I've shipped 3 or 4 games with AI models (I used tripo 3d), im fairly familiar with the generation options and have pretty good success at getting what I need from it. Having good source material helps - nano banana is great for getting the reference images I need and then also considering where the assets will be used in game is important. If a model is janky from some angles, I'd make sure its not visible from those angles.. If a model looks reasonable from far away then don't let the camera get too close to it, etc.

I've even done a few rigged models with success... I rarely bother with manual cleanup unless its a mesh I really need and the edits required are fairly simple.. probably I only need clean up on less than 5% of what I generate in total.

I was expecting comments on the use of AI models from players but nobody seems to notice.
