Quote - I am under the impression that V4 and the older generation have a fine topology but a questionable rigging.

I don't have the advantage of weight mapping available to me, so I have to agree. Antonia more than holds her own compared to commercial figures, for me; in fact if I know I'll require a challenging pose in a scene, then Antonia is my go-to gal.

I don't feel the lack of polygons either. I used to use V3 RR most of the time, and wish there was an equivalent reduced resolution V4 etc.

Maybe in an open source project such as this, there's more time and effort available to spend on refining the rigging and other aspects that might otherwise be subject to commercial restraints.
