Applying material to Pattern

I have a part that has a patterned feature. I am trying to apply the same photoworks material properties to the pattern. There is a box in the editor that i select for propogate visual properties. This does not seem to apply to photoworks materials as when i render it, only the seed geometry gets the materials applied to it.
When i do a mirror, the photoworks materials will apply to seed and propogated geometry, but not if it is a linear pattern.
Any thoughts?
