[away3d] fog filter

[desgraci]

looks like the first post dine entered, so apologize if double post,
the question is, how to make the "fog bubble" caused by the fogfilter
to move with the camera "a la green planet", cause right now, the idea
was to dont render all the poly that r too distant, but i cant get it
to move, no attributes in fog, neither using onenterframe updating,
also i found that the colormaterial of the fogfilter doesnt use the
alpha attribute, im wrong?
