Did you take a look at Johannes Hubert's image as mentioned in a
post a few threads up?

I had it downloaded to read off line and have apparantly read it
(as it's marked as read), but never remember seeing it.  I think
that he got some really good sharp results from using what
appeared to be a somewhat simplified method, but understand this
is something to do with the way media/atmosphere works
differently in 3.1.

So after reading you saying that you were giving up with this,
and siing you return to it with vigour, I'm sure we'll se some
spectacular images using this technique soon.

Cheers
