Ive never once successfully gotten a usable sprite sheet out of ChatGPT. The concept seems foreign to it and no matter how hard I try to steer it it’ll find a way to do something hopeless (inconsistent frame sizes; incoherent animations; no sense of consistent pixel sizes or what distinguishes (say) 8-bit from 16-bit era sprites; it’ll draw graph paper in the background for some reason; etc etc.). If anyone has a set of magic prompts for this, I’d love to learn about it. But my suspicion is that it’s just fundamentally the wrong tool for the job — you probably need a purpose-built model.
