Thank you for the help.
        
        I have gone thru the example there.
        I'm doing a similar thing as in the example.

        The program does
        not complain of any kind of error, etc. It just
        does not draw the newly loaded tiles.

        One thing to note here is,
        I'm using the same function to load tiles initially
        into the scene graph. That works fine. Updating the
        deleted nodes creates problem somehow. Do you ( / anyone )
        have an idea as to what could possibly be wrong?
        
        Thank you,
        Deepti
