Just because a model has been subdivided doesn;t mean it will look better. great examples some people have pointed out are VERY high poly models that don;t bend as well, or look as good as lower poly counterparts.

An excellent example that comes to mind, is the daz martian war machine. if you still have the original around, load it up and render it.

Then load up the improved rigging and optimised mesh version I did for daz, and render that.

The original model have almost 100,000 polys, and the optimised one had less then 26,000 if I recall.

Yet both look identical rendered.

Sub d is great gaming tech, for VERY low poly models to make them look better, but once you get past a certain poly count level, you don;t seem much (if any) improvement at all.

Also, if you do subdivide a model, bear in mind all the morphs are lost.

Way too many people take way too many things way too seriously.
