After acquisition of Redshift, i hope we get node material system v.2 and sdk for it.

Aaron, i think it will be closed work in progress. I read about it from blog at maxon

Andreas thank you! You need new pool for fish

Welcome, Manuel! xplode them all !!!

Hello
Same here for python. Even check by AddPortIsOK(), says True, not adding

I also test c++ code, it adds to object operator(like topic master wants) but does not to nodemaster and no connect

{
    BaseDocument *doc = GetActiveDocument();

    BaseObject *obj = (BaseObject *) doc->GetActiveObject();
    if(!obj) return FALSE;

    XPressoTag *xTag = (XPressoTag*)obj->GetTag(Texpresso, 0);
    if(!xTag) return FALSE;

    GvNodeMaster *nm = xTag->GetNodeMaster(); 

    GvNode *n1 = nm->GetRoot();
    GvPort *p1;
    if (n1->AddPortIsOK(GV_PORT_OUTPUT,40000002))
    {
	    p1 = n1->AddPort(GV_PORT_OUTPUT, 40000002, GV_PORT_FLAG_IS_VISIBLE, TRUE);
	    print("True"); 
    }
    else
    {
	    print("False"); 
    }
      
    GvPort *p3 = n1->AddPort(GV_PORT_OUTPUT, 536870935, GV_PORT_FLAG_IS_VISIBLE, TRUE);
    
    GvNode *n2 = nm->CreateNode(nm->GetRoot(), ID_OPERATOR_OBJECT, NULL, 0, 0);
    GvPort *p2 = n2->AddPort(GV_PORT_OUTPUT, 40000002, GV_PORT_FLAG_IS_VISIBLE, TRUE);

    if (p1 && p2)
    {
        GvNode *n1u = NULL;
        GvNode *n2u = NULL;
        GvPort *p1u = NULL;
        GvPort *p2u = NULL;
        if (nm->IsConnectionValid(n1, p1, n2, p2, n1u, p1u, n2u, p2u))
        {
          n2->AddConnection(n1, p1, n2, p2);
        }
     }
    n1->Message(MSG_UPDATE);
    n2->Message(MSG_UPDATE);
    nm->Message(MSG_UPDATE);

    EventAdd();
}

@a_block and sdk team
Cool forum...!!!

Hello
I read manual, repeat with sdk (zip file), compile succesfully and start thinking about author of tool. I'm fan of Niklas Rosenstein and his craftr. New tool reminds me craftr.

Thanks a'lot for tool!
