Does roblox have a "screenshot" function that you can access? I'd like to make it so that after, you customize your player, the game will take a screenshot of your players face and that will be your "player image" by your healthbar. I know people have done this by getting the userid of the player, but that only get's the picture of what clothes and hats they were wearing when entering the game and what they look like on their profile page. In the customization menu, I'm allowing players to change their hair, face, clothes, etc. If there is any function or way to do this that I'm not aware of than i'll be thankful for any answers.
Although this doesn't exist. You can do a nasty hack and render the character in a players camera and with scripts, preform the math to keep the parts next to the health bar. Yes, ugly hacks makes games look cool.
Info: Try looking for games that show the character parts on your screen, but no one else can see them.
Edit: Cool not cook..
Nick has the right idea, with rendering and all, but you could also make pre-made images of every possible combination if you want to get the exact image you want every time. This shouldn't take much time if it's only all the face combinations.
