Okay, I think I got it figured. This is a straight import from Poser to Vue. Although the material assigned to the hair sparkles was the same as the ball and tail sparkles, they (the hair sparkles) had a color assigned. (Yet they still rendered grey.) The ball and tail sparkles were grey in the material editor. So, to get the hair sparkles to render in color, all I had to do was adjust the Ambient and Luminous sliders in the material editor. To get the ball and tail sparkles, I had to assign a color to the three materials then adjust the Ambient and Luminous sliders. This is the result--rendered with shadows off to avoid confusion. NOTE: In Poser, the only object that had a texture was the hair. The sparkles had only a transmap and ambient colors assigned. Strange.
