That's my point. You're balancing processor time vs. requirements in making a movie, since it's a factor now - render farms be damned. I'm not sure you have a point. The resolution makes no difference after a certain point; people who work in print have known this for years. Anything beyond about 450dpi is just gilding the lily because the eye simply cannot make the distinction between that and anything finer. The same would hold, IMHO, in texture maps: after a certain point, even for the best closeup, the amount of texture wrapped around a mesh becomes moot. There is no difference between a 3,000 pixel head map and a 12,000 in terms of the final result. So again, the resolution thing is just a canard: the amount of processing time is a non-factor if the base materials themselves make no difference.
