Glad to hear it is better.
Everyone who compares 3.0 with 3.5, watch out for assumed_gamma global
setting. Most scenes created for version 3.0 (Windows) used a value of 2.2,
whereas 1.0 is more likely today in version 3.5.
If there were a purely numerical conversion of atmosphere (and halo) to
media this could be more exacting. For example, atmosphere 'distance' can't
be replaced solely with just media 'density'. I don't believe so anyhow. It
would likely need a spherical pattern centered on the camera and have a
fall-off, like that of fog, encompassing the realm as necessary (distance +
100% saturation = sphere boundary). All conjecture though, until tried.
