Tom, the only installer is for version 6 of Corona, ; I tried to launch it, with the library of materials underneath, but in C4d I always have version 7, without library... there is no installer for 7? am I missing something? in any case, it doesn't work... if I understand correctly, the library should appear in the "corona" palette, and not in the "content browser" of C4d, where the other material folders appear... thanks for your help!
