Gregory's Server@lumiworx Do you attribute the software engineers that created Blender, Maya, or Zbrush in the creation of your work? Or are those simply tools you used to actualize your vision? Granted, a truly hardcore 3d artist could create an image using plotted points and a .CSV file, but that seems a pretty harsh hurdle to get over to "own" a particular work.
@gumwars The 3D model would be mine, as would the render created to present it.
Even though I'm not required or asked to... Yes, I do attribute the software when I present a render, commercial or FOSS.
However, if I were to publicly show a painting or a drawing or a film print, no, I don't credit the paint's or camera's maker, nor do I feel their branded technical expertise in their products is relevant. They are simple non-thinking tools.
