Want to recommend UVLayout, it’s a great time savior!
Old school UI, but beast at what it doing.
Also Zbrush is really cool for quick mesh prototyping(Especially when you have modeling background and you know what to avoid, how many polygons you want to have and so on)
Ah, yea… I’ve got Articy: Draft as well. I was hoping for something a bit more… I dunno. I was thinking about designing my own Game Design Document template-style thing using VB and SQLite
