"In classic skin its all good so I suppose its better to switch back to classic skin when using PML (can you switch back and forth without loosing data?)"

That's what I'm afraid of.

If I have to switch to "Unimesh" skinning, what will that do to my cr2's ?

Will it mess with the other tools I regularly use to modify my figures ?

If I have to constantly switch back whenever I use PML, (Which I do use very, very often), will that "degrade" my figure over time ?

It took 13 years to develop that group of figures. I definitely won't give it up or start new just because Poser decides they aren't good enough anymore.

But I'm still hopeful this can be fixed one way or the other.
