Is there a particular setting and also area that you can show me so I can see these? On an initial quick look just loading your model and cranking up the slider towards the "more polygons" side, I get a result that does not seem to have anything like that visible, it looks like this:



Are you seeing something different than that or is there a specific area of the model where you're having a problem?

The best way to get more evently distributed facets is to use the "Divide larger than" setting in the expanded dialog. You can put in a distance value there and any polygon larger than that size will be further subdivided, that tends to help make a more uniform dicing up of polygons. For example here I've set Angle = 5 and "Divide larger than" = 1 unit:
