Hello, I'm using C4D Lite R21 on a MacBook Pro, and am quite new to it, so please forgive my ignorance. As I'm doing tutorials, I'm realizing that my materials are clearly missing or are not installed correctly. When I go to my content browser and search "metal" for instance, I only get one result; for "Ceramic": nothing. Are they in the wrong place? I've attached a screenshot below of how things are situated on my system. Does it call for re-installing C4D, and if so does that mean I'd do so by deleting AE and reinstalling that? Any guidance would be greatly appreciated.
