For *$&)'s sake, who cares if you didn't model that million polygon tree or that cute girlie model from scratch, poly by poly? The final image is all that matters. That's it. End of story. Finito. This purism in 3d is getting really tiresome. Nobody cares about the brushes or the paints that the old masters used, why should anybody care if you created everything from scratch yourself? Major studios regularly buy 3d models and textures from commercial sources. Do you care that Marlin textures were used in The Matrix Revolutions? I bet not. I'm sure it didn't stop you from enjoying the movie.
