  Halos.... ? (Message 1 to 5 of 5)

I'm not posting a file with this, I'd just like some help, since
this is a Tutorials group.  I've posted my first semi-gratifying image
on the binaries.images group, so if you want to take a look at it, it's
there....
    Anywho, my question is....  could someone explain to me a little but
more about halos?  I have MoRay, and I've looked through the POV docs,
and I'm never getting the results I'm after.  In my image, I have two
cones, a spotlight focused on each.  I'd like to get a dust-like effect,
or something of that sort, coming from the spotlight, so that it looks
sort of like a streetlight shining on the cones... or like sunshine
coming in from a dusty window... that sort of effect.  Is there anyway I
can do this? I'm trying what I 'know' how to do, but, obviously, that
isn't much.  What's the easiest way to do this?

Many thanks for your help,

~Dana

(Oh, what the heck, Ill post my file here, too!)

Have you read section 4.10.4 The Atmosphere in the docs?
Atmosphere is pretty slow to render and so a bit of a pain to get right
but the examples in the docs can be pasted straight into your scene as a
starting point.

Cheers, PoD.
