With the release today of Blender 2.77 RC2, I take a look at the new features added to Blender.
Most specifically I look at the functionality that is most important to game developers, including the edit mode boolean modifiers, the automatic UV creation and most importantly the new grease pencil functionality, that make Blender for 2D animations much more viable.
The full release of Blender 2.77 should come very soon.
