C8.5 is set to use the old CMS not the new CMS. The C8.5.? beta is specifically to update carrara to the new CMS {as the rest of the so called fixes are for features that aren't broke in C8.5}.

Personally I'd recommend dumping both, they are far more trouble then they are worth. Oh ya, that is right, DAZ did shuve CMS down our throats with C8.5 by making it mandatory to use autofit. So I use Studio to preset my characters which doesn't need CMS to use autofit.

So why is it mandatory for C8.5 users when autofit apparently functions in Studio with out CMS?
