First Attempt at 3D AI: Hand Mesh with Stable Fast 3D

I decided to try for the first time AI-assisted 3D modelling by using the Stable Fast 3D (SF3D) model. Just for fun, I decided to try out what SF3D could do with a hand model (as AIs stereotypically suck at drawing hands) and to my pleasant surprise I got a quite decent output (of course, with horrible topology, but that was expected).

I first generated a 2D picture of a hand with Stable Diffusion. Then, I used the ComfyUI 3D pack extension to generate the mesh with SF3D and finally, I did a quick retopology in Blender (there is definitely room for improvement in the topology, but I just wanted to do a quick test). In the video, I used two levels of the subdivision surface for the render (the actual retopology has a far lower face count at 292 faces).

I didn't texture the retopologized model because I would normally do UV-unwrapping before attempting to texture the model (I could have used a procedural shader, but I recently changed my PC and have yet to transfer to my new PC the folder with all the custom shaders).

Overall, I find some potential in this technique, especially considering that it was pretty low on computational requirement (SF3D ran super smoothly on my 12GB GTX4070 super). I will probably try doing some more complex 3D models in the future.
