I have created my own paint schemes and would like to share them but they all seem to be locked so when my friends try to search by creator they cannot find me so I don’t understand what I am doing wrong
So are you able to share them live and your friends can’t find them or is the problem that you just can’t share them. From your wording I assume it’s the latter. If so then you must ensure that all vinyls / logos etc. used in your design are your own and not downloaded. You cannot share a design that contains a vinyl/image/logo etc that were downloaded - it will lock the complete design.
If you want to use a certain image or logo on your design, the only way is to download it, copy/mask over it in the livery editor and then apply your own creation to your design.
