do you have the 3D Max example?
right now from what you posted I find the higher reflection model more
persuasive.
I am not sure if you follow these groups but the blurred
reflection/brushed metal reflection/partial reflection problem has a
long history. Attempts to get a "universal solution" by trying to
model the effect in a literal way, such as Jaime Vives Piqueres'
solution, yield pretty good results for a subset of situations. I also
just read where Rune has a solution for brushed copper. It was mentioned
by Phil Brewer, the winner of the Music round in his txt file:
http://www.irtc.org/ftp/pub/stills/2006-04-30/cacoph.txt
There have been many other contributions to solve the problem.
In my own experience I find that adjusting the finish, sometimes in
extreme ways, in conjuction with the lighting gets close. Recently I was
struggling with the problem for a chalice I was rendering and found that
the background to reflect issue, mentioned in this thread also, had a
huge effect.
Have you fully explored the possibilities of the finish {} and
reflection {} statements, including fresnel with ior and so on?
