Just came across this in MEP 2016 Premium 15.0.0.107 (UDP3) but don't have time until later today to research it properly.
Is it just some basic misunderstanding of mine (perhaps I haven't yet installed a Xara plugin or something) or has the entire editing functionality been removed?
EDIT: I did have time to check a few basics:
1. Ran MEP 2014 Premium on this PC. That has same issue.
2. Dusted off my previous PC and ran MEP 2014 Premium. That does not have the problem. As soon as I choose a 3D title (or double click an existing one) I get a 'MAGIX 3D Editor' window with all editing tools.
So it seems that the built-in Xara 3D add-on or plugin or whatever it's called is integrated with MEP 2014 - but only on my old PC. How can that be? And in what version or patch did this change occur?
It's not a major issue for me. I clearly don't use 3D tiltles much or I'd have noticed this months - or years? - earlier. But as a matter of principle I never like to lose features! 🙂
