I've made some templates for the livery-icon-editor in AC Content Manager. It contains the numberplate from the german ADAC GT Masters and three numberplates from Blancpain. Additionally two new font-presets. A small one for the ADAC template and a LCD-Font a little bigger (just for fun).
Installation:
decompress files to
c:\users\[your username]\AppData\Local\AcTools Content Manager\Data (User)\Livery
to use LCD-Font you may install the lcdn.ttf contained in the file to your windows-font-directory
Hope it's userful.
