Importing blender model - no texture details

Hello unity people,

Im quite new to unity, but I didnt find a good solution for my problem in the internet (probably I dont know what to search for?)

I took this blender Model http://www.blenderguru.com/tutorials/create-a-realistic-earth/#.VCWsShZuSLM and tried to put it into my game so I can put it in as model for game object. Worked quite good, except the planet doesn't have all those details like on the picture. Its just a blue planet. Ive read about taking a transparency shader, but that didn't work. (Maybe I've done it in the wrong way?)

Would be cool if anybody could help me out here!:)
