It's much faster than 2014...not just in the rendering, but in the way it handles screen graphics and control updating...more responsive, I would say.  The library system has been completely revamped, and I like the new resizable thumbnails. As for the look...buttons and so forth...I can take or leave it and I wouldn't call it an improvement...it's just different. One thing that is nice is that the 4-view window system can be made asymmetric so you can have a larger preview window if you want.

Now the bad. I don't know it you use Poser with Vue, but they (once again) have bungled the Poser import. (after they'd just gotten everything straightened out in 2014) Lots of glitches. I haven't figured out most of them, but one is for certain: 2015 won't import figures with unimesh skinning. You know, 2014 had this same problem, but they fixed it. I don't know why they have to break things when they upgrade them...

I'd rather stay in my lane than lay in my stain!
