I'll have to look into that. It's gonna be a bit tricky since this is part of an
animation so the camera moves around.

I've never had much luck with normals. That's why the columns in the back have an
actual rough surface instead of a "normal" based surface.

If it started:
#macro ScalarRange(Seed)
  (rand(Seed)-rand(Seed))
#end

#macro VectorRange(Seed)
  (<rand(Seed),rand(Seed),rand(Seed)>-<rand(Seed),rand(Seed),rand(Seed)>)
#end

then it was John's makerock.inc. It's still up on the net at

Funny!

/That/ is the rock.inc version.

Makerock.inc does not have macros (at least in my version).

Or a world which lost most of its atmosphere down to almost Mars-like 
pressure levels, now too thin to maintain higher animal life forms and 
thus leading to the demise of its civilization (the ruins in the 
background), but still facilitating the growth of some hardy 
vegetation... a planet like Bitan in my projected Shams system!

See you in Khyberspace!
