Any suggestions on how to make the fog look a bit better?


Thanks,

Not sure what "better" would be here.  You could add turbulence to this ground
fog though to get a clumpier one, something like a dry ice mist.  But the
light and shadow boundaries will not show up in it as does with 'media' no
matter what.  If you don't know already, using a filter or transmit in the fog
color will affect objects having filtered and/or transmitted pigments (even if
hollow).

// stirred up ground fog
fog {
  fog_type   2
  distance   10
  color      <.9,.9,.9>
  fog_offset 0.1 // initial height
  fog_alt    1.0 // height drop off
  turbulence 1.0 // higher more (seems scaled smaller too)
  turb_depth 1.0 // higher sharper
  octaves    1   // lower smoother [0,1,2,3...N]
  omega      1.0 // higher sparser or tighter
  lambda     1.0 // higher clumpier
  up <0,1,0>
}

maybe dont use fog, instead try some planes with a very transparent cloud
texture - the same technique thats used in games - or a combination of that
and a normal fog

More turbulence in the Fog seems a good idea, I would also suggest
something structured in the background, at least some sky/wall.

IMO dense fog often decreases depth of an image, probably mainly due to
the missing shadows.

Create objects in the background, fog makes more sense if
background elements are progressively hidden and "eaten"
by the fog.

Also, investigate into multiple layers (different colors,
depth and height) of ground fog.

I think it would look really nice with some visible light beams.
