Ill try and answer some of those none DPI questions to the best of my knowledge.

Crease Angle :

This is used when you have smoothing turned on under the figure/props settings.

the angle amount (default is 80) is the amount of degrees difference between 2 polygons before poser will render a sharp edge between two smoothed areas.

a good example in a corner of a wall. the angle is 90 degrees, so poser will create a "crease" at the corner o that the edge looks sharp, and not rounded.

what alot of people dont know is that if you turn off smoothing in the figure/object properties, poser will use the smoothing groups assigned by the model to decide what to smooth, and where to place creases. this is by far the most ideal choice in 90% of situations, as most modellers add smoothing groups as there modelling.

the smoothing option I am referring to is in no way similar to the smoothing option in the render settings window. which is actually a sub-devision option.

a handy thing to note. should you turn on mesh smoothing in the render settings window, it will smooth out curved surfaces BETWEEN creases. the actual crease itself is not sub-devided, which can make for some wierd looks!  also, too low a resolution models can have issues when this option is turned on because they look like they bulg or bloat, as the sub-deviding system tries to create a smooth curve with only a few polygons as a surface guide.

ok, got a little carried away there.

Minimum Displacement Bounds:

as far as I can remember, this setting simply tells the rendere to ignore displacement mapping that is less that the number specified. this is handy in scenes that you need to have displacement mapping running, but the scene is creating a heavy load already. at a setting of .01 any displacement that is 0.01 and below will be ignored. this also means that if you plug a bump map into the displacement channel, and set it to 0.02 displacement, the actualy rendered displacement will be from 0.02 down to 0.0. Poser would ignore any part of the bump map that drops the displacement to below 0.01.

hope this helps/makes sense
