Does anyone know why VSS would cause my figures in Textured display mode to "white-out" ???

What I mean by "white-out" is that after applying VSS (Vss3) my figures displays totally white - like with 100% white ambient, totally flat lighting. I'm using Poser Pro 7.0.4 (latest patch).

This even persists to a intermittent degree if I switch to simple smooth shaded mode.

I feel like this has been asked before, but I could find anything in this monster thread (oh how I wish you could search within a thread!!!)

Thanks!!
