I am currently working on a scene featuring some kind of a futuristic subway
tunnel. I want to have concrete slabs that make up the floor (and the
walls?) of the tunnel (where the rails are...later on). Can anyone suggest a
realistic way to model these (objects and textures ), and possibly some
cracks in the concrete and between the slabs? Also, any good way to make a
nice-looking riveted metal plate without a bump_map (it's cheating, really)?
You know, the kind you see on sci-fi movies, with many pieces riveted
together. Lastly, any idea what the cross-section of a subway rail looks
like? Here in Sofia we've had subway for about a year now but I've never
used it nor seen it...

Thanks in advance.

  Here are a couple of textures I use for concrete. Use them if you wish.

 #declare Concrete =
   texture { pigment { granite turbulence 1.5 color_map {
    [0  .25 color White color Gray75] [.25  .5 color White color Gray75]
    [.5 .75 color White color Gray75] [.75 1.1 color White color Gray75]}}
    finish { ambient 0.2 diffuse 0.3 crand 0.03 reflection 0 } normal {
    dents .5 scale .5 }}

   #declare Concrete1 =
   texture { pigment { granite turbulence 1.5 color_map {
    [0  .25 color White color Gray95] [.25  .5 color White color White]
    [.5 .75 color White color White] [.75 1.1 color White color Gray85]}}
    finish { ambient 0.2 diffuse 0.3 crand 0.003 reflection 0 } normal {
    dents .5 scale .5 }}

Thanks!
BTW, are these from the 1000+ textures you once mentioned in the newsgroup
(regarding a texture utility, as far as I remember) ?
