    Hi,

    I'm working on an objectData plugin with some morph tags and XPresso files.
    In one XPresso file I need to access the strength of a pose of the morph tag.
    For that, I need the DescID of the strength of that specific pose.
    How should I go on this?

    Now I have an operator_object node where I drop my morphTag onto with OperatorSetData (DROP_IN_BODY)
    After this I'm not sure on what to do.
    I somehow need to get the right DescID to use in GvCall.
    I've tried this, but it's not working:

      
    DescID myMorphDescID = DescID(DescLevel(myFirstMorph->GetID()), DescLevel(MORPHTAG_STRENGTH));  
    

    How should I correctly retrieve the right DescID?
    Thanks in advance for your help and time!

    Hi,

    the DescID calculates as follows:

    morph->GetID() * ID_CA_POSE_ANIMATE_CNT + ID_CA_POSE_ANIMATE_OFFSET + ID_CA_POSE_ANIMATE_STRENGTH
    

    By the way, this thread may be also interesting in this context.

    Hi Andreas,

    I will definately look into this!

    Hi,

    I can't get it to work. The result for my DescID(1101) should be correct, but if I put that in GvCall, it seems to do nothing.
    Here is my code for the morph xpresso node:

      
    GvNode* morphNode = nodeMaster->CreateNode(nodeMaster->GetRoot(), ID_OPERATOR_OBJECT, nullptr, 350, 0);  
    if (!morphNode) return false;  
    morphNode->OperatorSetData(GV_ATOM, morphTag, GV_OP_DROP_IN_BODY);  
    GvOperatorData* morphData = morphNode->GetOperatorData();  
    DescID morphDescID = firstMorph->GetID() * ID_CA_POSE_ANIMATE_CNT + ID_CA_POSE_ANIMATE_OFFSET + ID_CA_POSE_ANIMATE_STRENGTH;  
    // Untill here everything works perfectly fine, and the DescID I get has the value 1101  
    Int32 morphInID = GvCall(morphData, GetMainID) (morphNode, GV_PORT_INPUT, morphDescID);  
    GvPort* morphInPort = morphNode->AddPort(GV_PORT_INPUT, morphInID);  
    if (!morphInPort) return false;  
    

    Thanks in advance for your help and time!

    I've tried around 100 id's, but none of them work.

    Hi,

    I'm still using a temporary internet connection. So I can't reply back to you about this.
    But I do have some code for handling PoseMorphs and Xpresso that might possibly help you out.

    This is R13 code:

    //This is an example of loading a PoseMorph tag into a node in the xpresso editor  
    //Then adding the first morph's strength output port in the xpresso node  
      
      
    //PoseMorph tag required headers  
    #include "..\..\..\resource\modules\ca\res\description	caposemorph.h"  
    #include "..\..\..\..\resource\_api\c4d_libs\lib_ca.h"  
      
    //GvCall required headers  
    #include "c4d_graphview.h"  
    #include "c4d_operatorplugin.h"  
    //A custom macro for getting the node's data  
    #define GvCall(op,fnc) (((GvOperatorData* )op)->*((OPERATORPLUGIN* )C4DOS.Bl->RetrieveTableX((NodeData* )op,1))->fnc)  
      
      
    Bool SimplePlugin::Execute(BaseDocument *doc)  
    {      
      PolygonObject *obj = (PolygonObject * ) doc->GetActiveObject();  
      if(!obj) return FALSE;  
      
      //Get the xpresso and PoseMorph tags on the object   
      XPressoTag *xTag = (XPressoTag* )obj->GetTag(Texpresso, 0);  
      if(!xTag) return FALSE;  
      CAPoseMorphTag *morphTag=(CAPoseMorphTag* )obj->GetTag(Tposemorph);  
      if(!morphTag) return FALSE;  
      
      //Get the xpresso's master container  
      GvNodeMaster *nm = xTag->GetNodeMaster();   
      
      //Create a new Object type node  
      GvNode *morphNode = nm->CreateNode(nm->GetRoot(), ID_OPERATOR_OBJECT, NULL, 120, 200);  
      
      //Assign the new node to the morph tag  
      //This acts like dragging an dropping the morph tag onto the xpresso Object node  
      morphNode->OperatorSetData(GV_ATOM, morphTag, GV_OP_DROP_IN_BODY);  
       
      //Get the morphNode's data  
      GvOperatorData *od = morphNode->GetOperatorData();   
      
      //Get the first morph's strength description and use it to create an output port for it   
      CAMorph *firstMorph = morphTag->GetMorph(1);  
      DescID id = DescID(ID_CA_POSE_ANIMATE_DATA, firstMorph->GetID()*ID_CA_POSE_ANIMATE_CNT+ID_CA_POSE_ANIMATE_OFFSET+ID_CA_POSE_ANIMATE_STRENGTH);  
      LONG didValue = GvCall(od, GetMainID)(morphNode, GV_PORT_OUTPUT, id);  
      GvPort *port = morphNode->AddPort(GV_PORT_OUTPUT, didValue, GV_PORT_FLAG_IS_VISIBLE, TRUE);  
      
      nm->Message(MSG_UPDATE);  
      
      EventAdd();  
      return true;  
    }

    Hi Scott,

    Thanks for your answer!
    I have more or less the same code.
    I did some testing with GePrint and found where the problem is.

      
    Int32 morphInID = GvCall(morphData, GetMainID)   (morphNode, GV_PORT_INPUT, morphDescID);  
    

    This line does not store the inport ID :s
    I have no problem with setting the morphData, morphNode or morphDescID, only the morphInID.

    Does somebody know what could be the problem here?
    Maybe a moderator?

    Thanks in advance for your help and time!

    Hi,

    first things first:
    Scott, I'm glad to see you again. Hope your life is getting better again.

    Now, for the question:
    Casimir, did you see how Scott generates the DescID in his code? Did you change your code accordingly?

    Hi Andreas,

    Well, I thought I did, but apparentally I was not paying quite the right attention.
    Therefor, I'm really sorry!

    If I change it to Scott's way it works perfectly.

    Thanks for your answers, both Scott and Andreas!!
