Art of Blender
The Art of Blender is full of inspiring renderings from Blender artists around the world.
In this tutorial we examine how to export a model from Blender to Unity 3D and import it into a game. The tutorial also demonstrates how to bake a normal map and a color map from a highpoly model to the lowpoly counterpart, real-time display of the color/normal maps in the Blender viewport with GLSL shading, and real-time updating of assets in Unity.
Note: Unity 3D is a free-to-use (for most things) game engine that is available here: http://unity3d.com/
