Hi! First of all, thanks for the comment and for your interest in the pack! To answer your question: the 3D models, UV mapping, and bone rigging are 100% handcrafted by me from scratch. For the textures, I gather my own photo references and only use AI as an assisting tool to blend them together. After that, I manually adjust and create the retro PSX style myself. Everything is fully tested and optimized for game engines. Hope this helps, and feel free to ask if you have any more questions!
