I'm trying to render one of my IRTC entries from last year, but I've hit a
problem: The original render was done using POV3.5 release candidate 2, and now
that I'm trying to render it with the final release of 3.5 the fog looks
different. The original effect was to have very tubulent fog, so that some
patches had almost no fog whilst others had quite a lot, but now I can't find
any setting that produces this much contrast.

So, has anything changed in the fog calculation since POV 3.5 RC 2?
If so, how can I make the scene look the same now?

Thanks in advance for any help.

Actually, it might be something to do with gamma...

In any case, it's something that has changed since RC 2.

Any ideas?

  Try adding this to the beginning of the scene:

global_settings { noise_generator 1 }

#macro M(A,N,D,L)plane{-z,-9pigment{mandel L*9translate N color_map{[0rgb x]
[1rgb 9]}scale<D,D*3D>*1e3}rotate y*A*8}#end M(-3<1.206434.28623>70,7)M(

It's a good idea, but it didn't work. The patterns in the fog altered but the
amount of contrast is still way too low.
