Jonathan Williamson has a new tutorial up on BlenderCookie that shows how to export low-resolution polygonal geometry with textures into the Unity game engine.
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.
