I was looking through the Marketplace, and saw something that I rather liked, but from the product shots it was painfully clear that the thing I hate most in a model was present: the hard 90 degree edge.

When you're making any kind of furniture - nearly anything actually-- you should never have a true 90 edge. They don't occur in nature, and the Poser render engine in particular renders them very harshly.

Its also trivially easy to bevel an edge, and given that that we're speaking of scenes which routinely carry tens if not hundreds of thousands of polys, spending a few on an edge which will render decently is not a big deal.

When I look at bad renders, the #1 problem is terrible lighting (and anyone can have nice realistic lighting with two clicks under Poser 7, if they trouble themselves), and the #2 problem is "razor-edge" geometry-- that's much harder for the user to fix.
