After I finished the first version of my character customization system i just realized its such a piece of crap, so i started writing a new version with a whole new concept. The first version worked with CJ skin and i just attached some custom head models to it.
Conversely the new version is running with shaders and the skin is a custom dff. Here is a video of the head customization. The clothing is in progress yet, it takes a lot of time because i have to make custom cloth models. Hope you like it.
Please don't ask for the source code, this script will never be released. Sorry.
