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!

the DescID calculates as follows:


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

Hi Andreas,

I will definately look into this!
Thanks for your help and time!

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();  
// 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!

Could somebody please help me with this?
I've tried around 100 id's, but none of them work.

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);  
  LONG didValue = GvCall(od, GetMainID)(morphNode, GV_PORT_OUTPUT, id);  
  GvPort *port = morphNode->AddPort(GV_PORT_OUTPUT, didValue, GV_PORT_FLAG_IS_VISIBLE, TRUE);  
  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!

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!!
