After testing that out i can say too that this thing seems to be useless,
a tried all types of media, with filter and transmit and other
things.
By the Way i found an other thing which seems to be incorrect :
i understand it that way, when you use mediainteraction off on a
light_source
the light should interact in no way with the media, but it interacts with
the
absorption value, i mean the light gets dismished, when travelling thru
the media even if media interaction s off. should that be in that way ?
