Hi, I am kind of new to modding. I am trying to make a mod that will overlay the players skin with a rainbow one that cycles through colors. I have most of it figured out but I need a way to overlay the player's skin with the rainbow skin that I can then use to color cycle. I have done many searches but couldn't find anyway to do it. Thank you for reading this and I hope I can get the issue solved.
