   It *HAS* a very wide variation in grain colors, but the focal blur makes
it almost disappear... and if I make the grain bigger to avoid this, it
doesn't look like grains anymore. :(

   Me too, tried it before but never got it right... I think it's due to the
fact that I was always using a single while loop to place the pebbles, but
this time used 3 loops, with increasing random sizes and decreasing number
of pebbles. Also, the pebbles are not totally random in their placement, as
I used a pigment function (granite) to determine if a pebble should be
placed or not. And BTW, it is just a single mesh pebble made with
Wings3d... :)
