: no_shadow feature without the pass_through feature).  Comments?

  I think that a compromise could be the perfect solution:

  By default, applying no_shadow to an object also applies pass_through
to it.
  If you don't want photons passing through, you can specify it like this:

object
{ MyObject
  no_shadow
  photons { pass_through off }
}
