Thanks for the hint, that was easy enough for me ;-)
Thorsten,
the hardcoded value of 1000.0m is now settable at runtime with
/sim/rendering/minimum-sky-visibility
and defaults to 1000m, so the default behaviour is unchanged.
For the precipitation effect, I'm currently working on exposing most of
the effect's properties to the property tree and implementing the
current "magic" using property rules with a disable-switch.
That way you get access to particle speed, -size, -color and many more.
I somehow expect that one day you might want to correctly model the size
and color of the snowflakes ;-)
Torsten
