NOTE 1: This product is a .lib4d file which you need to put in your /library/preferences/maxon/YOURVERSIONOFC4D/library/browser
After putting the _Designers-Pack.lib4d file into that folder, restart Cinema 4D, open up your Content Browser and it will show up as a folder in your presets.
NOTE 2: The textures may need to be modified according to your lighting set-up. Lighting has a huge effect on how textures look, so just keep that in mind.
