unity, mesh Collider

关闭mesh Renderer以便查看mesh Collider

"For Unity 5, we must also select "Convex" on the Mesh Collider, in order for the Mesh Collider to work correctly with the updated Physics Engine."

如果不勾选Convex,能运行，但console下会出错误提示：

“Non-convex MeshColliders with non-kinematic Rigidbodies are no longer supported in Unity 5.0.”

如果创建一个Quad仅用于显示，应将其mesh collider删除。
