There are three kinds of sharpness to deal with - the sharpness of 3D geometry, the sharpness of shader/texture (procedural and image map) details, and the sharpness of reflected details.

Related is smoothness - of reflection blur, of focal blur, etc.

The key render setting parameter that affects all of these is Min Shading Rate.

The key setting for image maps is not a render setting - it's the Texture Filtering value on each node in the advanced material room.

Here are a couple threads that cover various topics. Note that older threads suggest that Texture Filtering should be off, always. We had no other option back then. Today, the best suggestion is Texture Filtering set to "Crisp". There are quite a few other "best practices" and the easiest way to apply them is to get SnarlyGribbly's "SceneFixer" Python script.

Again - In 2010 I said "I freely admit (and often am pained) by the fact that Poser's texture filtering is too aggressive. It would be great if it had a dial instead of just on or off." Well - now we have the Crisp setting which is the best.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
