V4 makes use of Poser 5/6 material settings and was designed to be used in Poser 6 (P5 will announce the error, ""This file has a newer version number than expected." when V4 is loaded). V4 uses alternate specular and alternate diffuse settings with math functions and edge blending.

V4 also uses dial grouping, but not in a very thorough fashion. Partial poses and injection morphs are in separate groupings.  Expression morphs aren't broken out the way EFrontier figures are where eye, nose, and mouth morphs are grouped in separate sections.
