[PyMOL] movie from chempy objets

[<but...@ya...>]

Greetings

I need to create pseudo-atoms with Van der Waals
radius defined by me, I know how to do it using
chempy, and loading the chempy objets into pymol, but
i need to create several chempy objets and show them
in pymol as frames of a movie. (i.e getting a movie of
an objetc which VdW radius changes in time) How can I
do this?  How can I make a movie from a serie of
chempy objects?
I would really appreciate if someone could help me
with this.
thanks in advanced, and sorry bout my english (Not a
natives speaker)
