I was trying this for a couple of days and I finaly fugured out how to do it.
I set reflect color up a little, the filter up a lot (like 190 or so).  And
finally the most important.  I found that you should not touch the shiny
slider.  It seams to negate anything with reflect and filter.
While we are talking about benchmarks.  I made an sphere object half red and 
half blue with the atributes as above.  It is sitting on a ground with the 
dots texture, and two light sources casting shadows.  I rendered it in
interlaced HAM. On a stock Amiga 2000 1 MEG.  It only took 23 hours and 58 min.
Fast huh :-)
