For anyone used to having to jump through various hoops to get models into a game engine Unity is quite simply a breath of fresh air. There are two main licenses: Unity Indie ($199), and Unity Pro ($1499). Unity Pro is required for businesses with over $100,000 turnover/year.
Our movie was produced via the 30 day trial of the Indie version, we will be taking a closer look at Unity over the coming weeks, for now see http://unity3d.com/unity/ for more information.
