In response to a specific request I made this 15 minutes video tutorial on how to create a hud that puts your textures on Slink hands and feet. Before you can make any hud you need to apply for a designer kit on their website. After you got your script pack and authorization you can start building your own hud. The video tutorial is showing you how to do that. The pack also includes the readymade (empty) hud, the used textures and some info on how I created the button textures.
Watch this promo video to see if the full version could be of use to you. It is available as group only item in the main store. And to give you something to practice on I released the full pack Christmas stockings as well complete with PSD and PNG files – Group only as well
