V4 with her 77.000 polygons is one of the highest polygon figures available for Poser.

Do the following:

a) Use Snarly's scenefixer to set the crease angle on all groups to 180°. If you do not have scenefixer, you will have to do it manually in each of the groups parameters.

b) Always render with Smoothing enabled in the render settings.

c) If you have Poser Pro of a later version set SubD to level1.

Setting crease angle to 180° and rendering with Smooth polygons enabled in the render settings will expand your figure slightly Setting SubD to level 1 will shrink the figure slightly. They even out each other.
