Unity3d game development-simple transparent shader Skill Training

Next we will start today's unity3d game development skill transparent shader skill training. We have learned the unity3d training goal: to allow U3D beginners to quickly master U3D technology, create and modify materials on their own, and develop small-scale 2D and 3D games and web games independently.
