Quoting Preston the insane Petrolhead
By the way, how do you make the letters on the liscence plate? Please tell me in a comment on one of my mocs, but if it's too complicated, dont worry about it. :D
this only works on universe 1st you hit the paint tool then under the paint tool there is 4 things you can hit (left to right) paint tool, color selection tool, color picker tool, and decoration tool. hit the decoration tool and click on the flat 1x2 (this tool will work with bricks that fave flat surfaces includes slanted ones).
