Eric, I apologize, a while back I thought you meant you were modeling objects with Universe, the Starfield program! Why didn't you set me straight? Good stuff, and a great question for Bryce-physics! Have you considered making the texture map of the logo into an actual object? This would let you use the Mask options in the Bryce renderer. I did this with some books a while back, for the gold-leaf cover effects on the bindings...
