Quote - The library window has a button "Materials". You have to click that. This Library button is only visible while you are in the Material room.

Thank you for your answers. And Yes, I did click the Mat.tab in the Library. Thats where I didnt find any materials, so to speak. But anyway, nodes and stuff are things I need to explore. Do you know any good tutorials for mat.room and nodes and these things. I´m eager to learn..
