Just a post to congratulate Andrew and the team!
My brother is an Interior Architect and I have been going on at him about the virtues of providing his clients with realtime walk through's using Virtual Reality and Augmented Reality. (I launched a new company in June called Augmented Reality Design Solutions).
I got him to send me an fbx of a retail interior / exhibition stand that he had designed so that I could create an Augmented Reality table top version.
Anybody who has worked with an Architect or Interior Designers files may know that they don't care about UV's because they don't usually have too.
I was left with a complex model with vertex colours assigned and loads (loads and loads) of sub objects to UV map in one sheet so I could create an efficient light map and ambient occlusion.
Every single other program I used choked to death when I tried to unwrap everything to one sheet. Blenders lightmap pack couldn't handle it. Zbrush unwrapped then died when I used the morph UV's button to see the results.
3D coat did what I needed quickly and gave me good, solid results.
