You're welcome, Manuel.

Actually, I usually prepare all the textures and mapping to be in UVW mapping, when texturing is required.
But, mainly, what I need is exporting geometry that is animated.

Thank you very much, Manuel.
I will send the scene to the e-mail you provided.

I'm trying to export a Dynamics MoGraph animation, with a Voronoi Fracture object.
If I export as OBJ, it works fine.
If I export as C4D, all the saved files are the same, and have no animation.

I have a script that exports a sequence of OBJ files out of an animated Cinema 4D scene. It works perfectly.
I would like to be able to do the same, but export as a sequence of C4D files.
What I need is to export a sequence of frames (the scene has animation, of course), in C4D format, but with everything polygonized.
I'm using:

...
            doc.SetTime(curr_time)
            # Force the redraw of the document
            doc.ExecutePasses(None, True, True, True, c4d.BUILDFLAGS_NONE)
            c4d.EventAdd(c4d.EVENT_FORCEREDRAW)
            c4d.DrawViews(c4d.DRAWFLAGS_FORCEFULLREDRAW)

            bufferedNumber = str(frame_num)
            frame_num=frame_num+1

            # Export the C4D file
            file_name = os.path.join(file_path,obj_name+bufferedNumber+".c4d")

            poly_doc=doc.Polygonize(keepanimation = False)

            if poly_doc != None: c4d.documents.SaveDocument(poly_doc,file_name,c4d.SAVEDOCUMENTFLAGS_DONTADDTORECENTLIST | c4d.SAVEDOCUMENTFLAGS_SAVECACHES,c4d.FORMAT_C4DEXPORT)

But all the saved files are the same and I wanted each file to export as different frame, already polygonized.
Is this possible?

Once again, thank you, Manuel.
I had to do a few changes and it is working now.
I even made it select the faces that are within a certain angle from the camera.
Here is my code:

            for i,poly in enumerate(faces):
                a,b,c,d = poly.a,poly.b,poly.c,poly.d
                pta = points[a]*mg
                ptb = points[b]*mg
                ptc = points[c]*mg
                ptd = points[d]*mg
    
                v1 = pta-ptb
                v2 = ptb-ptc
    
                normal = v1.Cross(v2)
                normal.Normalize()
    
                if c != d:
                    center = c4d.Vector((pta.x+ptb.x+ptc.x+ptd.x)/4.0,(pta.y+ptb.y+ptc.y+ptd.y)/4.0,(pta.z+ptb.z+ptc.z+ptd.z)/4.0)
                else:
                    center = c4d.Vector((pta.x+ptb.x+ptc.x)/3.0,(pta.y+ptb.y+ptc.y)/3.0,(pta.z+ptb.z+ptc.z)/3.0)
    
                direction = cam_off - center
                norm_dir = direction.GetNormalized()
                angle = NINETY - normal.Dot(norm_dir)
    
                if (angle > 0.0 and angle < max_ang):
                    selection.Select(i)

Thank you Manuel.
Your code is for an object, not a face.
So, I tried to adapt it and this is what I got (and it doesn't really work):

def main():
    selected=doc.GetActiveObjects(c4d.GETACTIVEOBJECTFLAGS_0)

    if selected==[]: return
    
    bd = doc.GetActiveBaseDraw()
    cam = bd.GetSceneCamera(doc)
    if cam == None: cam = bd.GetEditorCamera()
    cam_mg = cam.GetMg() # in case I need it
    cam_off = cam_mg.off # in case I need it

    for op in selected:
        if op.GetType() != 5100: continue
        mg = op.GetMg()
        faces = op.GetAllPolygons()
        points = op.GetAllPoints()
        
        selection = op.GetPolygonS()
        selection.DeselectAll()
        
        for i,poly in enumerate(faces):
            a,b,c,d = poly.a,poly.b,poly.c,poly.d
            pta = points[a]
            ptb = points[b]
            ptc = points[c]
            ptd = points[d]
            
