hi,
im trying to add some uvw data to an object in my scene using this code:

    
    
    
    
    CreateUVWTag(op)  
    {  
      var t_tag = new(UVWTag);  
        
        
      var a_uvwcoords = new(array,1000);  
      var counter;  
      var v_coord = vector(0);
    
    
    
    
      for(counter=0; counter < 1000; counter++)  
      {  
        v_coord.x = 1.0;  
        v_coord.y = 1.0;
    
    
    
    
        a_uvwcoords[counter] = v_coord;  
      }
    
    
    
    
      
     var vc = new(VariableChanged);  
     vc->Init(0,op->GetPolygonCount());   
     if (!t_tag->Message(MSG_POLYGONS_CHANGED,vc))  
       return;
    
    
    
    
     if(!t_tag->SetData(a_uvwcoords))  
     {  
      println("SetData Failed!");  
     return;  
     }  
       
      t_tag->Message(MSG_UPDATE);  
      if(!op->InsertTag(t_tag, NULL))  
      {  
       println("InsertTag Failed!");  
     return;  
      }  
        
       op->Message(MSG_UPDATE);  
    }

but it keeps saying SetData Failed! in console
Why is it doing this?

I fixed it, I have to create an array that has exactly 4 times the polygon count.
i.e

    
    
    
    
    var a_uvwcoords = new(array,op->GetPolygonCount()*4);
