Well, if render times are the only issue, you might want to play with this:

I could have sworn that there used to be some macro called "FastCloud" 
floating around. In fact, I remember it filling up my search results to 
the point that I had to hunt to find anything else. Now I can't find it 
at all. Am I going nuts?

One major known problem with supporting V-class is the complexity of its 
PCI bus adapter (EPIC and SAGA). Support for the V-class isn't going to 
happen until some really masochistic person who has access to a V-class 
is, uh, challenged by this.

No. Not nuts. There is the FastClouds macro by Zeger Knaepen which I use 
very often and gives really excellent results. I know Zeger posted the code 
some time in the past but I am unable to find that post again.

Oh yes, a tiny little bank office, so small that two customers barely 
can squeeze themselves in front of the automatic counters...

...you surely meant "bench", didn't you?

See you in Khyberspace!

yes, I should put it on my website actually :)
but for now: see attachment.  And here's a demo-scene:

--BEGIN CODE--
#include "fastclouds.inc"
fastclouds(<750,600,-500>*1000,.455,.1,0,10,.05,0,<1.5,1.3,1.1>,1)
fog {
  fog_type 2
  distance 75
  color rgb <213,205,194>/255 //<.6,.7,1>
  transmit 0
  fog_offset -1
  fog_alt 2
}

sky_sphere {
 pigment {
  planar
  color_map {
   [0 rgb <22,44,68>/255]
   [.5 rgb <88,120,179>/255]
   [1 rgb <213,205,194>/255]
  }
 }
}

--END CODE--

These are the macro-arguments:
1. Sun Location
2. cloud 'Cast' (0=no clouds, 1=fully clouded sky, can be >1)
3. 'Fluffyness', controls the sharpness (or lack thereof) of the clouds
4. Translate-vector for the cloud-pattern
5. Size of the cloud-skysphere (*500)
6. Size of the cloud-pattern
7. Minimum transparency, or: the main-transparency of the clouds (could be 
seen as the cloud-thickness)
8. Color of the Sun
9. Color of the clouds

also, you can provide your own cloud-pattern by #declare'ing CloudForm 
(which should be a pigment)

cu!

Thanks.

Good idea:  I had downloaded the ivy generator before on my old computer, but
not yet on my new one.  I'll be sure to add some ivy next time I render.

    I had a good play with IG last night, first time for a year I guess, and 
I'm trying to capture a good scene with the ivy trailing down a giant wine 
glass. Hmm, so far, so good. I might post this one.

    But do continue with your image, I feel it will be worth it in some way.

  You could simply use a plane with the image of the clouds.

  The advantage of this is that if you ever need to re-render (because
eg. you improved the scene), you won't need to post-process again.

He-he! "bank" is bench in my language as well, I suppose it is in most
Germanic languages. ;o)
