You don’t have to use AI to generate everything. You could have it only replace certain aspects of your workflow. Ex: You could use a tool which looks at the 3d model you created/bought and then have it create a texture based on your prompt: https://github.com/FrederikHasecke/diffused-texture-addon
As others have mentioned, a consistent style will be an issue with AI generated… Anything.
There are ways to fix this. Either fine-tune your own model or create a Lora that will force the result to be consistent. You would need to learn how to do this by feeding it your own drawing style.
Copyright will always be an issue, it’s on you to make sure that any result from the model does not infringe on anything (ex: asking it to make you an image/model that looks like Pikachu is certain to draw the attention of Nintendo’s lawyers).
From what I understand, an art “style” can not be copyrighted, but definitely do some research on what could still happen. For instance, look at how Nintendo has reacted to Palworld, they can’t sue them for using a similar style, but (in Japan at least) they can go after them for using specific game mechanics such as “throwing a ball object to have a creature appear where it is thrown”.
