My experience here has been so bad with the topology that I usually use the created mesh as an example and rebuild the whole thing from scratch to reduce the verts. Not even worth the time.
Honestly more of a reinforcement learning AI problem than a generative AI problem IMO
Virtually all the dominos have fallen except good topology at the moment, and unfortunately that's the biggest domino there is.
AI videogen and image gen will hollow out a lot of 3d work that isn't explicitly gaming oriented IMO, and eventually even that work may go away once better World-Action-Models come online.
