3D is always going to beat 2D for volume, yes.By sheer volume, probably whoever made an official D&D sculpture.
I don't think we count every single copy of a piece of art that got printed/cast as a separate entry, but if we did the top slot would almost certainly be one of the sculptors who worked on the D&D Miniatures prepaint figs. They were made in huge numbers, enough so that "millions' might not even be an exaggeration for some of the commons - and most sculptors did more than one fig for the game.Do we count whomever designed the sculpt for the 4e bugbear? Because AFAICT there are millions of those.
But I doubt that's the intent of this thread or there'd be a strong bias toward people who contributed to core books rather than supplements.
Hard to say who produced the greatest number of unique pieces of art over the years, but there's one thing I'm sure of: Having a single drawing carved up to make up the art on fifteen different Spellfire cards doesn't count each card toward your tally!
