Unity 5 New Physically Based Texture Graphics

Ok, so I download the latest Unity 5, and now exploring how to make cool graphics...

I found the following youtube video

So basically,

1. Launch Unity 5

2. Create a new sphere

3. go to http://www.cgtextures.com/ to get some texture you like
(example brick -> rock)

4. Okay, so if you just use the texture and slap it directly into your new material and directly into your sphere, it look like below in Unity 5

4. after you download the texture, you can go to photoshop or gimp or crazybump to do "normal map"

5. export your "normal map" and put it into your material

Now the sphere have more detail instead of look plain
