I keep hearing the same problem — you use AI to generate game assets but a warrior, a potion and a chest all end up looking like they're from 3 different games. Mismatched styles, broken hands, inconsistent lighting.

Is this actually a pain point for you or do you have a workflow that fixes it? If it's a real problem I'm building something that lets you describe your art style once and generates unlimited matching assets. Happy to give free early access to anyone willing to give honest feedback.

There’s no way to achieve consistency with generative AI. Respect yourself and work with an artist or learn to draw.

The few people that create games with ai and put the effort into it, to have a consistent style obviously do have ways to do that. And there are plenty of guides describing the techniques to do just that. As a hint, you can train models and you can keep recurring prompt modifiers. As for styles that are already in the model, it is trivial to tell the system to just use that style. That's bascially the root of a lot of ai hate and ai made fake problems. You can tell it to create a painting in the style of Van Gogh. You can tell it to have a character look like a publicly known person.

And my guess, if you start putting effort into it, there is a turning point, where you would just switch to a 3d rendering and just fiddle around with how to position your characters. This keeps the style consistent and does not label your game to be ai made.

There are some few things to achieve consistency. IDK what AI you use, i will explain how i do. 

I use Krita with the plugin 'Krita AI Diffusion'. If you don't know them. Krita is a  free 'photoshop clone' and the plugin i mentioned is a unofficial add-on that let you run either cloud or local diffusion models. (i use the latter).

Also, you need to draw, if you have an idea in mind it will be more easily to draw what you want and then use the 'refiner' option of the plugin. (The more clearly/better you draw, the better results you will have). 

I'd recommend you use a checkpoint-specific-style per art style instead of a 'all in one'. Also, if you already draw, you can train a Lora in your own style.  

Broken hands, is like weird faces or weird eyes. Using some text inversions can help. But working over the generated images is still mandatory. There is no such thing as 'create everything with a prompt' That's more a marketing stuff. 

Extra fingers are done normally by 'cutting' the finger, editing the wrong hand, selecting that area and refine with 40 or 50% strength (less may be needed sometimes).
Faces sometimes is as easy as selecting the face, use: "High quality,HD,hd,high quality" as prompt with an intensity of 50% or less. If the problem is you don't have consistent faces between images (like if they belong to different people and not your characters) then tool like FaceFusion helps (Basically you do a DeepFake of your characters).

Ai is a tool. Is a matter in learning how to use it. Like i said before, many people was caught up with the advertising that they could to anything with a simple prompt. But is like redonihunter just said. As an artist/musician/programer (the creator) you have to put some effort in it.
