Hey while you're here do you know if it is safe to subdivide an object from within the GetVirtualObjects() method?

i place my object inside  a hypernurbs (Osds) to do so, but i think you mean something other. it should be able by using CommandData

here is a snippet of how i used the optimize command on a polygon object.

  
      if (op->GetType()==Opolygon)  
      {  
          ModelingCommandData cd;  
          cd.doc = doc;  
          cd.op = op;  
          BaseContainer bc;  
          bc.SetReal(MDATA_OPTIMIZE_TOLERANCE, tolerance);  
          bc.SetReal(MDATA_OPTIMIZE_POINTS, TRUE);  
          bc.SetReal(MDATA_OPTIMIZE_POLYGONS, TRUE);  
          bc.SetReal(MDATA_OPTIMIZE_UNUSEDPOINTS, TRUE);  
          cd.bc = &bc;  
          if(SendModelingCommand(MCOMMAND_OPTIMIZE, cd))  
          {  
              cd.op->Message(MSG_UPDATE, NULL);  
              BaseTag *phongTag = op->MakeTag(Tphong);  
              BaseContainer *bc = phongTag->GetDataInstance();  
              bc->SetBool(PHONGTAG_PHONG_ANGLELIMIT,TRUE);  
              bc->SetReal(PHONGTAG_PHONG_ANGLE,ToRad(winkel));  
          } else {  
               GePrint("failed");  
          }  
      }  

hope this makes sense

edit: in your case it'd be the MCOMMAND_SUBDIVIDE .. check the sdk for its parameters...

but for some reason it keeps crashiung on me when I try to do it.

MAX_ANGLE is equal to pi   and subAMount is a real that the user can adjust.

try catching the crash with

if(SendModelingCommand(MCOMMAND_SUBDIVIDE, mdat))
{
GePrint("done");
}
else
{
GePrint("failed");
}

just to be on the safe side..

Any thoughts?

another thing could be worth a try, to set the Parameters for an extra BaseContainer like i did it in my example:

BaseContainer bc;
          bc.SetReal(MDATA_OPTIMIZE_TOLERANCE, tolerance);
          bc.SetReal(MDATA_OPTIMIZE_POINTS, TRUE);
          bc.SetReal(MDATA_OPTIMIZE_POLYGONS, TRUE);
          bc.SetReal(MDATA_OPTIMIZE_UNUSEDPOINTS, TRUE);
          cd.bc = &bc;

and in the if (SendModelingCommand... call "cd.op->Message(MSG_UPDATE, NULL);"

Oh, wait, i didnt see you setting mcd2.op to your object, maybe thats the main problem

Awesome..  It works.   Used your different basecontainer suggestion.

//SUBDIVISION
		Real subAmount = bc->GetReal(SPACEROCK_SUBDIVISIONS);
  
		BaseContainer bc2;
		
		bc2.SetBool(MDATA_SUBDIVIDE_HYPER, TRUE);
		bc2.SetLong(MDATA_SUBDIVIDE_SUB, subAmount);
		bc2.SetReal(MDATA_SUBDIVIDE_ANGLE, pi);
  
		mcd2.bc = &bc2;
		mcd2.op = polyCube;
		mcd2.mode = MODIFY_ALL;
		mcd2.doc = hh->GetDocument();
		
  
		if(SendModelingCommand(MCOMMAND_SUBDIVIDE, mcd2))

			GePrint("done");

Thanks again.  I'm calling it a night.   Thanks for your help.

Hi, i did a quick test on subdividing and it works here.. dont ask me why it needs to create the dependency list twice, but if i dont do it, the plugin is updating everytime something changes in the editor even if you turn the camera and such.. if someone can tell my why, i'd be happy.

anyways, here is what is working for me:
