How can i create a new skin for GTA V? Darth Vader?

[hachecach]

Hello, i looked everywhere for information about how can i insert a new player skin for Gta V and i didn't find anything. Only for changing t-shirts, or objects like this one:

For example, i have a Darth Vader .obj model. Now, which is the process to take it to the game? Is there any tutorial? Or perhaps somebody can teach me here.

 

I can see the .obj in photoshop and in 3dsmax, and i can export in dds in photoshop, but how many parts or differents dds must i make before import to ydr with texture tool kit? How many files and how must i organize them?

 

Thanks if anybody answer.
