The Gen3 figures were not made as morphs to be added to the basic V4 and M4 figures (as in the Gen4 figures). Each of the figures were different in significant ways. But, rigging and weight/bulge-mapping any one of these figures can provide a start to doing any of the other figures.

To get a figure that will take advantage of all the poser of P9/PP2012, requires that the figures be re-rigged from the ground up, then requires that weight-maps and bulge-maps be created without any conversion from the original joints. Unfortunately, the antiquated meshes cannot be altered or updated, because this would break all of the morphs.

As should be clear, these figures will then perform better in P9/PP2012, but will be inferior to figures that are made (mesh, rig, weight-maps, bulge-maps, UV-Maps, texture maps [including bump, displacement, and normal maps], morphs, poses, and content) to be fully Poser compliant and enabled.

The process of updating legacy figures is helping to create a new generation of Poser users with the skills needed to create the exceptional content that Poser and Poser users deserve. It is worth the effort, but the appreciation of the Poser community helps make the work worthwhile.
