Thomas,

There is a specular size that controls the roughness value in the 
materials tab of PoseRay. PoseRay uses specular+roughness for 
highlights. In Poser this is controlled by the highlight size and in 
DAZ|Studio it is the glossiness in the advanced tab for each surface.

DAZ|Studio has a bug that results in exported scenes with full specular 
strength. Specular strength in DAZ|Studio is a multiplier of the 
highlight color. The only reason I see this parameter exists is for 
changing the amount of highlight without changing the RGB ratio of the 
highlight. Rather useless.

later,