            v1 = pta-ptb
            v2 = ptb-ptc
            
            normal = v1.Cross(v2)
            normal.Normalize()
            normal = normal * mg
            
            if c != d:
                center = c4d.Vector((pta.x+ptb.x+ptc.x+ptd.x)/4.0,(pta.y+ptb.y+ptc.y+ptd.y)/4.0,(pta.z+ptb.z+ptc.z+ptd.z)/4.0)
            else:
                center = c4d.Vector((pta.x+ptb.x+ptc.x)/3.0,(pta.y+ptb.y+ptc.y)/3.0,(pta.z+ptb.z+ptc.z)/3.0)
    
            center = center * mg
            
            is_vis = bd.BackfaceCulling(normal, center)
            
            if (is_vis == True):
                selection.Select(i)
                
    c4d.EventAdd()

What could be wrong?

How can I determine if a polygon on a polygonal object is facing the current (user or editor) camera?
I know there is a BackfaceCulling function but it always returns me with True.

Great, I will do that. :-)

Since it is my serial protection code, I may have to edit things a bit, to protect my secrets ;-)
I will see if I can adjust to code to provide as much information as possible, without revealing too much, as soon as I get home.

I still get the same error, even after adding the #include "maxon/string.h"
I also replaced the DiagnosticOutput() with ApplicationOutput(), but the error persists.

Actually, yes.
Would it be better to use GePrint?
Or was it discontinued?
What is the best way to print to the Console now, in C++?

I'm getting this error message:

Undefined symbols for architecture x86_64:
"ToString(String const&, maxon::FormatStatement const*, bool)", referenced from:
void maxon::ToStrHlp<String>(maxon::String&, String const*, maxon::FormatStatement const*) in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

And I'm not even using the ToString in any of my code.
Trying to recompile all my plugins to R21 is being really hard :-(

I set the stylecheck.level to zero and the complains about the indentation disappeared.
I also tried that type of structure but the error still appeared, when the stylecheck.level was set to 3.
Now I'm getting different types of errors.

I'm getting lots and lots of errors complaining about wrong indentation.
Damn!!! It almost looks like I'm programming with python, instead of C++ :-(

I have this snippet of code:

    for (f = 0; f < 32; f++)
    {
        ch = user_id.GetPart(0, 1);
        
        if (ch != "-")
        { the_id = the_id + ch; }
    }

And it keeps telling me that there is a "wrong indentation of if", no matter how I indent the "if" statement.
How can I possibly indent the "if" statement to make Xcode stop telling me that the "if" is badly indented?
Damn, these new limitations of composition are very strict!!!

Thank you very much.
It seems to work :-)

This is for C++.

I have a String variable containing alphanumerical characters.
How can I get the ASCII value of each character?
For example, if my String variable is "a1b2", how can I get the ASCII values of each character (97,49,98,50)?

And, if I have an Int32 variable containing a numerical value, how can I create a String out of that ASCII value.
For example, if my Int32 variable has a value of 102, how can I create a String that contains "f" ?

I have been going through the documentation but these simple conversions, that are so basic in other languages, are not simple to understand in the C++ documentation.

Thank you very much, RIccardo.
I will look into it tonight when I get home.

I'm trying to get my plugins up and running with the new serialisation scheme of R21.
But, when I type this:

maxon::String prodID,sysID,userID,licenseID, userName;
GetGeneralLicensingInformation(prodID, sysID, userID, licenseID, userName) iferr_return;

I get an error in the "iferr_return;" and the error is: Use of undeclared identifier 'tmperr_ies'
What could be going wrong?
I'm on Mac OS 10.15.1, Xcode 11.2.1

I tried to compile the SDK plugins in R21 and I got this error:

error: Build input file cannot be found: '/Applications/Maxon Cinema 4D R21/sdk/frameworks/core.framework/generated/hxx/register.cpp' (in target 'core.framework' from project 'core.framework')

The "register.cpp" file exists. So, why is it producing this error?
