Installed it... despite indicating that I wanted it to, it did not preserve any preferences, so back to factory default with everything. Also, python scripts are not in the scripts menu although they are still in the correct folder. I'll either need to reinstall them or find a way to get Poser to recognise the scripts are there.

Polygon reduction worked a treat.

Grouping works as well, but be careful of any clothes that use trans maps. Any skin underneath the transparent areas get deleted or hidden! There is an option to manually select the areas to hide, but of course that's slower.

For me, despite having no lack of power on my system, it freaked out when I tried to render something. Screens flickering, even got an OS warning that the GPU wasn't coping (despite being near top end with current drivers). Set to separate process, works like before.

Essentially, 2 hours on I have ALMOST got back what PP2014 was already giving me. I think that the poly reduction capacity will be worth it eventually (like in a day or 2). For $40 I'm not complaining (much). It would have been nice if it had just kept the scripts and prefs in place...
