you are right..... I can't find a way to effectively pull them off as of yet like this:
as of now they are these things scattered along a spline and those other things are scattered along each roof plane with 5 seperate material id's with brightness set to -10 -5 0 5 10 for variation

anyways, i'm sipping on a cold beer now in hopes of a eureka! moment.....
(i'm also thinking about this in terms of workflow and mass production..... not just a one off roof model that I can spend days or weeks modeling...)
