Right - but if you created an object with transmit 1, then you wouldn't even see
it at all. So your background with "transmit 1" is invisible - so why even have
it?
Just delete / comment out those lines.
If background and sky_sphere can be overwritten with new values, it might be
useful to pop a little macro into a newbie include file that will be the last
line in the .pov file. Then background and sky_sphere can be overwritten with
clear textures a s a quick diagnostic / fix, and as a reminder to those who
haven't used it in a long time...
include "newuser.inc"
transparent_background ()
