Developing sprite sheets with gpt-image-2

so I just spent $40 on pretty much all the image gen tools and have learned a valuable lesson: it remains unscalable, very difficult to produce a consistent isometric sprites i’d be happy to hear anyone with success . i first had gpt image 2 produce some decent animation with sprite but closer inspection shows that it is no consistent at all. not even nano banana 2 is able to produce any sort of game quality assets consistently
