It’s definitely not a few sculpts and normally would be in thousands per my understanding.
I wouldn't assume you need thousands for something that just mimics RBF weighting based on a few example poses
I'm not talking about training full skinning weights but blend shape weights based on local space bone transforms
RBF itself is example based technique, not sure why would ML need more examples to figure out simple weights
Oh I see, you mean to infer {bone transforms -> blend shape weight}. Then the best solution is... probably just RBF.
We will only know when we actually see it, but I really don't think when you have only a few examples, more complex network will perform better than RBF. The math behind RBF is actually very similar to neutral network.
Not trying to be a know-it-all, but let's be factual. The AI/ML space is innovating so fast that anything we say today is very likely to be much less accurate tomorrow. What used to need 24Gb of VRAM or more are running on cellphones now and not even high end ones. That isn't a great example, just an example. Fully expect that whatever issue you dream up will be a nothingburger within short order.
