo(i) for side in xrange(4): # Test all 4 sides of a polygon # Only proceed if edge is marked # and edge really exists (for triangles side 2 from c..d does not exist as c==d) if pli["mark"][side] or (side==2 and vadr[i].c == vadr[i].d): continue #if the edge is marked as selected in our sel array if sel[countEdge]: if side==0: a=vadr[i].a; b=vadr[i].b elif side==1: a=vadr[i].b; b=vadr[i].c elif side==2: a=vadr[i].c; b=vadr[i].d elif side==3: a=vadr[i].d; b=vadr[i].a countEdge +=1 if a == -1 or b == -1: raise ValueError("points index can't be negatives") #get all points array points = op.GetAllPoints() #Get the direction of the edge in global coordinate (multiply the points'vector by the matrix of the object) opmg = op.GetMg() #i've picked a direction from point a to point b so the angle could need to be reverted. dirVector = points[b]*opmg - points[a]*opmg #normalize a vector is often a good idea. dirVector.Normalize() #transform the vector to hpb note the result is in radian hpb = c4d.utils.VectorToHPB(dirVector) #transform radian to degree hpb.x = c4d.utils.RadToDeg(hpb.x) hpb.y = c4d.utils.RadToDeg(hpb.y) hpb.z = c4d.utils.RadToDeg(hpb.z) print "the edge is poiting to",dirVector,"the corresponding angle is", hpb # Execute main() if __name__=='__main__': main() Cheers Manuel

hello, if you don't have anything else to add, i'll mark this topic as "solved" Cheers Manuel

Hi Maxime, thank you very much! Good to know. I would otherwise searched forever. Cheers, PdZ

Ok, I will give it a try and let you know. Thanks.

Just to add some side notes : SendModelingCommand is waiting for a list of objects in case you want to execute that command on several objects. In your case, you only got one element in your list. You can have more informations about list here

Hello, there's no real list where you can find easily those IDs. @m_adam came with this idea : open the Script log (menu script > script log) and click the button you want to call. in the console you will see something like c4d.CallButton(tool(), c4d.MDATA_NEWTRANSFORM) so you know that the ID is c4d.MDATA_NEWTRANSFORM Another place to look for, is the folder ressource/modules where you can find the files .res that build the ui. (using your OS search function will help a lot) Openning those file you will find the information BUTTON MDATA_NEWTRANSFORM { FIT_H; } and you can maybe open the file with the same name with the extention .h where you will find the id MDATA_NEWTRANSFORM = 701, // Button Other than that, there are the enums on the documentation like this page but it's not really "user friendly" Let me know. Cheers Manuel

Don't feel sorry yes this is the issue and since Knot ID are not ordered from right to left but from creation order its why it's confused you. Moreover, using a for loop will make way more sense and help you to avoid this kind of stuff. grad1 = shdr1[c4d.SLA_GRADIENT_GRADIENT] grad2 = shdr2[c4d.SLA_GRADIENT_GRADIENT] for knotId in xrange(grad1.GetKnotCount()): knot = grad1.GetKnot(knotId) grad2.InsertKnot(col=knot['col'], pos=knot['pos'],index=knot['index']) grad2.FlushKnots() shdr2[c4d.SLA_GRADIENT_GRADIENT] = grad2 Finally, a BaseShader is derived from BaseList2D which is derived from C4DAtom that mean you can use GetClone to retrieves a clone of this shader so your code can look like. import c4d def main(): mat = doc.GetFirstMaterial() colorShader = mat[c4d.MATERIAL_COLOR_SHADER] if colorShader is None: return copyColor = colorShader.GetClone() mat[c4d.MATERIAL_DIFFUSION_SHADER] = copyColor mat.InsertShader(copyColor) mat.Message(c4d.MSG_UPDATE) mat.Update(True, True) c4d.EventAdd() # Execute main() if __name__=='__main__': main() Cheers, Maxime.

@m_adam Thanks for further clarification specially the catch with the dialog's on the script. Will now closed the thread. Have a great day ahead!

@m_magalhaes said in Add/Remove Groups of User Data: Hello, I was also talking about something like this. But it's not the best way to go. I suggest a TagData (plugin) with his own UI. pyTagCode = '\ import c4d \n\ #Welcome to the world of Python \n\ \n\ def main():\n\ print "this ia a message"\n\ \n\ ' import c4d # Main function def main(): if op is None: gui.MessageDialog("Please selecte a target object") tag = c4d.BaseTag(c4d.Tpython) tag[c4d.TPYTHON_CODE] = pyTagCode op.InsertTag(tag) c4d.EventAdd() # Execute main() if __name__=='__main__': main() By the way, don't forget you can save tag presets, that include python tags. You can simple add them with right click on your object in OM and "Load tag preset" Cheers, Manuel Oh this is good to know! Thanks so much for the information, this is quite helpful! Matt

Thanks for the response @m_adam Have a great day ahead!

Thanks for the reply! I'll try that, though I thought that SCENEFILTER_IGNOREXREFS would keep xrefs from being loaded, and since my plugin edits the xref path/name, this would not work. But then again, perhaps I assumed wrong. I appreciate the help! By the way, the idea of classification by tags appears to be a good way to escape the messy folding out tree of classification system that we are all used to. I'll use it next time.

Hi panney, thanks for reaching out us. With regard to the issue you're experiencing, it's pretty likely that the cause is a different revision between the c4dpy executable and the Cinema 4D revision. Please be sure that they both matches (20.059 c4dpy is available here[URL-REMOVED]). Last but not least, here you can find more detail on the c4dpy executable. Best, R.

wow! i love that. great job!
