Metalize! Shader Presets for DAZ Studio
I would be curious to see people's results with the "Metalize! Shader Presets for DAZ Studio" product at http://www.daz3d.com/pc-anniversary-sale-week-2/metalize-shader-presets-for-daz-studio .
Specifically, the various worn/tarnished/aged versions of the brass/bronze/copper type metals on a variety of shapes other than just the sphere and plane in the promo. I imagine lighting and other objects in the scene would affect the outcome a lot too.
