In response to a bunch of requests for me to share my AE CC 2015 style UI color scheme for Cinema 4D that I have in my tutorials, here it is!  This scheme only works in Cinema 4D R16 & up due to the updated UI in versions R16 & up (including R20!)

To install, unzip the file & place the entire eyedesyn_DarkUI folder in your scheme folder which can be found in Applications > MAXON > CINEMA 4D RXX > resource > modules > c4dplugin > schemes

Restart Cinema 4D and go to Edit > Preferences and under Interface go to the Scheme dropdown menu and choose eyedesyn_DarkUI
