Hello,
   
  I have 2 problems selecting faces. I currently have this:
   
               IINode node = iface.GetINodeByHandle(handle);
             if (node == null)
                 return;
   
             iface.SelectNode(node, true);
   
             iface.CommandPanelTaskMode = TASK_MODE_MODIFY; //2
             IObject baseObjectRef = node.ObjectRef.FindBaseObject();
             
             if (baseObjectRef.SubObjectLevel != 4)
                 baseObjectRef.ActivateSubobjSel(4, m_Global.XFormModes.Create());
   
             ITriObject triObj = (ITriObject)node.EvalWorldState(0, true).Obj.ConvertToType(0, m_Global.TriObjectClassID);
             var mesh = triObj.Mesh;
   
             MasterNode tempMasterNode = m_MasterNodeList[handle];
   
             IBitArray selectionArray = GetFacesBitArrayByID(treeNode.matID, tempMasterNode);
             if (selectionArray != null)
                 mesh.FaceSel = selectionArray;
   
  
  1st problem: ActivateSubobjSel method crashes Max when there are modifier on my node. Is there a way to go to the baseObject? Ignoring all the modifiers on top?
  2nd problem: This code is working with EditableMesh object but doesn’t work very well with EditablePoly. I can change the ITriObject to IPolyObject so it works on EditablePoly but then it doesn’t work on EditableMesh. I was wondering though if it’s possible to make it work on these 2 base meshes without checking the baseObject first.
   
  Thanks in advance,
Vin
