That kind of a visual thing is purely client-sided and will be adjusted/added to a text file called "charactervisualchange.txt", which is at the media.pk2.
You can do things like this:
And yes, the one who has the client with the changes will have them on their client.
It is like an "invisible hack", which you can only see, if you have only made it for yourself.
Editing one line at a time will only affect one level of the invisible-skill. Same goes for the jobsuits. These here are just 3 of few jobsuits. You can clearly see the difference and the separation.
But yea. Just do mess around with the file and the already existing lines, and you might figure it out, sooner or later.
