E-on has announced a Vue 2016 R5 patch. Be wary about simply applying it though, as they’ve made changes to the whole User Interface…
“Many UI/UX and navigation improvements, with homogenized navigation manipulation throughout the whole UI, and several dialog and editors redesigned.”
Erk! Nope. The only reason I can see to upgrade is that R5 apparently has a fix to import a Poser 11.2 scene more accurately (it seems some bit of the process broke in R4, re: Poser 11.2 against 11 or 11.1).
Update: Actually the UI is not too bad. It’s not a total makeover, more like a series of small tweaks.
