Here is a free video tutorial how to use 3D Coat’s intuitive 3D unwrapping tools. I go through the process of marking and optimising seams, unwrap, and pack UV islands on UV efficiently. It’s really quick and easy to unwrap model in 3D Coat. This feature has been a pinnacle feature of 3D Coat since version 3, but the new version have even better and more efficient tools.
Please see my 3D-Coat 4.7 (2016) review here.
