        this is my first post.

    i have seen this topic posted before, but the solution doesn't apply to my sitation.

    i have an xpresso setup with a COFFEE node. the goal is to do an animated matrix extrude in r8.2 -- which, to some degree, i have accomplished. still, the results are only visible in the realtime editor display and do not show up in any rendered output.

    i also have a txt file of the COFFEE code for the r9.6 demo of c4d:

    var oldSteps;

    main()
    {
    println("oldSteps= ", oldSteps);

    var doc = GetActiveDocument();
    var op = doc->FindObject("MyObject"); // GetActiveObject(doc);
    var ver = GetC4DVersion();
    println("ver = ", ver);

    if (!doc->FindObject("Backup"))
    {

    println("'Backup' found? ", doc->FindObject("Backup")?"TRUE":"FALSE");

    var currentObject = doc->FindObject("MyObject"); // GetActiveObject(doc);

    println((currentObject == op)?"TRUE":"FALSE");

    var clone;
    clone = currentObject->GetClone(CL_NO_HIERARCHY);
    clone->SetName("Backup");

    GetActiveDocument()->InsertObject(clone, NULL, NULL);

    doc->SetActiveObject(currentObject);

    EventAdd();
    }

    // ***********************************************************************

    if (Steps != oldSteps)
    {

    var BaseDoc = GetActiveDocument();
         var currentObject = BaseDoc->FindObject("MyObject"); // GetActiveObject(BaseDoc);

    // reset object
         if (Steps != oldSteps)
         {
        
            currentObject->Remove();
            currentObject = BaseDoc->FindObject("Backup");

    var clone;
            clone = currentObject->GetClone(CL_NO_HIERARCHY);
            clone->SetName("MyObject");

    GetActiveDocument()->InsertObject(clone, NULL, NULL);

    currentObject = BaseDoc->FindObject("MyObject");
            BaseDoc->SetActiveObject(currentObject);
            EventAdd();
         }

    if (Steps > 0)
         {
         var bc = currentObject->GetContainer(); // "new" method found 2006-10-02 vs. old "new(BaseContainer)" method

    bc->SetData(MDATA_MATRIXEXTRUDE_STEPS, Steps);                                         
         bc->SetData(MDATA_MATRIXEXTRUDE_MOVE,   vector(0.0,0.0,50.0));
         bc->SetData(MDATA_MATRIXEXTRUDE_SCALE, vector(0.8,0.8,0.8));
         bc->SetData(MDATA_MATRIXEXTRUDE_ROTATE, vector((10.0/360.0)*(3.14),0.0,0.0)); // convert to RADIANS!

    bc->SetData(MDATA_MATRIXEXTRUDE_POLYGONCOORDS, TRUE);
         bc->SetData(MDATA_MATRIXEXTRUDE_VARIANCE, 0);

    var myres = SendModelingCommand(ID_MODELING_MATRIX_EXTRUDE_TOOL, NULL, currentObject, bc, MODIFY_POLYGONSELECTION); // ID_MODELING_MATRIX_EXTRUDE_TOOL

    if (!myres)
        {
          println("poss error. SMC returned false ", myres);
         
        } else println("***SMC called***");
        currentObject->Message(MSG_UPDATE);
        }

    currentObject = BaseDoc->FindObject("Null Object");
    BaseDoc->SetActiveObject(currentObject);
    }

    oldSteps = Steps;
    }

    i do not have r9.6, but i figured it would be easier for everybody to test and comment on.
    to create the scene file:

    • create a null object
    • put an Xpresso tag on it
    • put a User Data integer slider (1..8)on it
    • create a cube, make editable, rename it to "MyObject"
    • drag the NULL into the Xpresso, create an output port for the User Data slider
    • create a COFFEE node with an Integer input port named "Steps"
    • connect the nodes
    • code for the COFFEE node is above

    is there a faster way of posting a file???
    thanks for your help.

    I am afraid you can't do it this way. You can't add geometry during rendering. You can do this only with a Object plugin and the C++ SDK.

    Thank you for the fast and accurate reply.

    The C++ SDK is powerful, but also something I'm not quite ready for. Thank you for providing a direction to study.

    Is there any other method suggested for doing something like this in COFFEE?

    The one I'm considering is to do a sweeps nurbs using a spline created from the selected polygon edges. This may not work for the same reason given, but if I create the geometry beforehand, then maybe I will be able to animated the growth of the sweeps nurbs object(s). What do you think?

    Lastly, can geometry be subtracted or deleted during rendering? Or is there a way to copy just the geometry from one object to another without adding it? Am I being too litteral with the term "add geometry" and hoping to find a trick that doesn't exist?

    Thanks again.
