Fine, but you did not tell me how to do it cos my sample above is not modifying
existing object but creating 3 new instances of it so I have all of them in the
place at once (basically what I am trying to achieve is obtain objects
coordinates to know where it remains - gradient polygon simulating base plane -
and then do some mathematics including camera position having my object facing
the camera at the same distance and angle every time I render something
independently from what camera position and angle are)...so? Please, can you
tell me the trick? :)
