Some further explanation on how presets work:
The presets usually set a number of object-specific settings, such as
stick_color.
In the case of the ball & stick preset, stick_color is set to white for
the selected objects, and the radius is set to 0.14. To change that,
you'll need to change the setting for those objects:
# load some object
fragment arg, my_object
# call the present function
preset.ball_and_stick("my_object")
# to query
get stick_color, my_object
get stick_radius, my_object
# to set
set stick_color, grey, my_object
set stick_radius, 0.2, my_object
# to restore the object to using the global defaults
unset stick_color, my_object
unset stick_radius, my_object
Cheers,
Warren
