I started intruding into the game folder and saw that all the scenes are in png format, so because of boring I took some, I passed them through Picsart to play a little on the girls, increasing muscles or making them more marked, then I put the images in the respective folders with the same name and to surprise the changes were saved.
Excuse me Tim if I profane your incredible masterpiece, I try not to be disrespectful since your work is amazing, but I feel that the minor changes are fine. I would still like to learn to model and achieve something similar to what you do, although I am very, very new to this, I don't even know what programs I could use.
